A new sucrosephenylpropanoid ester from Polygonum pubescens Blume

The present study investigated the chemical constituents of aerial part of Polygonum pubescens Blume. Twenty-two compounds 1–22 were obtained from petroleum ether and ethyl acetate extracts of aerial part of P. pubescens, including a new phenylpropanoide esters 1 and 21 known compounds. The structures were determined on the basis of spectroscopic and chemical methods. Sixteen compounds were assessed for their cytotoxic and anti-inflammatory activities. Several compounds showed effects on different targets.
