Abstract
The basic chemical composition of the leaves of Bursera species and their natural behaviour on herbivores was investigated in the present study. Leaf extracts of three Bursera species such as Bursera penicillata, Bursera vejar-vazquezii and Bursera trifoliata, and their effects on herbivores were observed. Extracted plant samples were analyzed through GC-MS and compared with different standard chemicals to determine their identities. Compounds from Bursera penicillata were rich in α-pinene, β-pinene, sabinene, β-myrcene, β-cadinene, α-farsenene etc. whereas, the extracts from Bursera trifoliata contained different siloxanes and β-caryophylline. A similarity of some chemicals (eg. Phillandrene, Germacerene) occured in Bursera penicillata and Bursera vajer-vazquezii leaves. Chemical contents of the leaves of Bursera penicillata and Bursera vegar-vazquezii were largely apparent and differed from those in the leaf extract of Bursera trifoliata. Among different essential oils only β-caryophylline remained in leaves of three species. This β-caryophylline and limonene showed their effects on the pest insect behaviour. This result might be helpful for future studies of chemical diversification of intra-species of plants as well as their natural behaviours on other animals.
