摘要：
A new flavonoid, isorhamnetin-3-O-[--l-rhamnopyranosyl-(13)]--d-glucopyranoside (1), along with two known flavonoids 3'-O-methylorobol (2) and quercetin 3-O--d-glucopyranoside (3), was isolated from Alhagi maurorum. Their structures were established with the help of mass spectrometry, 1D and 2D NMR spectroscopy, and in comparison with the literature data. Compounds 1 and 2 exhibited moderate antioxidant activity in the 2,2-diphenyl-1-picrylhydrazyl free radical scavenging assay.
