Abstract

Phytochemicals are famous for their vital role in the development and protection of plants and our environment. The present research studies confirm the presence of plenty of phytochemicals including alkaloids, tannins, terpenoids, and flavonoids. The results that P.denticulata and P.stewartii possesses several classes of secondary metabolites. The preliminary phytochemical screening of Primula denticulata leaf extract showed that the plant is rich in various active ingredients (secondary plant metabolites). The result of the phytochemical screening revealed a strong to moderate presence of alkaloids, phenolic, flavonoids, tannins, cardiac glycosides, terpenes, Saponins, steroids and carbohydrates in P.denticulata .The Qualitative phytochemical screening of Pimpenella stewartii were studied having standered protocols for the detection of various secondary phytoconstituents to find out the medicinal potential of P.stewartii . Secondary metabolites like Alkaloids,  Flavonoids, Tannins, Saponins, Phenol, Phenol, Diterpenoids, Triterpenoids, Glycosides, Cardiac glycosides and Coumarins were examined by using different protocols  and tests such as Wagner’s test, Dragendroff’s test, Mayer’s test, KOH (alkaline, Gelatin test. Froth test. Ferric Chloride, Copper acetate, Liebermann-Burchard reaction, Legal’s test (Sodium nitroprusside), Keller Kiliani test, Ethanol + KOH were carried out. Alkaloid, Falavonide, Saponins, Phenol, Diterpenoids and Triterpenoids were highly present in the extract of P.stewartii.  While having Tannins, Glycosides, Cardiac glycosides and Coumarines were not present in  P.stewartii crude extract during experiment’s.
