Studies on the Chemical Constituents of Duzhong (The Bark of Eucommia ulmoides Oliv.)

Xu Jun-wen, Li Dong and Zhao Ping   

Abstract: Four constituents were isolated from the bark of Eucommia ulmoide; Oliv. Based on the physico-chemical constants, spectral analysis and properties of derivatives, they were identified as: liriodendrin (1), geniposidic acid (2), (+)-pinoresinol di-O-β-D-glucopyranoside (3), and daucosterol.

Key words: Eucommia ulmoides Oliv., liriodendrin, geniposidic acid, (+)-pinoresinol di-O-β-D-glucopyranoside, daucosteol
