[Studies on the active constituents in vine stem of Spatholobus suberectus].
OBJECTIVE
To study the active constituents in vine stem of Spatholobus suberectus.


METHODS
The constituents of Spatholobus suberectus were systematically separated with various chromatographic techniques. The structures were elucidated by physico-chemical properties and spectral data.


RESULTS
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).


CONCLUSIONS
Compound 3, 4, 6, 7 were obtained from Spatholobus genus for the first time. Compound 4 has stimulation to proliferation of hematopoietic progenitor cell.
