Determine resource chemical component in ginkgo pollen simultaneously by UPLC-TQ-MS / 中国中药杂志

ABSTRACT

The present study is to determine the flavonoid glycosides, terpene lactones, biflavones, gingko acid and procyanidins of ginkgo pollen. UPLC-TQ-MS technology was used for the determination of 24 kinds of resource chemical composition in ginkgo pollen qualitatively and quantitatively. The results shows that the contents of rutin, quercetion 3-O-[4-O-(α-L-rhamnosyl )-β-D-glucoside] and kaempferolis were 120.9, 114.0, 222.1 μg x g(-1). In this paper, the contents of 24 kinds of chemical components of ginkgo pollen were determinated by UPLC-TQ-MS for the first time. This method is simple and quick, which will be benefit for recycling utilization of ginkgo pollen.
