Sample extracted from leaves and the level of content were examined using the Densitometric Thin-layer Chromatography (TLC) methods with the pure betulinic acid commpound as a standar. In this paper, we describe the various content of betulinic acid of Andalas Tree and discuss its potentiality as source of medicinal product based on the recent references.
