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