[Studies on chemical constituent of Solanum lyratum].

OBJECTIVE
To study chemical constituents of Solanum lyratum.


METHOD
The constituens were isolated by polystyrene resin RA, sephadex LH-20 and silica gel column chormatography, their structures were identified by spectroscopic analysis.


RESULT
Four compounds were identified as The constituens were caffeic acid, vanillic acid, rutin and N(p-hydropheneethyl) p-coumaramide.


CONCLUSION
These compounds were isolated from this plant for the first time.
