Abstract
[Objective] The aim of this paper was to study on the dynamic law of flavonoids glycosides contents in exotesta of Ginkgo Biloba L.at different growth stages.[Method] RP-HPLC method was used to detect the content of flavonoids glycosides.[Result] Flavonoids glycosides content in exotesta of Ginkgo Biloba L.increased gradually at the early growth stage.The maximum value(0.32%) occurred at 65th d of full bloom,and then decreased obviously.[Conclusion] With the growth of seed,content of flavonoids glycosides in the exotesta changed regularly with the growth period.
