Received Date: 30 August 2006

Fund Project: Financial support was provided by grants from the National Natural Science Foundation of China (No. 20432030) and National Key Basic R&D (973) Project (No. 2004CB518906). We are grateful to the Department of Instrumental Analysis, Institute of Materia Medica, Chinese Academy of Medical Sciences & Peking Union Medical College for measuring X-ray diffraction, NMR, and MS spectra.

A new triterpene, named cynanotriterpene A, with a ring-A-fission (3, 4-seco) and 13, 27-cyclours-3-oic acid methyl ester skeleton was isolated from the roots of Cynanchum forrestii Schlechter. The structure of the new compound was elucidated on the basis of spectroscopic method and X-ray diffraction.
