PHYTOCHEMICAL SCREENING OF VARIOUS ETHANOLIC SEED EXTRACTS
Delphin.D.V, Haripriya.R, Subi.S, Jothi.D and P.Thirumalai Vasan*
ABSTRACT The screening and study of four different seeds belonging to different families for phytochemical constituents was performed using generally accepted laboratory technique for qualitative determinations. The constituents screened were tannins, saponins, terpenoids, flavonoids, glycosides, carotenoids, steroids, protein, carbohydrate and alkaloids. The distribution of these constituents in the seeds were assessed and compared. The plant seeds studied were Phoenix dactylifera, Manilkara zapota, Artocarpus heterophyllus and Carica papaya. Results revealed the presence of saponins, tannins, flavonoids, alkaloids, carbohydrates, phenolic compounds and carotenoids in the ethanolic extract of Carica papaya seeds. In case of other seeds, ethanolic extract of Phoenix dactylifera contains saponin, terpenoids, phenolic compounds and glycosides. Ethanolic extracts of Manilkara zapota contains tannins, terpenoids and phenolic compounds whereas Artocarpus heterophyllus extract showed the positive results for saponins, tannins, terpenoids and flavonoids. Keywords: Plant seeds, ethanolic extract, phytochemical constituents. [Download Article] [Download Certifiate] |
