Two new triterpene esters, 2-O-caffeoylalphitolic acid (1) and methyl 2-O-caffeoylalphitolate (2), together with two known triterpenes were isolated from the shrub Daphniphyllum oldhami. The structures of new compounds were elucidated on the basis of detailed spectroscopic analysis and compared with related compound.
