Saurusine B: A new lignan from Saururus chinensis / 中草药

ABSTRACT

Objective: To study the chemical constituents in the whole plants of Saururus chinensis. Methods: The chemical constituents were isolated by various column chromatographic methods. The structures of the compounds were elucidated on the basis of physiochemical properties and spectrascopic analysis. Results: Seven compounds were obtained and identified as trans-7, 8-dihydro-7-(3,4-methylenedioxyl)-phenyl-1'-(2-oxopropyl)-3'-methoxy-8-methylbenzofuran (1), 4-(3-methoxy-4-hydroxy) phenyl-3- methyl-3-buten-2-one (2), (+)-guaiacin (3), (+)-trans-1,2-dihydrodehydroguaiaretic acid (4), (-)-isolariciresinol-4-O-β-D-glucoside (5), isonectandrin B (6), and perseal F (7), respectively. Conclusion: Compound 1 is a new compound named as saurusine B, and compounds 2-7 are obtained from this plant for the first time.
