| Abstract | ||
| Eight taxa of Lauraceae representing four genera were subjected to the present study. The micro-morphological and chemical investigation were carried out according to traditional methods. The objective of the present study is to find criteria to facilitate the delimitation and identification of the taxa under investigation. The obtained leaf micro-characters were considered diagnostic at the generic and specific level. The extracted chemical compounds from the taxa under investigation ranged from 41-61. Most of tested oils showed antibacterial activity toward six bacteria strains. The most potent antibacterial oils were from Cinnamomum glanduliferum and C. verum. The antibacterial activity was due to oxygenated and non-oxygenated monoterpenes (α-pinene, β-pineneandcineole). The antibacterial activity of Apollonias barbujana is due to (α-phellandrene rather than cineole). The obtained data from an anatomical and chemical point of view can be considered diagnostic at the infraspecific level, but only to a certain extent. | ||
