The essential oils from flowers of Lavandula officinalis L. (L. officinalis
L. = L. angustifolia Mill.) were obtained by two hydrodistillation
techniques: standard (technique I) and modified (technique II) Clevenger
hydrodistillation. The yield, hydrodistillation kinetics, composition and
antimicrobial activity of essential oils were investigated. The higher yield
of oil was obtained by hydrodistillation technique II. The new analytical
hydrodistillation kinetics model of essential oil from Lavandulae flowers was
defined. The essential oil composition was analyzed by gas
chromatography-mass spectroscopy (GC-MS). There are differences in chemical
compositions of the oils obtained by different techniques. Antimicrobial
activity of essential oil obtained by technique I and II against Salmonella
enteritidis, Klebsiella pneumoniae, Staphylococcus aureus, Enterococcus
faecalis, Candida albicans and Aspergillus niger is the same, while the
activity against Escherichia coli and Pseudomonas aeruginosa is slightly
different.
