Spireasalicin, a New Acylated Quercetin Glycoside from Spiraea salicifolia

摘要

A new acylated quercetin glycoside and 36 known compounds were isolated from flowering runners of Spiraea salicifolia L. (Rosaceae). The structures of the new glycoside quercetin-3-O-[6″-(4?-hydroxy-2?-methylenebutyroyl)]-β-D-glucopyranoside (spireasalicin,1) and the 36 known compounds were elucidated using UV, IR, and NMR spectroscopy and mass spectrometry. The biological screening of the isolated compounds showed that1inhibited α-glucosidase. The contents of several phenolic compounds in S. salicifolia organs were studied and found to be unevenly distributed in the separate plant parts.]]>
