Abstract:
To compare the quality Ginkgo biloba L. leaves collected form various habitats, different tree ages, and different harvesting times and to confirm the source of G. biloba leave used in Xin Mai Capsule. To establish the HPLC fingerprint of G. biloba leaves to determine the fingerprint and content of total flavonol glucoside and terpene lactones in G. biloba leaves collected from various habitats, different tree ages, and different harvesting time, and then to analyze the results. The contents of total flavonol glucoside and terpene lactones and fingerprint similarity in G. biloba leaves from various regions, different tree ages, and collecting times were different. The fingerprint control method has provided the scientific basis for the reasonable collection and quality evaluation of G. biloba leaves. The G. biloba leaves in June to August, 2-3 year-old from Pizhou, Jiangsu province are better, which could be considered as the source of G. biloba leaves used in Xin Mai Capsule.
