Abstract:
SummaryTwo experiments were conducted on two varieties of Corchorus olitorius(‘NHCo 6’ and ‘NHCo 7’). The first one was on the effect of density of planting on their growth and development whilst the second was on the best planting ratio for Corchorus-tomato intercropping.There was no significant difference in morphological characters of the two varieties. The maximum value of leaf area index for the two varieties was around 3. Maximum marketable and edible yields were obtained for the two varieties at 30 × 5 cm (666600 plants/ha) and the best time for harvesting was 44 days after sowing.The best planting ratio for Corchorus-tomato intercrop was 2 rows of Corchorus and 1 row of tomato for maximum edible yield of Corchorus but for maximum economic returns, the best ratio was 1 row of Corchorus to 2 rows of tomato.

Abstract:
Crude protein separation was carried out for Corchorus incisifolious, Corchorus aestuans, Corchorus tridens and Corchorus olitorious using Sodium Dodecyl Sulphate-Polyacrylamide Gel Electrophoresis (SDS-PAGE). Plants were collected both from wild and cultivated sites and samples included leaves and seeds for the electrophoretic study. Distinct polymorphism in electrophoretic banding patterns of seed and leaf proteins following SDS- PAGE was observed in the four Corchorus species studied. Forty- two polypeptide bands were observed in the seed and a total of eleven polypeptide bands were observed in the leaves of the Corchorus species studied. The electrophoretic study revealed protein bands with various intensities ranging from high, to low and faint. The results showed that there was variation in both the seed and leaf proteins of the Corchorus species studied. A dendrogram constructed based on the Single Linkage Cluster Analysis (SLCA) clustering method revealed three major clusters for seeds. Cluster I consisted of C. incisifolious and C. aestuans, cluster II consisted of C. tridens, while cluster III consisted of C. olitorious. The leaf protein extracts were grouped into two clusters, cluster one containing C. incisifolious and C. aestuans, while the other contained C. tridens and C. olitorious.

Abstract:
This study is the first attempt to large-scale energy-efficient production of nanomagnetic Ni/NiO composites by using the autocombustion based on leaves or extract of corchorus olitorius. The as synthesized product can be characterized by using XRD, SEM, TEM and EDX techniques. The results confirm that the as synthesized materials consisted entirely of well crystalline Ni and NiO phases. The crystallinity of both Ni and NiO enhanced by increasing amount of the corchorus olitorius. However, the corchorus olitorius - treatment resulted in an increase in the crystallite size and lattice constant. The SEM analysis confirms formation of fragile, fluffy and spongy networks. The average of grain size for the as prepared particles was found to be 45 nm in agreement with the trend of the crystallite size calculated by using XRD technique. Furthermore, changing of nature and content of the corchorus olitorius brought about progressive modifications in the magnetic properties, namely, Ms, Mr, Mr/Ms, Hc and Ka, of the fabricated Ni/NiO nanocomposite according to the structural, morphological as well as microstructural variation. The saturation magnetization (Ms) of the sample with corchorus olitorius leaves was found to be 0.2383 emu/g while the Ms with corchorus olitorius extract was found to 6.977 emu/g. This was discussed in the light of finite size, surface and interface effects. Thus, we unveil a new approach for incandescent combustion synthesis via an innate approach for corchorus olitorius leaves in the directly fabrication for different nanocomposites.

Abstract:
Jute (Corchorus spp.) leaf has long been used as a remedy in many cultures. Jute leaf products, which include the leaf juice, fried leaf and some time whole green leaf are used, among other reasons, as laxatives, in creams for skin care, and as a treatment for a wide range of diseases, respectively. The heterogeneous nature of jute leaf products may contribute to the diverse biological and therapeutic activities that have been observed. The aim of the present study is to examine Corchorus olitorius whole plant for phytochemical profile. Qualitative analysis of various phytochemical constituents and quantitative analysis of total flavonoids were determined by the well-known test protocol available in the literature. The present study provides evidence that successive solvent extracts of Corchorus olitorius contains medicinally important bioactive compounds and this justifies the use of plant species as traditional medicine for treatment of various diseases. Quantitative analysis of flavonoids was carried out by aluminium chloride method. Phytochemical analysis revealed the presence of phenols, flavonoids, tannins, saponins, alkaloids, fixed oil and fats. The total flavonoids content of whole plant extracts was found to be chloroform- 0.505, ethyl acetate-1.300, methanol-2.050, aqueous-1.785 mg/100mg.The present study concluded that the crude extract of Corchorus olitorius is a potential source of various activates and this justifies its use in folkloric medicine.

