Traditional and Medicinal Uses of Annonaceae

A mixture containing a new triterpene, chamaedrydiol (urs-12-ene-2α,3β-diol), and three known triterpenes (lup-20(29)-ene-2α,3β-diol, castanopsol and epigermanidiol) was isolated from Marsypianthes chamaedrys. The components in the mixture were identified using spectroscopic methods. In addition, a mixture of four less polar known triterpenes consisting of α-amyrin, β-amyrin, lupeol and germanicol, was also isolated.
