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 paper focuses on the in vitro antimicrobial activity of Lavandula angustifolia Mill. (lavender) essential oil in combination with four commercial antimicrobial agents. Stock solutions of chloramphenicol, ciprofloxacin, nystatin, and fusidic acid were tested in combination with L. angustifolia essential oil. The antimicrobial activities of the combinations were investigated against the Gram-...
The antioxidant activity of five samples of Lavandulae flowers (L. angustifolia ssp. angustifolia, L. hybrida, L. angustifolia spp. pyrenaica, L. angustifolia spp. angustifolia cv. Munstead and cv. Hidicote Blue) harvested from Romania was investigated using DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging and ferrous ion chelating assays. Total polyphenolic content (mg/g dried extract) ...
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,...
The present research was planned to characterize the aroma composition of important members of the Lamiaceae family such as Salvia officinalis, Lavandula angustifolia and Mentha asiatica. Aroma components of the S. officinalis, L. angustifolia and M. asiatica were extracted with the purge and trap technique with dichloromethane and analyzed with the gas chromatography-mass spectrometry (GC-MS) ...
Essential oil components were extracted from Lavandula angustifolia (Lavender) flowers using pressurized fluid extraction (PFE). A Box-Behnken design was used to optimize the effective extraction variables. The chemical composition of extracted samples was analyzed by gas chromatograph-flame ionization detector column. For achieving maximum % extraction yield the temperature, pressure, and dyna...
The definition of the volatile organic compounds profile plants is an important tool for food quality and authenticity assessment. aim this study was to quantitative determination three Artemisia campestris L. subsp. glutinosa, Lavandula angustifolia Mill., Zingiber officinale rosch. using Gas Chromatography-Mass Spectrometry (SPME/GC-MS). Thirty-three were determined in application SPME/GC-MS....
کنترل پشه ها و حفاظت افراد از گزش آنها یکی از مهمترین راه های پیشگیری از بیماریهای منتقله به وسیله آنها می باشد. گزش این حشرات علاوه بر ایجاد عوارض موضعی (خارش، قرمزی و سوزش) می تواند موجب انتقال بیماریهای مهلک و خطرناک به خصوص در مناطق حاره و گرمسیری گردد. یکی از روشهای کنترل این بیماری حفاظت افراد از گزش پشه های ناقل می باشد، استفاده از دورکننده ها به ویژه دورکننده های گیاهی از روشهای مناسب ب...
