1Key Laboratory of Bioactive Substances and Resources Utilization of Chinese Herbal Medicine, Institute of Materia Medica, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing 100050, China.
Objective:
To study the chemical constituents from herbs of Erigeron breviscapus.
Method:
The compounds were isolated and purified by various chromatographic techniques. Their structures were identified on the basis of physicochemical properties and spectral analysis.
Result:
Twelve compounds were isolated and structurally identified as quercetin-3-O-beta-D-glucoside (1), 5, 7-dihydroxychromone (2), 3-O-caffeoyl-gamma-quinide (3), naringenin (4), 3, 5-di-O-caffeoylquinic acid (5), 3,4-di-O-caffeoylquinic acid (6), 4, 5-di-O-caffeoylquinic acid (7), 1,3-di-O-caffeoylquinic acid (8), 1, 5-di-O-caffeoylquinic acid (9), 3-O-caffeoylquinic acid (10), 4-O-caffeoylquinic acid (11) and chlorogenic acid (12).
Conclusion:
Compounds 1-4 were isolated from this plant for the first time.
