Preliminary Phytochemical Screening of Methanolic Extracts of Green Grapes and Black Grapes (Vitis vinifera L.)

Meenal Sharma, Ritu Thakur Bais

The dietary consumption of grapes and its products is associated with lower risks of cardiovascular diseases and certain types of cancers. In present research, we have focused on comparing bioactive components present in green and black grapes (Vitis vinifera). Extraction of grapes was done by maceration process with methanol. Phytochemical screening was performed to detect the presence of alkaloids, flavonoids, anthocyanin, anthraquinones, saponins, steroids & terpenoids, carbohydrates, glycosides, phenol compound, protein and amino acids respectively. Black grape was found to be phytochemically richer as compared to green grapes. Results reveal that green grape extract contained alkaloids, flavonoids, anthraquinones, saponins, carbohydrates and phenol compound. Steroids and glycosides were not found in preliminary (qualitative) analysis of black grapes.

Keywords: Green and black grapes, Vitis vinifera, maceration, phythochemical screening, preminilary qualitative analysis
