Description
Gotu kola is a perennial plant native to India and other tropical countries. Its appearance changes, depending on growing conditions. In shallow water, the plant puts forth floating roots and the leaves rest on top of the water. In dry locations, it puts out numerous small roots and the leaves are small and thin. The stems of the plant are slender, with creeping stolons, interconnecting one plant to the other. The rootstock consists of rhizomes, which grow vertically downwards. The rhizomes have a cream colour and are covered with root hair. The flowers of the plant range from pinkish to red in colour.
Plant Chemicals
Indocentelloside, brahmoside, brahminoside, asiaticoside, thankuniside and isothankuniside are the glycosides found in the plant. The corresponding triterpene acids obtained on the hydrolysis of these glycosides are indocentoic, brahmic, asiatic, thankunic and isothankunic. These acids, except the thankunic and isothankunic, are also present in free form in the plant, apart from isobrahmic and betulic acids. The presence of mesoinositol, ‘centellose’ (a new oligosaccharide), kaempferol, quercetin and stigmasterol, have also been reported. The main active ingredients found are Bacoside A and B.
