摘要： The fruit of Lycium ruthenicum Murray has been widely used as a precious Chinese herbal medicine. In this study, the major anthocyanin in L ruthenicum fruit was obtained via an AKTA purifier system with YMC-Pack ODS-A column and identified by mass and nuclear magnetic resonance spectroscopy to be petunidin 3-0-[6-0-(4-0-(trans-p-coumaroyl)-alpha-L-rhamnopyranosyl)-beta-D-glucopyranoside]-5-0-[beta-D-glucopyranoside] (compound 1). Compound 1 exhibited higher scavenging activities against 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid), 1,1-dipheny1-2-picrylhydra-zyl and superoxide radicals than the crude extract of anthocyanins. Moreover, compound 1 was demonstrated to have potential cyto-protective effect on hydrogen peroxide-induced intracellular reactive oxygen damage in neuronlike rat pheochromocytoma line cells by promoting cell proliferation, mitigating lipid peroxidation and regulating endogenous antioxidant enzymes (glutathione peroxidase, superoxide dismutase and catalase).
