Abstract:

Ho VT, Ngo QNg. 2017. Short Communication: Using RAPD technique to evaluate genetic diversity of longan (Dimocarpus longan) population in Vietnam. Biodiversitas 18: xxxx. Longan (Dimocarpus longan L.) is an important fruit plant in Vietnam where several cultivars and landraces are being cultivated. Presently, the identification of longan cultivars and landraces is mainly based on personal experience relying on morphological traits leading the difficulty of genetic conservation and longan breeding. In this study, genetic richness and relativeness of 36 longan accessions collected from different provinces in Vietnam were evaluated by using 30 Random Amplified Polymorphic DNA (RAPD) primers. Our results reveal that there is the large variation of genetic background of studied longan accessions with separate groups in the obtained dendrogram. We also identified the combination of different RAPD markers could help to identify 15 longan genotypes. The results from this project could provide valuable information which is necessary for classifying, identifying plant origins, breeding and conserving programs of longan in Vietnam.

Abstract:

Os objetivos deste trabalho foram avaliar os efeitos de crioprotetores na criopreservação e da sacarose na embriogênise somática de calos de Dimocarpus longan. Após degelo os calos foram cultivados em meio de multiplicação, e a massa da matéria fresca foi determinada. Para se obter os embriões somáticos, calos e massas pro-embriônicas foram transferidos para meio de cultura contendo diferentes concentrações de sacarose. Entre os crioprotetores, a mistura de 5% de glicerol + 5% de dimetilsulfóxido proporcionou a maior quantidade de massa fresca dos calos. O maior número de embriões foi obtido no meio de cultura com 50 g L-1 de sacarose. Os resultados mostram que calos de Dimocarpus longan podem ser criopreservados e plântulas podem ser obtidas.

Abstract:

Longan polysaccharide (LP) was extracted from longan (Dimocarpus longanLour.) pulp. The composition and rheological properties were determined by chemical analysis and dynamic shear rheometer. The flow behavior and viscoelastic behavior of longan polysaccharide (LP) solution were investigated by steady shear and small amplitude oscillatory shear (SAOS) experiments, respectively. The result shows that the solution is a pseudoplastic flow in a range of shear rate (1–100 s−1). The rheological behavior of LP was influenced by cations such as Na+and Ca2+. With an increase of apparent viscosity,G′andG′′were accompanied by addition of Na+and Ca2+.

Abstract:

The pharmacodynamic effect of longan leaves was attributed to various components, especially the flavonoids. In this paper, a new strategy of quantitative analysis of multicomponents by a single marker (QAMS) method was first established to synchronously determine 5 components (ethyl gallate (C1), astragalin (C2), quercetin (C3), luteolin (C4), and kaempferol (C5)) in Dimocarpus longan by ultra-performance liquid chromatography (UPLC) and high-performance liquid chromatography (HPLC). Quercetin (C3) was chosen as the internal reference. Relative correction factors (RCFs, ƒs/i) of the other 4 components were calculated by two correction methods (multipoint correction and slope correction) to effectuate QAMS. At the same time, the difference between the results measured by the QAMS and external standard methods was compared to verify the accuracy of QAMS. Within the linear range, the results showed that all ƒs/i values were obtained with good durability under diverse chromatographic conditions (RSD < 2.28%). The quantitative results of 5 components in the leaves of Dimocarpus longan collected from 10 producing areas by different chromatographic systems and quantitative methods were significantly correlated (Pearson’s r > 97.0%). The applicability and feasibility of the QAMS method established in this study were evaluated to be favorable for quality control of the leaves of Dimocarpus longan. As a new model of quality control, it can provide one more choice of multicomponent quality-control method in the absence of standard substances or instruments.

Abstract:

The MYB gene family is one of the most widespread plant transcription factor (TF) families, and MYB TFs play key roles in plant development, hormone signal transduction, disease resistance, abiotic stress tolerance and secondary metabolism. Recently, many MYBs have been characterized in various plants. However, little is known about the MYBs involved in secondary metabolite biosynthesis in Dimocarpus longan Lour. (D. longan). Based on transcriptome data profiling (Accession number: SRP155595), 35 MYBs from D. longan (DlMYBs) were identified. On the basis of their physicochemical properties, phylogenetic relationships, conserved motifs, and tissue-specific expression profiles these Dimocarpus longan MYBs (DlMYBs) were analyzed. Fifteen motifs in DlMYBs using MEME were found and a phylogenetic tree analysis showed that the DlMYBs identified here were divided into three groups. Group A contained the greatest number (25) of DlMYBs, followed by group B (6) and group C (4). Quantitative real time PCR (qRT-PCR) analysis demonstrated that, of the 35 MYBs studied DlMYB-12 and DlMYB-22 showed large differences in tissue-specific expression, with both MYBs showing very high expression in leaf tissue. These results lay the foundation for further studies of the biosynthesis of secondary metabolites in D. longan and further highlight the importance of MYB TFs in plants.

