The chemical structure of the new unknown glycoside was confirmed as gcran)'t 00-ct-i.-arabinop)'ranosyl-fi-D-g]ucopyranoside (geran)'1 fi-viclanoside) by spectrometric anal)'ses and by an enzymatic hydrolysis-'ithglyeosidasefo)lowedb)'GC-MSandHPLCanslyses. Moreover the vicianoside was hydrel)'zed with acetone powder obtained from fresh tea leaves to ge"erate the same compounds, suggesting this...

Pharmacognostical parameters for the leaves of Tridax procumbens L were studied with the aim of drawing the pharmacopoeial standards for this species. Macroscopical and microscopical characters, physico-chemical constants, extractive values, fluorescence analysis of dry powder and its reaction after treatment with chemical reagents under visible light and UV light at 254 nm and 366 nm were stud...

The present study was carried out to investigate the effect of oral feeding of A. indica leaf (powder, aqueous and 80% ethanol extract) in STZ induced type 2 diabetic rats. Diabetes was induced by single intraperitoneal injection of STZ to 48hrs old pups and experiments were carried out three months later. For chronic experiment type 2 rats were divided into 5 groups: 1) Water control, 2) Glibe...

Hydrangeae Dulcis Folium, the fermented and dried leaves of Hydrangea macrophylla SER. var. thunbergii MAKINO, suppressed D-galactosamine-induced liver injury by 85.2% when added to the diet at 1% and fed to rats for fifteen days. The hepatoprotective effect is more potent than that of a milk thistle extract and turmeric powder. Some fractionated extracts showed hepatoprotective activity in the...

Powder characteristics are very important to consider in the tablet manufacturing process because they can affect of resulting tablets. This study aims determine microcrystalline cellulose powder isolated from soursop leaves. research method includes preparation leaves raw material, isolation α-cellulose using 17.5% NaOH solution with 3.5% nitric acid (containing 20 mg sodium nitrite), manufact...

Objective: The present work has been done to establish various pharmacognostical, physicochemical and phytochemical parameters of the leaf of Piper betle Linn. (Bangla variety) belonging to family Piperaceae. This could serve as a measure of authentication and quality control of the crude drug. Methods: Organoleptic, anatomical, microscopic, physicochemical analysis and preliminary phytochemica...

Dried leaves of Eucalyptus camaldulensis were finely grinded and fractionated by sieving into four granulometric classes (355 μm). The obtained powder fractions used for essential oil (EO) extraction hydrodistillation their phytochemical profile in vitro antioxidant activities evaluated. mother (unsieved powder) was comparison. Particle size exerted a significant influence (p properties the EOs...

Objectives: The main objective of this study is to cultivate Trichoderma harizanum using agricultural waste as a substrate for the management of damping of disease and growth promotion in Chilli plants. Methods: T. harizanum was isolated from MCRC Main Agricultural Research Station, Chennai, and identified through microscopic observation by using standard keys. F. oxysporum, R. solani, and A.al...

in this work, copper oxide nanoparticles have been synthesized via extractive rosmarinus officinalis leaves by simple and economic co-precipitation method at ambient conditions which it has used (ch3coo)2cu+h2o individually as cu sources. it was found that uniform copper oxide nanoparticles have been successfully produced at various temperature, namely 400, 600, and 800 0c. powder x-ray diffrac...

Several recent reports have been published indicating that the antioxidant activity of olive oil and tea leaves is not stable over product shelf lives of about one year. We have measured the antioxidant activity, total polyphenols, flavan-3-ols monomers, and procyanidin levels in milk and dark chocolate, in cocoa powder, and in cocoa beans. Results show that for the cocoa products studied, anti...
