Results: One new stereoisomer of biphenylneolignan with four known compounds was isolated from the leaves of Patrinia villosa Juss. Methods: The structure of the new compound was elucidated as 2,6,2',6'-tetramethoxy-4,4'-bis (1,2-trans-2,3-epoxy-1-hydroxypropyl) biphenyl (1) on the basis of spectroscopic analysis and comparison with literature data. The four known compounds were identified as 2,6,2',6'-tetramethoxy-4,4'-bis(1,2-cis-2,3-epoxy-1-hydroxypropyl)biphenyl (2), 1H-indole-3-carbaldehyde (3), luteolin (4) and quercetin(5) by comparison of their spectral data with the reported data, respectively. Conclusions: Compound 1 is a new biphenylneolignan, compound 2 and 3 were isolated for the first time from the plant.
