Fund Project: We are thankful to Associate Professor Bing-Hui Chen from South China Institute of Botany,Chinese Academy of Sciences for taxonomic identification. Thanks are also due to Prof. Jie-Ping Zuo for biological tests. This work was financially supported by the National Natural Science Foundation for Outstanding Youth (30125044). This work was also partly funded by the "foundation for scholars come back from abroad" provided by Ministry of Education, Ministry of Personnel, and Chinese academy of Sciences.

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.
- Daphniphyllum oldhami,
- triterpenoid,
- 2-O-caffeoylalphitolic acid,
- methyl 2-O-caffeoyl-alphitolate
