The aim of the present study was to evaluate physicochemical and phytochemical analysis of different parts (ripe seed, unripe seed, ripe peel, unripe peel and stem) of Indian mango (var. \‘Kesar\’) collected from Saurashtra region of Gujarat. The physiochemical properties such as loss on drying, total ash value, acid insoluble ash value, water soluble ash value and extractive values were carried out. The phytochemical properties such as alkaloids, flavonoids, tannins, phlobatanins, triterpenes, steroids, saponins and cardiac glycosides were also carried out. In phytochemical analysis, tannins showed maximum amounts in all five parts. The present study provides the details physicochemical and phytochemical properties of different parts of kesar mango which are useful in laying down standardization and pharmacopeia parameters.

Objective: The aim of the present study was to evaluate the antioxidant activity and total phenol and flavonoid content of different parts (peel, pulp and aerial parts) of Lagenaria siceraria. Method: Successive extraction was done by cold percolation method using solvents of different polarity viz. petroleum ether, toluene, ethyl acetate, acetone, water. Total phenol content was determined by Folin-Ciocalteu\’s reagent method and flavonoid was determined by aluminium chloride colorimetric method. The antioxidant assays evaluated were 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity, 2, 2\’-Azino-bis-(3-ethyl) benzothiazoline-6-sulfonic acid (ABTS) radical cation scavenging activity and Ferric reducing antioxidant power. Results: L. siceraria peel possessed maximum phenol and flavonoid content in acetone and toluene extracts respectively. FRAP was maximum in acetone extract of peel. The peel extract demonstrated stronger DPPH activity with IC50 value of 111 \μg/ml followed by pulp extract. The same extract was effective in scavenging ABTS radical with an IC50 value of 39 \μg/ml while other parts were ineffective. Conclusion: This work demonstrated good antioxidant activity of L. siceraria vegetable cultivated in India and recommends that the peel of this vegetable may be of interest from a functional point of view as a major source of natural antioxidant.

Objective: The aim of present study was to carry out Pharmacognostic and physicochemical analysis of Terminalia arjuna (Roxb.) Wt. and Arn. (family;Combretaceae) leaf. Method: The present study deals with pharmacognostic characters as identification parameters of the leaves which were subjected to macro and microscopic studies. Phyto- physicochemical studies were done by using WHO recommended parameters and fluorescent behaviour of the leaf sample was also tested. Results: The microscopy study revealed the presence of anomocytic stomata, trichome, xylem fibres, calcium oxalate crystals, vascular bundles, etc. Macroscopic study show alternate thick-coriaceous base obtuse-subcordate while margin was crenate-serrate, obtuse or sub acute at apex. Physiochemical parameters such as ash values, loss on drying, extractive values, fluorescence analysis were also determined. Preliminary phytochemical screening showed the presence of alkaloids, flavonoids, tannins, triterpenes, cardiac glycosides and saponins. Conclusions: The microscopic and physiochemical analysis of the T. arjuna leaf is useful in standardization for quality, purity and sample identification.
