Abstract

Cananga odora (family Annonaceae) or locally known as ‘kenanga’, is native to Malaysia and Indonesia but also grown in moist forested areas especially in India, China and Southeast Asia. The high value of essentiallvo!atile oils (as fragran7un C. odorata, which is commercially known as ylang-ylang oil, is one of the good natural oils that shows many bioactivities for example, antioxidant properties since ancient times. The laboratory scale production of essential oils from fresh flowers and leaves of C. odorata was extraction using simultaneous distillation extraction (SDE) modified vith Likens-Nickerson apparatus. The yield of essential oil extracted with dichioromethane solvent from flowers was 0.50± 0.10% and 0.40±0.20% from leaves. The antioxidant properties were evaluated through the effects of essential oils on their capability to scavenge 2. 2-diphenyl-1-picrylhydrazyL (DPPH) radical in DPPH scavenging assay and the ability to inhibit lipid peroxidation activity through beta carotene bleaching assay. The flower and leaf essential oils showed moderate antioxidant activities in DPPH scavenging assay with 57.83ft70% of antioxidant activity from flower oil and 37.36±0.96% of antioxidant actMty from leaf oil. each at concentration of 100 pg/mI. In beta carotene bleaching assay, the flower and leaf oils showed quite high antioxidant activities at concentration of 100 pg/mI which were 61.83 0.53% and 57.20±1.04%, respectively. From this study, C odorata essential oils exhibited the potential to act as antioxidants due to the ability in scavenging free radicals, as well as in inhibiting lipid peroxidation process.