Abstract:
Jinten hitam (Nigella sativa) is one of the medicinal plants in the family Ranunculaceae, native to the Mediterranean region and several regions of Asia. The seed of Nigella sativa is widely cultivated, distributed, and used in pharmaceuticals, cosmetics, and food industries. Due to similar seed morphology to its potential adulterant such as Corchorus spp., N. sativa seeds are susceptible to adulteration and substitution in markets. Molecular markers have become one of the most reliable methods for the identification and authentication of medicinal plants. The objective of this study was to select the random amplified polymorphic DNA (RAPD) primer for generating authentication methods of Jinten hitam (N. sativa). Genomic DNA was extracted from samples of N. sativa seed, Corchorus sp. seed, and a mixture of both samples. Forty-two random RAPD primers were used in this study. A total of 227 DNA fragments were produced from 37 amplified RAPD primers, out of which 65% were polymorphic. Primer OPK-4 and OPC-12 generated specific fragments in N. sativa, meanwhile, Primer OPB-1, OPL-5, OPM-3, OPD-5, and OPC-12 generated specific fragments for Corchorus. RAPD molecular marker was able to authentication Jinten hitam (N. sativa) and Corchorus sp. using a selected primer. This research was the first report on RAPD primer screening for Nigella sativa authentication from its potential adulterant (Corchorus spp.).

Abstract:
To contribute to the valorization of Corchorus plants, fifteen (15) communities in Côte d'Ivoire have been visited and 432 participants were selected, during an ethnobotanical survey. This survey helped us to identify four (4) different species of Corchorus which are: C. aestuans, C. lobatus, C. olitorius and C. tridens. These different species are grown by farmers in general and also by farmers of vegetables and foods crops. In Côte d'Ivoire these plants are called “Kroala”. Kroala is the name given by Baoulé people from the centre part of Côte d’Ivoire. Krola can be used as main ingredient in the cooking of soups and it can also be used as medicinal plant. At food level, the leaves of different species of Corchorus are used in the cooking of soups for several meals throughout the country. At ethnomedicinal level, these different plant species are used in the treatment of several pathologies such as anemia, constipation... For instance, leaves, roots, leafy stems and seeds of these plant species are used to make several monospecific drugs recipes. For the benefits brought by Corchorus plants to people, the growing of these plants must be encouraged throughout the country.

Abstract:
South Africa is known as food secure at a national level producing enough food coupled with the ability to import food if necessary to meet food and nutritional requirements of its population. However, the same cannot be said at a household level. Several rural households are still suffering from hunger, malnutrition, and poverty. One of the ways in which rural households can alleviate food insecurity and malnutrition is to increase the consumption of neglected indigenous vegetables such as Corchorus species. Corchorus has been reported to be rich in nutrients such as beta-carotene, Fe, Zn, Ca, Mg and could play an important role by providing relish with considerable amounts of nutrients to poor households. Its use as a food crop needs to be promoted and for this to be achieved there is a need to understand genetic background and generate knowledge for cultivation through plant breeding and precision agronomic studies. This study was therefore, undertaken to assess the genetic diversity and identify potential parents for future use in a Corchorus breeding program in the country. Eleven Corchorus accessions were sourced from Agricultural Research Council (ARC) and World Vegetable Centre (WVC) Taiwan, were evaluated in a field for morpho-agronomic and nutritional traits using a randomised complete block design with three replications across two cropping seasons in 2015/2016 and 2016/2017. The evaluated Corchorus accessions showed significant (P < 0.05) differences among them in both morphological and nutritional traits evaluated. Qualitative morphological characters were highly diversified in leaf colour, leaf shape, stem colour, pod and seed colour based on Shannon Weaver diversity index analysis. The multivariate analysis was used to determine the patterns of diversity among accessions. Morpho-agronomic traits for the first two principal components (PCs) accounted for 78.46% of the total variance and identified days to 50% flowering, plant height, canopy width, leaf length-leaf width ratio, leaf length, number of branches, stem diameter, pod diameter, number of pods, and number of seeds per pod as the most contributors to variation in the germplasm. Whereas for the nutritional traits the first two principal components accounted for 70.93% of the total variance with K, Ca, Mg, P, Fe, Mn, B, and Cu contributing most to variability. High level of variability was observed from the principal component biplot and cluster analysis among accessions. The ARC and WVC accessions were clustered into two different groups based on morphological traits. Genetic parameters were estimated for morphological quantitative and nutritional traits and showed considerable amount of genetic variability. High genotypic coefficient of variation (GCV), broad sense heritability (H2), and genetic advance (GA) were computed for plant height (59.2%, 89.2%, and 115.1), number of leaves per plant (39.7%, 74.7%, and 70.6), pod length (49.0%, 97.0% and 99.4), number of pods (144.4%, 80.1%, and 266.3), number of seeds per pod (54.1%, 88.4%, and 104.9), calcium (22.3%, 82.1%, and 41.6), magnesium (34.4%, 89.3%, and 66.9), and phosphorus (25.8%, 75.8% and 41.3), respectively, which permits effective selection. This study revealed sufficient genetic variability both for qualitative and quantitative morphological and nutritional characters among the Corchorus accessions, which could be exploited for the improvement in the Corchorus breeding programme in South Africa.

