This work combined a micromorphological and phytochemical study approach on Lavandula angustifolia Mill. cultivated at the Ghirardi Botanic Garden (Toscolano Maderno, BS, Italy). The observations leaves flowers revealed occurrence of three trichome morphotypes: peltate, short- medium-stalked capitate. histochemical dyes evidenced huge production terpenes by peltate capitates, while short-stalke...

abstract: chemical composition of lavandula angustifolia was studied by solvent free microwave extraction (sfme) and hydrodistillation (hd) methods. 1, 8-cineole (42.7% and 37.9%), camphor (26.1% and 21.3%) and borneol (31.2% and 21.6%) were the major compounds that obtained by sfme and hydrodistillation, respectively. the antibacterial activity of extracted oils was investigated against gram-p...

Myrtle (Myrtus communis L.) is an important medicinal plant, of which all parts have pharmaceutical and nutritional applications distributed throughout the southwest regions Iran. The aerial myrtle were collected at different phenological stages (vegetative, flowering, unripe fruit ripening stages, after fully mature dispersal stage) from Fars Province Iran analyzed with GC–FID GC–MS. All data ...

The cattle tick Rhipicephalus microplus is one of the most important ectoparasites for livestock in tropical and subtropical areas worldwide. This hurts economy milk meat production chain. In addition, it constitutes a vector transmission Anaplasmosis Babesiosis pathogens. control R. populations mainly based on use synthetic acaricides. However, using this method presents danger to humans envir...

Plant essential oils are widely used as fragrances and flavours in the cosmetic, perfume, drug and food industries. Oxygenated monoterpenes are widespread components of the essential oils, usually occurring in high amount. In this paper, the antibacterial activities of twenty-one oxygenated monoterpenes (borneol, borneol acetate, camphor, carvone, 1,8-cineole, citronellal, beta-citronellol, dih...

Essential oils obtained by hydrodistillation from the different parts (stems, adult leaves, immature flowers and fruits) of Eucalyptus oleosa were screened for their antioxidant and antimicrobial properties and their chemical composition. According to GC-FID and GC-MS, the principal compound of the stem, immature flowers and the fruit oils was 1,8-cineole, representing 31.5%, 47.0% and 29.1%, r...

A protocol for the micropropagation of Eucalyptus polybractea R.T. Baker (blue mallee) using axillary bud proliferation from lignotuber-derived explants is described. Three different ages of plants were used as explant sources: glasshouse-grown seedlings, field-grown saplings, and coppice of field-grown mature lignotubers. Explants from each source initiated successfully and no significant diff...

Lavender (Lavandula angustifolia Mill.) is one of the most widely grown essential oil crops in the world. Commercial extraction of lavender oil is done using steam distillation. The objective of this study was to evaluate the effect of the length of the distillation time (DT) on lavender essential oil yield and composition when extracted from dried flowers. Therefore, the following distillation...

GC-MS analyses of nocturnal and diurnal floral volatiles from nine tobacco species (Nicotiana; Solanaceae) resulted in the identification of 125 volatiles, including mono- and sesquiterpenoids, benzenoid and aliphatic alcohols, aldehydes and esters. Fragrance chemistry was species-specific during nocturnal emissions, whereas odors emitted diurnally were less distinct. All species emitted greate...
