Abstract

In the course of hepatoprotective screening for domestic plants. the aerial parts of B. vulgaris var. cycla exhibited hepatoprotective activity which was determined by using the primary cultures of rat hepatocytes injured by H2O2. Bioactivity-guided separation for this plant gave a new flavonoid (1) and the known compounds (2-4), which structures were elucidated by 1H-NMR, HMQC, 1H-1H COSY and HMBC as compound 1, apigenin 8-C-, 7-O-di-$\beta$-D-glucopyranoside, compound 2, vitexin 2"-O-$\beta$-D-glucopyranoside, compound 3, (+)-dehydrovomifoliol, and compound 4, 3-hydroxy-5$\alpha$, 6$\alpha$-epoxy-$\beta$-ionone.
