[Chemical constituents from aerial parts of Plumbago zeylanica Linn].
OBJECTIVE
To investigate the chemical constituents of the aerial parts of Plumbago zeylanica Linn.


METHODS
The constituents of the EtOAc-soluble portion in the 95% ethanol extract were isolated and purified by means of chromatography. Compounds were identified by their physical characteristics and spectral features.


RESULTS
Nine compounds were isolated as plumbagin (I), isoshinanolone (II), plumbagic acid (III), beta-sitosterol (IV), 4-hydroxybenzaldehyde (V), trans-cinnamic acid (VI), vanillic acid (VII), 2, 5-dimethyl-7-hydroxychromone (VIII), indole-3-carboxaldehyde (IX).


CONCLUSIONS
Compounds V, VII, VIII and IX were isolated for the first time from Plumbago Linn.
