1Department of Pharmacy, Gansu Provincial Maternity and Child Health Hospital, Lanzhou 730050, China.
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) .
Conclusion:
All compounds are isolated for the first time from this genus.
