Chemical composition and biological activities of the essential oil from leaves of cleidion javanicum bl.

Abstract

The essential oil from the leaves of Cleidion javanicum Bl. was isolated by hydrodistillation with the percentage yield of 0.003 % as a pale yellow liquid. The composition of the essential oil was analysed by means of GC-(FID) and GC-MS. Ten constituents accounting for 92.60% total oil were identified. The major components were ethyl linoleolate (32.12 %), hexadecanoic acid (26.77 %), trans-phytol (24.64 %) and iso-phytol (4.80 %). The antimicrobial, anticancer, antioxidant activities and cytotoxicity test of this essential oil were investigated. The oil showed non-cytotoxic effects against Vero cells (African green monky kidney) because it inhibited more than 50 % cell growth. The anticancer activity of the essential oil was performed using the Resazurin Microplate Assay (REMA). The oil showed anticancer activity against three cancerous human cell lines; KB-Oral Cavity Cancer, MCF7-Breast Cancer and NCI-H187-Small Cell Lung Cancer with the IC50 of 47.16 μgmL-1, 40.23 μgmL-1and 49.95 μgmL-1respectively. The oil also showed antibacterial activity against Staphylococcus aureus and Pseudomonas aeruginosa with the Minimum Inhibition Concentration (MIC) values of 25.00 mg/mL and 12.50 mg/mL respectively, using agar diffusion method. In addition, the essential oil also showed significant antioxidant activity with the IC50of 27.05 mg mL-1by means of DPPH radical scavenging assay. © 2012, Copyright Har Krishan Bhalla & Sons.
