Abstract

To investigate the chemical constituents of the aerial parts of Plumbago zeylanica Linn.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.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).Compounds V, VII, VIII and IX were isolated for the first time from Plumbago Linn.
