Abstract The essential oils of the leaves and fruits of Murraya koenigii Spreng. were analyzed by GC and GC/MS. Forty-eight constituents of the leaf oil representing 95% of the oil and 42 constituents of the fruit oil accounting for 98.5% of the oil have been identified. The major constituents of the leaf oil were α-pinene (9.0%), α-phellandrene (6.1%), β-phellandrene (50.1%), (E)-β-ocimene (7.1%) and β-caryophyllene (4.9%). The main constituents of the fruit oil were α-pinene (48.1%), β-pinene (7.1%), myrcene (3.1%), β-phellandrene (26.0%), γ-terpinene (3.0%) and β-caryophyllene (3.0%).