A Fabrica??o de novos materiais comp?sitos ? uma alternativa para substituir materiais convencionais, nesse intuito foi obtido e estudado a viabilidade do uso do Tecido Plano de Juta (TPJ) e tecido de fibra de vidro (TFV) em um comp?sito h?brido de matriz de resina poli?ster ortoft?lica. O processo de obten??o do comp?sito foi testado em rela??o ao n?mero m?ximo de camadas que poderia ser utilizado, sem comprometer a sua processabilidade e a fabrica??o dos corpos de prova (CPs) em molde compressivo. Foram escolhidas e testadas duas configura??es, h?bridas e n?o h?bridas, com 4, 6, 8 e 10 camadas de tecido plano de juta mais a resina ortoft?lica e 4, 6, 8 e 10 camadas de tecido plano de juta intercalados com o tecido de fibra de vidro mais a resina ortoft?lica. O comp?sito em suas duas configura??es e v?rias formula??es foi caracterizado para a determina??o de suas principais propriedades atrav?s das analises de tra??o, flex?o, impacto, densidade, absor??o de umidade, condutividade t?rmica, envelhecimento, MEV, DRX e FRX. No comp?sito proposto o TPJ e o TFV tiveram fun??o de carga de refor?o, com predomin?ncia para o TFV uma vez que todas as formula??es estudadas para o comp?sito h?brido apresentaram resist?ncia mec?nica superior ? da resina. A configura??o com 10 camadas de tecido de juta e 10 camadas de tecido de vidro 10TJV foi ? configura??o de melhor resultado de resist?ncia ? tra??o, ? flex?o e ao impacto. O melhor desempenho do comp?sito h?brido em rela??o ? resina foi ? resist?ncia ao impacto chegando a alcan?ar valores bem superiores, na ordem de 1000% maior em rela??o ? mesma. As propriedades t?rmicas do comp?sito h?brido foram competitivas com as da resina ortoft?lica, trazendo boas possibilidades para aplica??es t?rmicas. O MEV evidenciou que houve ader?ncia entre o TPJ, o TFV e a resina para todas as configura??es, por?m ocorreram fissuras, vazios e desprendimento de feixes de fibra. O comp?sito proposto apresentou viabilidade para a fabrica??o de prot?tipos solares e e?licos, como foi demonstrada pela obten??o de uma p? a ser usada em aerogeradores do tipo darrieus, e de uma par?bola que foi utilizada em um fog?o solar multifocal.
The manufacture of new composite materials is a cheaper alternative to replace conventional materials, in order to obtain the feasibility of using Jute Plane Tissue (TPJ) and fiberglass fabric (TFV) in a hybrid matrix composite Orthophthalic polyester resin. The process of obtaining the composite was tested in relation to the maximum number of layers that could be used, without compromising its processability and the manufacturing of the specimens (CPs) in compressive mold. Two hybrid and non-hybrid configurations were chosen and tested with 4, 6, 8 and 10 layers of jute flat fabric plus orthophthalic resin and 4, 6, 8 and 10 layers of jute flat fabric interspersed with the fiber fabric Glass plus orthophthalic resin. The composite in its two configurations and several formulations was characterized for the determination of its main properties through tensile, flexural, impact, density, moisture absorption, thermal conductivity, aging, MEV, DRX and FRX analyzes. In the proposed composite, the TPJ and TFV had a reinforcing load function, with a predominance of TFV, since all the formulations studied for the hybrid composite presented superior mechanical resistance to the resin. The configuration with 10 layers of jute fabric and 10 layers of glass 10TJV fabric was the configuration of best result of tensile, flexural and impact resistance. The best performance of the hybrid composite in relation to the resin was to the impact resistance reaching well higher values, in the order of 1000% greater in relation to the same. The thermal properties of the hybrid composite were competitive with those of the orthophthalic resin, giving good possibilities for thermal applications. The MEV showed that there was adhesion between the TPJ, the TFV and the resin for all configurations, but cracks, voids and fiber bundle detachment occurred. The proposed composite presented viability for the production of solar and wind turbine prototypes, as demonstrated by obtaining a shovel to be used in darrieus type wind turbines, and a parabola that was used in a multifocal solar cooker.

