[Chemical constituents of Solanum cathayanum].
OBJECTIVE
To study the chemical constituents of Solanum cathayanum.


METHODS
Chemical constituents were isolated by chromatographic methods and identified by NMR analysis.


RESULTS
Five compounds were isolated and identified as lignoceric acid (I), beta-sitosterol (II), lupeol (III) 8-hydroxy-3-methoxy-5H-pyrido [2, 1-c] pyrazin-5-one (IV), ethly 2,6-dioxo-1,2,3,6-tetrahy-dropyrimidine-4-carboxylate (V).


CONCLUSIONS
Compound I and III are isolated from this plant for the first time. Compound IV and V are isolated from the genus of Solanum for the first time.
