Pyranocoumarin and triterpene from Millettia richardiana.
From the stem bark of a Madagascan endemic plant, Millettia richardiana Baill., lonchocarpenin and betulinic acid were isolated and their structures established by spectroscopic methods. The analysis of dichloromethane fractions suggested the presence of beta-amyrin, lupeol, palmitic acid, linoleic acid and stearic acid. Except for beta-amyrin and lupeol, these compounds are described for the first time for the Millettia genus.
