Objective:
To study the active constituents in vine stem of Spatholobus suberectus.
Method:
The constituents of Spatholobus suberectus were systematically separated with various chromatographic techniques. The structures were elucidated by physico-chemical properties and spectral data.
Result:
Eight compounds were isolated from S. suberectus, and were identified as: ononin (1), pruneitin (2), gallocatechin (3), catechin (4), epicatechin (5), syringic acid (6), vanillic acid (7) and daucosterol (8).
Conclusion:
Compound 3, 4, 6, 7 were obtained from Spatholobus genus for the first time. Compound 4 has stimulation to proliferation of hematopoietic progenitor cell.
