Phytochemical investigation of the whole plants of Saururus chinensis resulted in the isolation of two sesquiterpenes (1 and 2), five lignans (3-7), one alkaloid (8) and two steroids (9 and 10). Among them, compound 3 has not been reported as a natural product before. Compounds 1, 2, 8 and 10 were firstly reported from the family Saururaceae. The possible biosynthesis pathway for sauchinone-like neolignans (6 and 11) was also firstly proposed. Furthermore, the chemotaxonomic significance of these compounds was summarized. |
