| Abstract: | Object To define suitable gathering season of Ginkgo biloba L. leaves. Methods The content of total flavonoids and total terpene lactones in G. biloba leaves were determined by HPLC DAD and HPLC ELSD. Results The content of total flavonoids and total terpene lactones in G. biloba were distinct in different ages of tree and collecting seasons. Conclusion The content of total flavonoids and total terpene lactones in G. biloba are the highest in 2 3 ages of tree. The total flavonoid is the highest in May and total terpene lactone is the highest in September. |
| Keywords: | Ginkgo biloba L leaves total flavonoids total terpene lactones season ages of tree |
