Two new resveratrol tetramers from Upuna borneensis

Chem Pharm Bull (Tokyo). 2009 May;57(5):516-9. doi: 10.1248/cpb.57.516.

Abstract

Phytochemical investigation of an acetone extract of Upuna borneensis (Dipterocarpaceae) resulted in the isolation of two new resveratrol tetramers, upunaphenols O (1) and P (2). The structures were elucidated by spectroscopic analysis including NMR experiments.
