Biyouxanthones A - D, Prenylated Xanthones from Roots of Hypericum chinense
摘要:
Four new prenylated xanthones, biyouxanthones A - D (1 - 4), were isolated from roots of Hypericum chinense. The gross structures of 1 - 4 were elucidated from spectroscopic data, and 2 was assigned as a racemate by chiral HPLC analysis. Biyouxanthones A (1) and B (2) exhibited anti-viral activity against hepatitis C virus (HCV).
