ABSTRACT

The medicinal importance of a plant is due to the presence of some special substances like alkaloids, glycosides, resins, volatile oil, gum, and tannins etc. Considering all these facts the present study is designed to investigate the presence of various phytochemicals in two medicinal seeds. Out of which one is Flax seeds, and the other one is Nigella Sativa seeds. Both the seeds are rich source of healthy fat, antioxidant and fibre. The nutrient in in both the seeds help lower may risk of diabetes, cancer, heart disease and thyroid., and they have antioxidants, anticancer, anti-inflammatory and anti-thyroid activities. The present study deals with qualitative analysis which is done by (using standard method of Harborn) phytochemicals test of Alkaloids, Flavonoids, Terpenoids, Steroids, Phenols, Tannins, Saponins and Cardiac Glycosides followed by extraction of oil by Sohxlet apparatus. Quantitative analyses were also done to determine the amount of such phytochemicals by using standard method of Harborn 1973. Phytochemicals, alkaloids, flavonoids, terpenoids, steroids and cardiac glycosides are present in varying amounts which may be used in future for preparation of herbal medicine.

Keywords: Nigella sativa, Soxhlet apparatus, Cardiac Glycosides, Terpenoids, Tannins.
