Abstract
Curry leaf tree Murraya koenigi L. Spreng. has an aromatic smell which are normally used as natural flavoring in curries and commonly found in India and Peninsular Asia. Curry leaf tree is known to be the richest source of carbazole alkaloids. The dried ground of the stem barks and roots were soaked in various solvents hexane chloroform and methanol to give different types of crude extracts. The separation of crude extracts was carried out using chromatographic techniques. The isolated compounds were identified as mahanimbine 1 girinimbine 2 murrayanine 3 murrayafoline-A 4 3-methylcarbazole 5 and bsitosterol 6. The structures of these compounds were established using infrared spectroscopy lR mass spectrometry MS and nuclear magnetic resonance NMR techniques. The crude extracts of the plant were tested against the larvae of Aedes aegypti. The LC50 and LC90values of the bioassays showed that the crude extracts were strongly toxic to the larvae of A. aegypti.
