A COMPARITIVE STUDY OF PHYTOCHEMICALS AND ANTIOXIDANT ACTIVITY AMONG TRADITIONAL MEDICINAL PLANTSAbstract
Acetone extracts of the three medicinal plants Sida cardifolia, Phyllanthus amarus and Adathoda vasica were assessed for phytochemical components qualitatively and quantitatively and antioxidant activity. The results revealed that all the three contained alkaloids, carbohydrates, flavonoids, tannins, anthocyanins, steroids and phenols. Saponins were absent in all the three extracts. Sida cardifolia with 1.53mg and 7.09mg GA equivalent/g of extract powder showed maximum amount of Phenolics and flavonoids.The total sugars and proanthocyanidins was maximum in Phyllanthus amarus with 8.45ug glucose equivalent/g of extract powder and 10.84mg GA equivalent/g of extract powder. Tannin content was found to be high in Adathoda vasica with 11.07mg GA equivalent/g of extract powder. Sida cardifolia acetone leaf extract showed the highest reducing power activity, Free radical scavenging potential and inhibition of lipid peroxidation.
