1Key Laboratory of Bioactive Substances and Resources Utilization of Chinese Herbal Medicine, Institute Materia Medica, Chinese Academy of Medical Sciences, Peking Union Medical College, Beijing 100050, China.
Objective:
To study the chemical constituents of Suregada glomeruldata.
Method:
Isolation and purification were carried out on silica gel, sephardex LH -20, ODS column chromatography etc. Constituents were identified by physicochemical properties and spectral analysis.
Result:
Nine compounds, Jolkinolide B (1), 8alpha, 14-dihydro-7-oxo-jolkinolide E (2), helioscopinolide B (3), ent-kauran-16beta, 17-diol (4), 7-oxo-beta-sitosterol (5), scopoletin (6), adenosine (7), 1'-sinapoylglucose (8), sucrose (9), were obtained and identified.
Conclusion:
Compounds 2-9 were isolated from S. glomerulata for the first time.