Abstract:

Starch was isolated from longan seeds of three widely distributed cultivars (Chuliang, Shixia, and Caopu) in China. Comparisons of the multi-level structure of the starch of longan seeds among various cultivars were made, and the relations between these structural and property characteristics are discussed. The isolated starch, accounting for 44.9–49.5% (w/w) in longan seeds, had an oval or an irregular polygonal shape with a smooth surface. Their chain-length distributions (CLDs) varied with longan cultivar; Chuliang showed a larger proportion of longer amylopectin chains with a degree of polymerization (DP) 30~100. This is attributed to the slightly higher relative crystallinity of Chuliang longan seed starch. Apparent differences were also detected in amylose structure. Caopu showed a higher amylose content than Chuliang and Shixia, resulting in its lower gelatinization temperatures and enthalpy change. All longan seed starch had a typical A-type crystal structure with relative crystallinity ranging 28.6–28.9%. For raw starch, Caopu showed the lowest digestion rate, followed by Chuliang; Shixia showed the highest. This is because Caopu had the highest amylose content. Chuliang had a more intact structure than Shixia, as suggested by its higher crystallinity, although they had similar amylose content. After being fully gelatinized, all starch showed a similar digestion process, indicating that the digestibility of gelatinized starch does not differ with starch source or structure.

Abstract:

Masalah yang sering muncul pada buah-buahan adalah adalah cepatnya mengalami kerusakan karena proses respirasi dan transpirasi sehingga akan memperpendek umur simpan. Salah satu upaya memperpanjang kesegaran buah Kelengkeng dengan pemakaian Edible Coating. Penelitian ini bertujuan untuk mengetahui kemampuan Edible Coating sebagai pengemas buah Kelengkeng selama penyimpanan. Perlakuan penelitian terdiri atas aplikasi Edible Coating (Kontrol) dan lama penyimpanan (1 hari, 2 hari, 3 hari, 4 hari, 5 hari dan 6 hari). Parameter yang diamati adalah susut berat, kadar air dan warna. Rancangan percobaan yang digunakan adalah rancangan acak lengkap pola faktorial dengan dua kali ulangan. Pengaruh perlakuan aplikasi Edible Coating dan lama penyimpanan berpengaruh sangat nyata terhadap susut berat, kadar air dan warna buah Kelengkeng. Penggunaan Edible Coating sebagai pelapis mampu mengurangi susut berat buah Kelengkeng, mempertahankan kadar air dan warna buah Kelengkeng selama penyimpanan. The problem that often arises in fruits is that they are quickly damaged due to the respiration and transpiration processes so that they will shorten their shelf life. One of the efforts to extend the freshness of Longan fruit is by using Edible Coating. This study aims to determine the ability of Edible Coating as a packaging for longan fruit during storage. The research treatment consisted of Edible Coating application (Control) and storage time (1 day, 2 days, 3 days, 4 days, 5 days and 6 days). Parameters observed were weight loss, moisture content and color. The experimental design used was a completely randomized design with a factorial pattern with two replications. The effect of Edible Coating application treatment and storage time had a very significant effect on weight loss, moisture content and color of Longan fruit. The use of Edible Coating as a coating is able to reduce the weight loss of longan fruit, maintain water content and color of longan fruit during storage

Abstract:

The longan industry produces a large amount of byproducts such as pericarp and seed, resulting in environmental pollution and resource wastage. The present study was performed to systematically evaluate functional components, i.e., polyphenols (phenolics and flavonoids) and alkaloids, in longan byproducts and their bioactivities, including antioxidant activities, nitrite scavenging activities in simulated gastric fluid and anti-hyperglycemic activities in vitro. Total phenolic and total flavonoid contents in pericarp were slightly higher than those in seeds, but seeds possessed higher alkaloid content than pericarp. Four polyphenolic substances, i.e., gallic acid, ethyl gallate, corilagin and ellagic acid, were identified and quantified using high-performance liquid chromatography. Among these polyphenolic components, corilagin was the major one in both pericarp and seed. Alkaloid extract in seed showed the highest DPPH radical scavenging activity and oxygen radical absorbance capacity. Nitrite scavenging activities were improved with extract concentration and reaction time increasing. Flavonoids in seed and alkaloids in pericarp had potential to be developed as anti-hyperglycemic agents. The research result was a good reference for exploring longan byproducts into various valuable health-care products.
