Nowadays, safety of chemical preservatives has been questioned by a big number of consumers. Traditionally used preservatives often cause skin irritation and lead to allergenic reactions. Growing demands for more natural and preservative-free cosmetics promoted an idea of the replacement of synthetic preservatives with essential oils (EOs) of antimicrobial properties. The antimicrobial effect o...

This study investigates the impact of seasonal variation on the chemical composition of essential oils from the leaves of Porcelia macrocarpa (Annonaceae) obtained over the course of one year (January-December 2011) and the chemical composition of the essential oils obtained from the ripe fruits of the same plant. Furthermore, the essential oils of the leaves were investigated with respect to t...

ETHNOPHARMACOLOGICAL RELEVANCE Schinus molle L. has been used in folk medicine as antibacterial, antiviral, topical antiseptic, antifungal, antioxidant, anti-inflammatory, anti-tumoural as well as antispasmodic and analgesic; however, there are few studies of pharmacological and toxicological properties of Schinus molle essential oils. The aim of this study was to evaluate the antioxidant and a...

the essential oils obtained from fresh fruits and terminal branchlets with adherent leaves of cupressus sempervirens l. cv. cereiformis rehd. growing in iran, were analyzed by gc-ms, and screened for bacteriostatic and fungistatic activities. thirteen components were identified in the essential oils. the main constituents of both fruits and leaves were ?-pinene, æ-3-carene, ?-terpenyl acetate a...

Background: The genus lagochilus, family Lamiaceae consists of 44 species, 33 of which grow in central Asia. Only one report on the analysis of essential oil of Lagochilus species has been published. Objective: Aim of this study is to determine the chemical composition and antimicrobial activities of the hydrodistilled oil of flower and leaves of Lagochilus kotschyanus Boiss. of Iranian origi...

Objective: To evaluate lipoxygenase inhibitory, antioxidant, and antimicrobial activities of selected essential oils. Materials and Methods: Essential oils were obtained by hydro distillation using a Clevenger-type apparatus and oils composition was analyzed by gas chromatography-mass spectrometry. Lipoxygenase inhibitory activity of essential oils was evaluated by lipoxygenase inhibition assay...

Essential oils are one of the most important natural products derived from plants, due to their various biological properties and their medicinal and nutritional uses. This chapter provides an overview of several different aspects relating to essential oils including a his‐ torical perspective, the uses of essential oils, their main sources and antifungal activity, their bioactive single consti...
