Objective:
To study the chemical constituents of Stelmatocrypton khasinum.
Method:
Using chromatographic methods to isolate compounds from S. khasinum and chemical and spectral methods to elucidate their structures.
Result:
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.
Conclusion:
Except compound 2, all the compounds were obtained from this plant for the first time.
