[Study on chemical constituents of Smallanthus sonchifolius].

OBJECTIVE

To study the chemical constituents of Smallanthus sonchifolius.

METHODS

Chemical constituents were separated through chromatographic methods and their structures were elucidated by spectral analysis.

RESULTS

Seven compounds were isolated from the chloroform fraction of 75% alcohol extract from the leaves of Smallanthus sonchifolius. Their structures were elucidated as gallic acid (1), beta-sitosterol (2), behenic acid (3), Kaempferol (4), Quercetin (5), vanillic acid (6), hexadecanoic acid (7).

CONCLUSION

Compounds 1, 4, 6 and 7 are isolated from this plant for the first time.
