摘要
Identification and quantification of flavonol glycosides and secoiridoids was carried out on leaves of Ligustrum vulgare L. (Oleaceae) by means of HPLC-DAD and HPLC-MS analysis. In addition to previously reported secoiridoids (oleuropein, ligustaloside A, ligustaloside B, and ligstroside) four kaempferol glycosides (kaempferol 3-O-glucoside 7-O-rhamnoside, kaempferol 3,7-O-dirhamnoside, kaempferol 3-O-rhamnoside, and kaempferol 3-O-glucoside) and two quercetin glycosides (quercetin 3-O-glucoside 7-O-rhamnoside and quercetin 3,7-O-dirhamnoside) were present in leaves oft. vulgare L. Although secoiridoids accounted for nearly the 76% of the total leaf polyphenols content (with ligustaloside A as the main component), kaempferol glycosides were also accumulated in the leaves of L. vulgare L. to a relatively high extent (23%). Contribution of quercetin derivatives was minor under our experimental conditions. Our findings suggest that flavonol. glycosides may have a central role in both the ecology and the biology oft. vulgare L.
