Objective:To study the chemical constituents of the n-butanol extract of Stelmatocrypton khasianum. Method: The n-butanol extract was isolated and purified by silica gel column chromatography
HP-20 and Sephadex LH-20.Their chemical structures were elucidated by spectral data (1H-NMR
13C-NMR). Result: Five compounds were isolated from the n-butanol extract. They were identified as pregn-4-ene-3
20-dione ( 1 )
3β
5β-pregn-20-one-3-ol ( 2 )
3α-hydroxy-5β-pregnan-20-one ( 3 )
2β-hydroxy subergorgic acid methyl ester ( 4 )
suberosanoe ( 5 ). Conclusion: All compounds were isolated from this plant for the first time.
