Objective:
To study the chemical constituents of the aerial parts of Liusticum chuanxiong.
Method:
The chemical components were isolated by silica gel and Sephadex LH-20 column chromatography. Structures were elucidated on the basis of physico-chemical properities and spectral data.
Result:
Eight chemical constituents were isolated, and identified as protocatechuic acid (1), caffeic acid (2), scopoletin (3), apigenin (4), quercetin (5), cosmosiin (6), kaempferol-3-O-beta-D-glucopyranosid (7) and glucose (8).
Conclusion:
Compounds 1-8 were obtained from the aerial parts of the plant for the first time, compounds 3-8 were obtained from the plant for the first time.
