The chemical composition and antibacterial activity of essential oils from 10 commonly consumed herbs: Citrus aurantium, C. limon, Lavandula angustifolia, Matricaria chamomilla, Mentha piperita, M. spicata, Ocimum basilicum, Origanum vulgare, Thymus vulgaris and Salvia officinalis have been determined. The antibacterial activity of these oils and their main components; i.e. camphor, carvacrol, ...
The essential oil content in the inflorescence of lavender (Lavandula angustifolia Mill.) cultivated in the mid hills of Uttarakhand was found to be 2.8 % based o n the fresh weight. The oil was an alysed by capillary GC and GC– MS. Thirty seven constituents, representing 97.81 % of the o il were identified. The major components of the oil were linalyl acetate (47.56 %), linalool (28.06 %), lav...
The xeromorphic adaptation of epidermal cells of Lamiaceae plant leaves, the conse quence of their adaptation to an arid habitat, was investigated. These xerophytic species inhibit transpiration in different ways, depending on the number, the form and the position of trichomes, whether they are dead hairs or live glandular structures. The Salvia genus is characterized on one hand by multicellu...
A Croatian indigenous cultivar of lavandin, Lavandula x intermedia 'Budrovka' (Lamiaceae) was studied for the phenolic acids, flavonoids, anthocyanins, procyanidins and total tannins, as well as total polyphenols content, in the flower, inflorescence stalk and leaf ethanolic extracts. Antioxidant potentials on these plant part extracts were assessed by the DPPH free radical scavenging activity,...
Even though the Lavandula species may be propagated by seeds, it should not be the preferred propagation method because it causes a great lack of uniformity. On the other hand, asexually propagated lavender crops would provide more homogeneous crops, and clones from high quality plant material would increase the odds for obtaining a higher quality essential oil. However, problems such as poor r...
The inhibitory effects of essential oils including clove, lavender and geranium extracted from Eugenia caryophyllata, Lavandula officinalis and Pelargonium graveolens on multidrug resistant isolates of Pseudomonas aeruginosa were investigated. The main constituents of clove, lavander and geranium oil were eugenol (80-90%), 1,8-cineol (13%) and citronellol (45%) respectively. Clove had the most ...
کنترل پشه‌ها و حفاظت افراد از گزش آنها یکی از مهمترین راه‌های پیشگیری از بیماریهای منتقله به‌وسیله آنها می‌باشد. گزش این حشرات علاوه بر ایجاد عوارض موضعی (خارش، قرمزی و سوزش) می‌تواند موجب انتقال بیماریهای مهلک و خطرناک به‌خصوص در مناطق حاره و گرمسیری گردد. یکی از روشهای کنترل این بیماری حفاظت افراد از گزش پشه‌های ناقل می‌باشد، استفاده از دورکننده‌ها به‌ویژه دورکننده‌های گیاهی از روشهای مناسب ب...
In this work we have checked the ability of the essential oils extracted from six different medicinal plants (Eugenia caryophyllata, Origanum vulgare, Rosmarinus officinalis, Lavandula officinalis, Melaleuca alternifolia, and Thymus vulgaris) to inhibit the growth of 18 bacterial type strains belonging to the 18 known species of the Burkholderia cepacia complex (Bcc). These bacteria are opportu...