Corchorus olitorius L. is grown in Taiwan during summer. Tender leaves are crushed and washed by running water before cooking. In preliminary study, five fractions including crude phenolic extracts (using 80 per cent aqueous acetone) of whole plant, leaf, stem, washed leaf (WL) and dried water washing material (WW) were used in this study. Except for WL and WW, the phenolics of jute of all fraction showed the good antioxidative activity and the regulation of inflammatory responses, and the whole plant had the best effect. In the second study, five solvent extracts of tender leaves of Corchorus olitorius L. including n-hexane, ethyl acetate (EtOAc), acetone, methanol and water extracts, were used in this study. Acetone extracts showed better antioxidative activity and the regulation of inflammatory responses. Ethtlyl acetate (EtOAc) and methanol extracts also showed good inhibitory effects on inflammatory responses High levels of chlorogenic acid, caffeic acid and myricetin were detected in EtOAc and methanol extracts of Corchorus olitorius L. caffeic acid and an unknown compound were also detected in acetone and EtOAc extracts. This meaned that chlorogenic acid, caffeic acid, myricetin and the unknown compound A may play an important role on inflammatory regulation. The further study of the main contributors to antioxidation and inflammatory inhibition are required in future.

Corchorus capsularis L. is a traditional medicinal plant with hemostatic, apocenosis and detoxification functions. This study is to investigate the antioxidant activity of C. capsularis and the gastroprotective effect against ethanol-induced gastric mucosal lesions in rats. In antioxidant study, aqueous extract of C. capsularis (ECC) was prepared and subjected to analysis of polyphenols, flavonoids, polysaccharides and 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity. The results revealed that ECC contained polyphenols (59.88 ± 0.61 mg/g), flavonoids (86.39 ± 18.00 mg/g) and polysaccharides (320.89 ± 6.99 mg/g), in which polysaccharides content had at least 3.5 times more than that of polyphenols and flavonoids. The IC50 of DPPH free radical scavenging activity for ECC was about 0.25 mg/mL. The resulted indicated C. capsularis contained antioxidant components with free radical scavenging activity. In gastroprotection study, ethanol-induced gastric mucosal lesion was applied to evaluate the gastric mucosal protection of C. capsularis. The SD rats (7 weeks old) were divided into five groups of eight rats each including normal group, control group and three experimental groups as LECC (200 mg/kg), MECC (400 mg/kg) and HECC (1000 mg/kg). The results revealed that ECC had no significant effect on the body weight and food-uptake of rats in whole experimental period. Supplementation with ECC groups were capable of decreasing significantly the ulcerative lesion index (ULI) in a dose dependent manner as compared with that of control group (p<0.05) with inhibitory rate of 85.0 % at HECC group.In addition, Malondialdehyde (MDA) level of rats in ECC treated groups were significantly decreased, while the Glutathione (GSH)、Glutathione peroxidase (GPx)、Superoxide dismutases (SOD) and Catalase (CAT) were significantly higher than that of the control group. Histopathogical results showed significant decrease on lesion score of LECC (1.131.05), MECC (1.380.70) and HECC (1.000.71) as compared to that of control (2.380.70) (p<0.05), which was obviously supported the protective effect of ECC on gastric mucosal damage caused by ethanol. Literatures reported free radical production was one of mechanisms involved in ethanol-induced gastric mucosal damage. The animal experiments revealed ECC was able to enhance antioxidant capacity and diminish lipid peroxidation resulting in gastric mucosal protection. The overall results demonstrate that C. capsularis has protective effect on ethanol-induced gastric mucosal lesions in rats and has potential to be a health food with gastroprotection.

In this study, we used three extraction methods as fractionated with ammonium sulfate solution (50% w/v), hot water and microwave-assisted from leaves of Corchorus olitorius L. The content of polysaccharide was determined with phenol sulfuric acid method. Our results show that hot water extraction method from leaves of C. olitorius. (HWLC) was the optimal approach used for extracting polysaccharide compared to others. It showed with the advantages in high efficiency, energy and running time saving. TLC analysis shown HWLC containing galacturonic acid. Transepidermal water loss (TEWL) measurements in vitro with three sample as water, hyaluronic acid (HA) and HWLC were compared showed HWLC and 0.0001% HA has a similar degree of moisture capacity. Further to incorporate the phenolics extract from leaves of C. olitorius. with propylene glycol (PGLC). The content of myricetin was determined with HPLC-ECD measurement. PGLC and HWLC were then incorporated in the microemulsion formulations using ethyl oleate, tween 80, PGLC and HWLC as oil, surfactant, co-surfactant and water phase, respectively. The stability of the microemulsion has changed slightly.

