Studies on the Chemical Constituents of Erycibe hainanesis

Wang Pu, Yao Tian-rong and Chen Ze-nai   

Abstract: Five compounds have been isolated from the stem of Erycibe hainanesis Merr. They were identified as scopoletin (1), scopolin (2), baogongteng A (3), baogongteng C (4) and erycibelline (5) by spectral analyses as well as chemical methods. The derivatives, 4m, 5m and 5ma, are new tropane compounds', their spectral data and physical constants are reported in this paper. Erycibe hainanesis Merr. may replace Erycibe obtusifolia Benth. as a medicinal herb, and it is yet one of the plant resources of new myotic baogongteng A.

Key words: Erycibe hainanesis Merr., tropane alkaloids, baogongteng A
