This investigation aims to assess the chemical composition and antioxidant properties of Origanum vulgare var. aureum L. essential oil (OEO). The was obtained with a 0.34% (v/w dried weight) yield investigated by gas chromatography-mass spectrometry (GC–MS) analysis. main compounds OEO were found be gamma-terpinene (22.96%), para-cymene (14.72%), germacrene (11.64%), beta-trans-ocimene (9.81%),...

In this study, Melaleuca alternifolia (Maiden and Betche) Cheel (tea tree) oil C. sinensis (L.) Osbeck (orange) was procured, their chemical compositions were characterized by gas chromatography coupled with mass spectrometry, co-injection using authentic samples. The oils rich in monoterpene hydrocarbons making up 84.5% of 48.9% M. oils. High amounts oxygenated monoterpenoids also identified (...

Redbay ambrosia beetle, Xyleborus glabratus Eichhoff, is a native of Southeast Asia recently established in coastal forests of Georgia, SC and Florida. It vectors a wilt fungus, Raffaelea sp., lethal to redbay trees, Persea borbonia L. Spreng, and certain other Lauraceae. No practical monitoring system exists for this beetle so we conducted studies to identify host attractants and develop lures...

BACKGROUND In the altiplano of Northern Chile the plant Senecio nutans is habitually used as an infusion to relieve the effects of altitude sickness (locally known as "puna"). It is also used to alleviate the bronchitis, whooping cough, asthma, stomachache, tiredness and fever. The extreme conditions under which these plant grow and scientific data that shows the inhibiting potential of the ess...

Hydro-distilled volatile oil from the aerial parts of Chenopodium ambrosioides L. (Chenopodiaceae) was obtained and the oil was analyzed by a combination of GC and GC/MS. Air-dried aerial parts of Chenopodium ambrosioides (100 g) which were collected from Anzaly in Mazandaran province at full flowering stage on June 2003, were subjected to hydro-distillation for 3.5 h using a Clevenger-type app...

Background: Summer savory (Satureja hortensis L.) is one of the most important medicinal and spice plants cultivated in many parts of the world. Objective: A greenhouse experiment was conducted to study the effects of FeSO4 and citric acid application on the morphological traits and essential oil content and its component, gamma-terpinene in S. hortensis. Methods: FeSO4 in four levels (0, 3, ...