This study was discussed the different parts of Corchorus capsularis, and their antioxidant activity and the ability on the inflammatory effects by LPS-activated macrophage cell line. In the antioxidant activity, CGLEE had the best suppression. In transient transfection assay showed that the CVHWE activated PPARγ significantly. The MTT assay results showed that Corchorus capsularis extracts treatments did not significantly influence the cell viability. However, the Corchorus capsularis leaf reject vein hot water extract (CLRVHWE) had no effect. The CCLEE could inhibited the PGE2 synthesis, and Corchorus capsularis hot water extract had no significantly difference. In addition, suppression on LPS-induced COX-2 protein expression of RAW264.7 showed that CGLEE was the best. The CLCVHWE and CLRVHWE inhibited COX-2 protein expression, but PGE2 had no different with vehicle. In the NF-κB p65 protein expression, the CSME and CLCVHWE had significant ability inhibition. In conclusion, the effects of CGLEE could suppressed NO2, PGE2 and COX-2 protein expression and decreased NF-κB p65 protein expression.

Corchorus olitorius is the tender leaf of jute, and well-grown in middle Taiwan during summer. The general edible method is to remove stem and the leaf vein of the plant, only use the tender leaf . Tender leaf was kneading by running water until the bitter taste was washed off. And is always boiled to eat as stew form. This study was to discuss the polyphenol contents of different parts of Corchorus olitorius, and their antioxidant activity and the ability on inflammatory regulation. Crude polyphenol extracts of whole Corchorus olitorius, Corchorus olitorius leaf, stem, the laundering Corchorus olitorius leaf and it’s washing dried material were used in this study. Results showed that total phenolic content of Corchorus olitorius was the highest in washing dried material(762.09±11.80 mg/g dry wt.), the total flavanonoid contents were the most abundant in the leaf (169.34±11.96 mg/g dry wt.), and the condensed tannin contents were mainly in stem(211.29±10.30 mg/g dry wt.). The reducing activity and the chelating activity on ferrous ion were greatly exhibited by the Corchorus olitorius stem and whole Corchorus olitorius. However, the scavenging activity on hydrogen peroxide were greatly by the washing dried material, and the scavenging activity on DPPH radical were by stem, leaf and whole Corchorus olitorius better than that of the laundering Corchorus olitorius leaf and its washing dried material. All polyphenol extracts of Corchorus olitorius showed higher inhibition than VitE on linoleic acid autooxidation. The suppression on LPS-induced nitrite production of J774A.1 macrophage cell clearly showed that polyphenol extract of whole Corchorus olitorius had the best suppression(65.2%)at 200μg/ml. Washing dried material had no effect on nitrite production. Except for washing dried material, the other polyphenol extracts inhibited nitrite production in a dose-dependent manner. The effect on LPS-induced PGE2 production of J774A.1 macrophage cell showed that polyphenol extracts of leaf had the best suppression(52.6%)at 200μg/ml, followed by whole Corchorus olitorius and stem. However, the laundering leaf and washing dried material almost had no effect on PGE2 production. Furthermore, the suppression on LPS-induced IL-1 production of J774A.1 macrophage cell, also showed that polyphenol extracts of leaf had the best suppression(79.5%) at 200μg/ml. The polyphenol extracts of Corchorus olitorius leaf, Corchorus olitorius stem and washing dried material inhibited IL-1 production in a dose-dependent manner. And whole Corchorus olitorius had suppression only at 200μg/ml, the laundering leaf almost had no effect on IL-1 production. Effect on LPS-induced iNOS expression of J774A.1 macrophage cell showed that the polyphenol extracts of Corchorus olitorius leaf had the best suppression on iNOS expression. All polyphenol samples inhibited iNOS expression and showed dose-dependent manner. In addition, suppression on LPS-induced COX-2 expression of J774A.1 macrophage cell showed that leaf was the best, followed by whole Corchorus olitorius, stem, laundering leaf and washing dried material. In conclusion, the effect of polyphenol extracts no inflammatory regulation showed that whole Corchorus olitorius and Corchorus olitorius leaf were better than those of stem, laundering Corchorus olitorius leaf and its washing dried material.
