Vegetables are very rich in health-promoting phytochemicals like flavonoids and phenolic compounds. The objective of the study was to investigate the effect of commonly used cooking (i.e., open and pressure cooking) methods on phytochemical content (i.e., polyphenols, flavonoids) and antioxidant activity levels as measured by DPPH and FRAP assay. Results showed that cooking methods have a great effect on phytonutrients and caused significant losses of flavonoids and increase in phenolics and antioxidant activity levels when compared with raw vegetables. Bitter gourd scored the highest mean value, 1033.8 mg GAE/100g, and drumstick scored the lowest mean value, 222.3 mg GAE/100g, for total phenolic content. The flavonoid content ranged between 14.18 to 91.7 mg RE/100g in the selected vegetables. There was a significant increase (p< 0.01% and p<0.05%) in antioxidant activity levels in vegetables upon both open and pressure...

Mango is the most popular fruit having excellent flavor, pleasant aroma, attractive color, and taste. It is a good source of vitamin A and C, TSS (total soluble solids) and minerals. It is also a medium source of carbohydrate. Their fruit has distinct physio-morphological characteristic features and composition variation. Phenolics are aromatic benzene ring compounds with one or more hydroxyl groups produced by plants mainly for protection against stress. Phenolics play important roles in plant development, particularly in lignin and pigment biosynthesis. Phenolic is among the major contributors that are accountable for antioxidant properties in fruits, vegetables, whole grains, and other plant-based materials. Hence in the present study, the phenolic acid analysis was done by HPTLC for comparison between three varieties at unripe and ripe stages. Three varieties, namely alphonso, kesar, and rajapuri were studied extensively for the phenolic acid variations. Phenolic acids occur naturally in plants and are their main polyphenols. In plants, they act as signaling molecules and agents of defense. In humans, these compounds act as...

Herbal formulation is a dosage form consisting of one or more herbs or processed herbs(s) in specified quantities to provide specific nutritional, cosmetic benefits, and/or other benefits meant for use to diagnose treat, mitigate disease of human beings or animals and / or to alter the structure or physiology of human beings or animals. The world health organization (WHO) estimates that 80% of the population (Asian and African countries) presently use herbal medicine for some aspect of primary health care. The present work was designed to evaluate the phytochemical potential and qualitative analysis of Ashwagandha churna. It was a simple maceration technique of extraction was followed to get the purified drug for further investigations. The chemical test was evaluated for the detection of different constitute include alkaloid, starch, flavonoid, tannins, saponins, steroid, carbohydrates, phenol, glycoside, terpenoids, resins, cardiac glycoside, coumarins. The qualitative study investigation includes HPLC and TLC. The result demonstrated the successful presence of above...

The present study was carried out to evaluate the wound healing potential of different extracts of Oroxylum indicum leave in two different types of wound models in albino rats viz., incision and excision, and compare the effects with povidone iodine ointment which is used as standard drug. Among all the extract, the ethanolic extract at a dose of (250 mg/kg) possesses a significant increase in wound contraction and formation of scar in an excision wound model. The extract showed a significant increase in the breaking strength of resutured incision wound as compared to the control group (p<0.05). The result of the present study indicates that ethanolic extract of O. indicium has more significant wound healing property than the other two extracts in excision and incision wound...

Diabetes mellitus is becoming a threat to the world’s population as it is spreading like an epidemic. Pterocarpus marsupium Roxb., Azadirachta indica A. Juss., Trichosanthes dioica Roxb., S. cumini Linn. and M. charantia Linn. are well known for their properties in the management of diabetes. In recent times, there has been significant growth in the field of Ayurvedic medicines because of their fewer side effects compared to synthetic drugs. Thus, the study of medicinal plants is becoming an integral part of developing herbal medicines for the treatment of diabetes. The present study was performed to determine the pharmacognostic as well as phytochemical similarities and dissimilarities between root, stem, and leaf of these plants. Extensive usages of specific plant parts may lead to the extinction of plant species. To protect them, specific plant parts were thoroughly studied so that those plant parts can be replaced by another part (s) of the same plant. The comparative study included macroscopic observations, powder microscopy study, physicochemical and phytochemical analysis. The pharmacognostic analysis revealed...
