Abstract
Aim:
To study the lignans from Patrinia scabra Bunge.
Methods:
The constituents were separated and purified by column chromatography with silical gel, RP-silical gel and Sephadex LH-20. Their structures were identified on the basis of spectral data (IR, MS, 1HNMR, 13CNMR, HMQC and HMBC).
Results and conclusion:
A new lignan was obtained and its structure was elucidated as 4-[1-ethoxyl-1-(4-hydroxy-3-methoxy)benzyl]methyl- 2-(4-hydroxy-3-methoxy)benzyl-3-hydroxymethyl-tetrahydro-furan (2), along with three known lignans, lariciresinol (1), isolariciresinol (3) and nortracheloside (4).
