the essential oil from flowering aerial parts of nepeta macrosiphon boiss. growing wild in kermanshah province, iran, was analyzed by gc/ms. this essential oil was prepared by a modified likens-nickerson’s simultaneous distillation-extraction (sde) method. forty-five compounds consisting 95.1% of the total components were identified from the oil obtained with a yield of 0.1%w/w. among them, spa...

Kiwifruit vines rely on bees for pollen transfer between spatially separated male and female individuals and require synchronized flowering to ensure pollination. Volatile terpene compounds, which are important cues for insect pollinator attraction, were studied by dynamic headspace sampling in the major green-fleshed kiwifruit (Actinidia deliciosa) cultivar 'Hayward' and its male pollinator 'C...

Basil (O. gratissimum L) is a aromatic and medicinal plant widely used in traditional medicine in Morocco. The aim of this work was to study the effect of three plant growth regulators gibberellic acid (GA), indole 3-acetic acid (IAA) and benzylaminopurine (BAP) on the content and composition of essential oils of this plant, especially on the main compound (methyl chavicol) and its isomer (the ...

Myoporum sandwicense A. Gray (naio) is one of the characteristic trees Hawaiian montane–subalpine mesic forests. In this study, lab-distilled oils M. leaves, wood, and twigs growing on island Hawaii, as well industrially produced wood oils, were characterized by gas chromatography–mass spectrometry (GC-MS). The screened for antimicrobial activity. leaf essential oil was rich in β-caryophyllene ...

Michelia crassipes is a great ornamental plant, the flowers of which have high economic value. In this study, we employed headspace solid-phase microextraction (HS–SPME) combined with gas chromatography high-resolution mass spectrometry (GC–HRMS) for first time to identify volatile compounds emitted from different organs M. at flowering stages. flower odor comprises 69 that are dominated by ter...

The biodiversity found in Brazilian’s ecosystems brings the possibility of discovering new natural products with wide application potentials. However, knowing their availability and chemical composition is crucial. Thus, aim this study was to evaluate extraction yield, antioxidant activity essential oil from fresh leaves Calyptranthes concinna DC., a native species Myrtaceae occurring Brazilian...
