[Studies on chemical constituents of Stelmatocrypton khasianum (Benth.) H. Bail].
OBJECTIVE
To study the chemical constituents of Stelmatocrypton khasinum.


METHODS
Using chromatographic methods to isolate compounds from S. khasinum and chemical and spectral methods to elucidate their structures.


RESULTS
Eight compounds, cleomiscosin A(1), 4-methoxy salicylicaldehyde(2), vanillin(3), isovanillin(4), 4-methoxy salicylic acid(5), isovanillic acid(6), 2,4-dihydroxy-benzoic acid(7) and 4-hydroxy-benzoic acid(8) were isolated from the stem of S. khasianum.


CONCLUSIONS
Except compound 2, all the compounds were obtained from this plant for the first time.
