A study of the chemical components of Decalepis Hamiltonii (Makali Veru). Part IV. Rasinols of Decalepis Hamiltonii and Hemidesmus indicus

Abstract

The existence of resinol in the petrol-soluble portions of Decalepis Hamiltonii and Hemidesmus indicus has been established by the isolation of α- and β-amyrins and lupeol from them. They exist both free and as esters. The various fractions have been analysed using both the acetate and the benzoate methods. The roots of the Decalepis contain more of the amyrins and less of lupeol where as the Hemidesmus contains more of lupeol. The more soluble fractions of both roots seem to possess certain compounds having partly the properties of sterols and partly those of resinols. Further in Hemidesmus roots small amounts of tetracyclic triterpene alcohols also seem to be present.
