[Studies on the chemical constituents of Chelonopsis albiflora].
OBJECTIVE
To study the chemical constituents of Chelonopsis albiflora.


METHODS
The compounds were isolated and purified by various column chromatographic techniques and their structures were elucidated on the basis of spectral analysis (EI-MS), 1H-NMR, 13C-NMR.


RESULTS
Seven compounds were isolated and identified as 1beta-hydroxylupenol (1), lupenol (2), beta-sitosterol (3), 13-epi-torulosal (4), 19-acetoxy-13-hydroxylabada-8 (17), 14-diene (5), (E)-p-methyl cinnamic acid (6) and vanillic acid (7) .


CONCLUSIONS
All compounds are isolated for the first time from this genus.
