J Nat Prod. 1998 May;61(5):646-7. doi: 10.1021/np970457v.

Abstract

A novel tetrastilbenoid, flexuosol A (1), was isolated from the stems of Vitis flexuosa together with the known gnetin A, (+)-epsilon-viniferin, vitisin A, and hopeaphenol. The structure of 1 was elucidated using spectral methods.
