Screening for bioactive compounds in different plant parts of Calotropis gigantea L.

Abstract

The genus Calotropis R. Br., belonging to family Asclepiadaceae, is cosmopolitan in distribution. C. gigantea, commonly known as safed aak, grows abundantly in Rajasthan. The present study was design to analyze the qualaitative and quantitative in different extracts of Calotropis gigantea. Methanolic extracts of root, stem, leaf, flowers and fruit of C. gigantea were prepared via soxhlet extraction method. The screening was performed for carbohydrates, lipids, protein, phenols, tannins, flavonids, phytosterols, sennosides, anthraquinones. The color intensity or the precipitate formation was used as analytical responses to these tests. Quantitative analysis of compounds were done by established protocol.
