Phytochemical Screening of some Orissa Plants for Tannins, Saponins, Flavonoids and Alkaloids

Eighty three plant samples collected from the forests of erstwhile Kalahandi, Keonjhar, Koraput, Cuttack, Dhenkanal and Khurda districts of Orissa were screened for finding out new sources of therapeutically important active compounds. Tannins were found in 33, saponins in 4, flavonoids in 19 and alkaloids in 7 samples. Out of 83 samples screened, 40 samples belonging to 34 species were found to respond negatively for all the above ingredients. Garuga pinnata was found to contain 24.7% of tannins in its bark and the presence of saponins was recorded for the first time in the fruits of Eriolaena hookeriana.
