Abstract

Komposisi minyak atsiri Citrus grandis, Citrus aurantium (L.) dan Citrus aurantifolia yang diperoleh dari distilasi uap dianalisis dengan KG-SM. Berdasarkan analisis KGSM, ketiga sampel tersebut kaya akan kandungan monoterpen, dan limonen merupakan senyawa mayor dengan prosentase berturut-turut 90,96; 84,92 dan 33,33%. Minyak atsiri dari kulit buah C. aurantifolia menunjukan aktivitas antibakteri yang paling baik (LC50 = 233,71 ppm). Minyak atsiri dari C. aurantium (L.) memiliki LC50 sebesar 292,32 ppm, sedangkan minyak atsiri dari C. grandis memilki aktivitas antibakteri terendah dengan LC50 = 465,84 ppm. Hasil uji larvasida menunjukkan bahwa minyak atsiri dari kulit buah C. aurantium (L.) memiliki aktivitas insektisida yang palig baik dibandingkan C. aurantifolia dan C. grandis dengan nilai LC50 299,95 ppm, 719,87 dan 995,64 ppm.

The compositions of essential oils (EOs) obtained by hydrodistillation of Citrus grandis, Citrus aurantium (L.) and Citrus aurantifolia were analyzed by GC-MS. According to GCMS analysis, the three samples were found to be very rich in monoterpenes, and limonene was the major compound with 90.96, 84.92 and 33.33%respectively. EO of C. aurantifolia peels exhibited greater antibacterial activity (LC50 = 233.71 ppm), followed by EOs from C. aurantium (L.) (LC50 = 292.32 ppm) and C. grandis (LC50 = 465.84 ppm). The larvicidal activities of peels essential oils from C. grandis, C. aurantium L. and C. aurantifolia were evaluated against larva of Aedes aegypti. Results of larvicidal tests demonstrated that the peel essential oils of C. aurantium (L.) was the most potent insecticide (LC50 = 299.95 ppm), followed by Eos from C. aurantifolia (LC50 = 719.87 ppm) and C. grandis (LC50= 955.64 ppm).
