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 …

The essential oil of the leaves Solanium spirale Roxb. was isolated by hydrodistillation and analyzed for the first time using GC and GC-MS. Thirty-nine constituents were identified, constituting 73.36% of the total chromatographical oil components. (E)-Phytol (48.10%), n-hexadecanoic acid (7.34%), beta-selinene (3.67%), alpha-selinene (2.74%), octadecanoic acid (2.12%) and hexahydrofarnesyl acetone (2.00%) were the major components of this oil. The antioxidant activity of the essential oil was evaluated by using the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging assay. The oil exhibited week antioxidant activity with an IC50 of 41.89 mg/mL. The essential oil showed significant antibacterial activity against both Gram-negative Escherichia coli and …
