Abstract:Three crystalline compounds have been isolated from the Desmodium triquetrum (L.) DC. On the basis of their spectroscopic data and chemical correlations, the structures have been identified as friedelin (Ⅰ), epi-friedelinol (Ⅱ), stigmasterol (Ⅲ). They were obtained for the first time from the Desmodium triquetrum (L.) DC.
