Abstract:

The aim of study is to assess the antimicrobial activity and antioxidant activity of aqueous and alcohol extracts that were prepared from green leaves of Spinacia oleraecea, Allium cepa, Raphanus sativus. The antimicrobial activities of the extract were tested bacteria against E.coli, P.aurignosa, S.aureus, and B.subtilis by the use of agar well diffusion method. Antioxidant activities were tested by Reducing power assay method, Superoxide anion scavenging activity, Total antioxidant capacity.

Abstract:

The present study deals with the investigation of phytochemically evaluated ethanolic and aqueous extracts of leaves of Spinacia  oleracea for its anti-inflammatory activity. The anti-inflammatory activity was evaluated by carrageenan induced rat paw oedema method for acute inflammation and cotton pellet granuloma method for chronic inflammation. The standard drug used was  Indomethacin (20mg/kg) for both the models. In both methods, ethanolic as well as aqueous extract at a dose level of 1100mg/kg  has shown significant activity which is comparable to that of the standard.

Abstract:

Symptoms resembling powdery mildew appeared on spinach crops during April and May in 2007. Infected plants have suppressed growth, smaller and degenerated young leaves. The affected leaves become yellowish and wilt in a short time. High temperatures and draught conditions cause drying out of the affected plants. The symptoms are similar to physiological degeneration but are found on single plants or on small groups of plants. When plants are carefully examined, fine, exogenic mycelium is found on the leave blades. The mycelium can be clearly seen close to the main veins where it becomes denser

Abstract:

The present study tested with spinach (Spinacia oleracea L.), whether leaves are capable of long-term acclimative responses of carotenoids when warm-grown (20°C) plants were subjected to a regime of low temperature (1–6°C) and excess light (250 mol m–2 s–1). About 17 days after the temperature shift, leaves of the third leaf pair were compared with the respective leaves of warm-grown control plants. The cold-treated leaves exhibited reduced susceptibility to photoinhibition (at 4°C) and considerably faster kinetics of ‘recovery’ (at 20°C), as determined by changes in the ratio of dark-adapted

This paper presents the results of an experimental spinach (Spinacia oleracea) drying study in a new solar dryer. It is an indirect solar dryer with forced convection was developed and improved at the Food Science laboratory. Drying spinach leaves to a final moisture content of 2% from 93.2% (wet basis), with an air-drying speed equal to 1m/s. This study made it possible to determine the drying kinetics of spinach leaves, the evolution of the temperature profile a

Abstract:

Spinacia oleracea L. is an edible crop and considered as super food due to high nutrient values. Due to these properties the pot-based project was designed to explore the most diverse accession of this species, 31 local S. oleracea accessions were evaluated taxonomically on the basis of morphological and anatomical markers. Seeds were sown in clay pots to evaluate different morphological characters. The germination period varied from 6 to 15 days while variation in number of leaves was observed to be from 12 to 68 leaves per plant. Moreover, abaxial and adaxial epidermal leaf analysis was exam

Abstract:

Spinach ( Spinacia oleracia) and amaranth ( Amaranthus tricolor) leaves were stored in polyethylene bags and without packing for 24 and 48 hours in a refrigerator at 5°C and 30°C in polyethylene bags. The fresh leaves were also dried (oven and sun), blanched (5, 10 and 15 min) and cooked in an open pan and a pressure cooker. The processed leaves were analysed for total iron, its availability and antinutrient content. The iron content of these leaves varied from 26.54 to 34.14 mg/l00g, dry weight and its HCl-extractability and in vitro availability were 62.11–67.18% and 3.03–3.97% of total resp

Abstract: The current aimed to formulate herbal shampoo and to evaluate the various property of herbal shampoos. The herbal shampoo was formulated by adding the extracts of Spinacia Oleracea leaves, Ipomoea batatas roots, Acacia concinna, Sapindus Indica, Cymbopogon citrus in different proportions to a 100 ml. Small amount of gelatin and citric acid were also added for viscosity and pH respectively. Several tests such as visual inspection, pH, dirt dispersion, rheological evaluation and skin irritation test etc, were performed to determine the physicochemical properties of prepared shampoos. T

Abstract:

The aim of this study is to examine the thiol species for the high cadmium (Cd) tolerance of spinach and provide information for the improvement of soil utilization. The spinach was cultured in aqueous solution with concentrations of Cd ranging from 1 to 9 mg/L. The time responses of glutathione (GSH) and phytochelatins (PCs, PC2-PC4) in the tissues of spinach were monitored via HPLC–MS/MS, and the concentrations of Cd in the roots, shoots and leaves were detected by ICP–OES. Data were analyzed via one-way ANOVA and Spearman correlation to assess the relationships among the types of thiols and

The responses of certain antioxidants in detached leaves of two cultivars of spinach (Spinacia oleracea L.) differing in their senescence rates were assessed during storage in order to explore the significance of these antioxidants in senescence regulation and dynamics. To identify spinach cultivars differing in their senescence rates, 10 cultivars were grown in field plots, harvested at maturity, and their leaves detached and stored at 10 °C in the dark. At the point of harvest (d 0) and on d 5, 8, 12, and 15, samples were analyzed for lipid peroxidation (MDA), chlorophyll loss, and electroly

Abstract:

Nitrate content is an essential indicator of the quality of vegetables but can cause stress at high levels. This study aimed to elucidate the regulatory mechanisms of nitrate stress tolerance in spinach (Spinacia oleracea L.). We studied the effects of exogenous application of 15 (control), 50, 100, 150, 200, and 250 mM NO3- on spinach growth, physiology, and photosynthesis. The results showed that all the nitrate treatments inhibited the growth of the aerial parts of spinach compared to the control. In contrast, low nitrate levels (50 and 100 mM) promoted spinach root formation, but this effe

Abstract Four leafy vegetable species, spinach (Spinacia oleracea), amaranthus (Amaranthus viridis), fenu-greek (Trigonella foenum-graecum) and bathua (Chenopodium album), were extracted with three different solvents (80% ethanol, 80% acetone and water) for maximum recovery of phenol and antioxidant compounds in the extract. The results of extraction were compared with extraction from moringa (Moringa oleifera) leaves that is known as a very rich source of antioxidants. The study showed that, it is very difficult to justify a single solvent for extraction of antioxidant compounds from differen

Abstract:

Increasing the ability of the human body to adapt in conditions of physical or emotional stress is promising from the standpoint of the use of preventive nutrition containing functional food ingredients (FFI) with proven effectiveness in complex physiological in vivo studies. In this work, we developed FFI from spinach leaves (Spinacia oleracea L.) with a high content of polyphenols and adaptogens—phytoecdysteroids. Using in vivo models of increased physical activity and immobilization-induced emotional stress, we evaluated the nonspecific resistance of rats in response to the addition of the
