[Studies on chemical constituents of Suregada glomerulata II].

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.
