Abstract:

A new triterpenoid, methyl buergericate (12a), which was elucidated as 2α,3α,19α,24-tetrahydroxyl olean-12-en-28-oic acid methyl ester by spectroscopic methods, together with eleven known triterpenoids was isolated from Rubus buergeri Miq. The isolation of the above chemical constituents from this plant was reported for the first time.
