摘要： Chemical investigation of the twigs extract of tropical dipterocarpaceous plant Shorea obtusa Wall led to the isolation of two previously undescribed oligostilbenoids, including a structurally unusual resveratrol aneuploid named shoreanol A (1) and a new resveratrol trimer derivative named shoreanol B (2). Their structures and relative configurations were determined by comprehensive spectroscopic analysis and comparison with previously reported compound. Shoreanol A (1) was identified as a rare natural resveratrol aneuploid possessing a novel carbon skeleton through condensation of three resveratrol monomer and one benzyl moiety, which is the first example in the Dipterocarpaceae. While shoreanol B (2) was characterized to be the first example of stilbene trimer bearing an epoxy group in the genus Shorea.
