Leaf essential oil composition and bioactivity of Psidium guajava from Kathmandu, Nepal
AUTHOR(S): Prabodh Satyal, Prajwal Paudel, Bimala Lamichhane, William N. Setzer
ABSTRACT:The essential oil from the leaves of Psidium guajava, collected from Kathmandu, Nepal, was obtained by hydrodistillation and analyzed by GC-MS. A total of 53 compounds were identified, accounting for 100% of the oil composition. The major components of the essential oil were (E)-nerolidol (35.6%) and (E)-caryophyllene (15.8%), with lower concentrations of (2Z, 6E)-farnesol (6.7%), and ledol (5.5%). A cluster analysis of the major components of P. guajava leaf oils has revealed at least nine chemotypes; the sample from Nepal belongs to the nerolidol/caryophyllene chemotype. P. guajava leaf oil showed notable larvicidal activity against Chaoborus plumicornis, marginal nematicidal (Caenorhabditis elegans) and insecticidal (Drosophila melanogaster) activities, and showed no antimicrobial or cytotoxic activity.
