Abstract

The volatile composition of the leaf of Artocarpus communis Forst (Moraceae) and root of Sphenocentrum jollyanum (Menispermaceae) were studied. The essential oils were obtained by hydrodistillation in a modified Clevenger-type apparatus while the analyses were performed by GC and GCMS.
The main constituents of A. communis (leaf) were á-pinene (14.1%), 6-methyl-5-heptene-2-one (7.0%), á-phellandrene (8.9%), á-ionone (6.1%), E-nerolidol (8.3%) and 1,8-cineole (5.5%). The main compounds
identified in the root oil of S. jollyanum were á-eudesmol (26.1%), á-pinene (11.2%), isocaryophyllene (7.7%), 1.8-cineole (6.3%) and â-pinene (5.3%). The yields of the oils were 0.15% and 0.20% for S. jollyanum and A.
communis respectively. The toxicity of both oils to the brine shrimp indicated that A. communis had LC50 of 24.50 ìg/mL and S. jollyanum 84.87 ìg/mL. A. communis showed very weak activity to P. mirabilis while S. jollyanum was active against B. subtilis and P. aeruginosa.
