Abstract:
Objective: To study the chemical constituents from the root barks of Ginkgo biloba. Methods: The constituents were isolated by column chromatography and their structures were elucidated by physicochemical properties and spectroscopic analyses. Results: Thirteen compounds were isolated including four fatty acids, palmitinic acid (1), stearic acid (2), behenic acid (3), and lignoceric acid (4); one fatty alcohol, 1-heptacosanol (5); two sterides, β-sitosterol (6) and daucosterol (7); two flavonoids, genkwanin (8) and apigenin (9); and four ginkgolides, bilobalide (10), ginkgolide A (11), ginkgolide B (12), and ginkgolide C (13). Conclusion: Among them, compounds 3-5 are isolated from this plant for the first time. The results are helpful for the comprehensive utilization of the resources of the root barks of G. biloba.
