The essential oils were isolated by hydrodistillation from different parts of Alpin/a spp. and Boesenbergia spp. The oils were then analysed by capillary gas chromatography equipped with either flame ionization detector (GC/FID) Or mass spectrometer (GC/MS ). Percentage yield of essential oil from Alpin/a spp. and Boesenbergia spp. studied were in the range of 0.56% to 5.86% and 5.70% to 16.33%, respectively. Rhizome oil of A. galanga, A. galabra and A. aquatica were dominated by p-myrcene (30.71%), aromadendrene (48.72%) and y-selinene (48.37%), respectively. Stem oil, leaves oil and flower oil of A. galabra are comprised mainly of a-gurjunene (52.40%), cis-sabinene hydrate (16.28%) and (Z)-caryophyllene (51.99%), respectively. p-bourbenene (79.6%) and t-muurolol (25.39%) are the major compounds identified in the leaves and fruit oils of A. aquatica. Major compounds that were identified in the rhizome oil of B. rotunda, B. pulchella and B. parva are trans-pinocarveol (38.89%), p-selinene (36.92%) and (+)-Ppinene (3.76%), respectively. Toxicity test on Artemia salin. was pcrfonned for all the essential oils obtained. The result indicate that all the essential oils have not shown any significance toxicity effect towards Artemia salina.
