Turpentine is a volatile component of resin, which is an abundant forest resource in Southern China. As one of the most important components, the integrated application of β-pinene has been studied. The broad-spectrum evaluation of β-pinene and its analogues has, therefore, been necessary. In an attempt to expand the scope of agro-activity trials, the preparation and the evaluation of the herbi...

Pinene is an active natural monoterpene from plants and has important applications in flavorings, fragrances,and pesticides. Especially, pinene dimers are regarded as renewable fuels with high density. However, the microbial production was limited by low activity synthase. In this study, synthase improved fusion linker optimization chaperon coexpression. To construct pathway Saccharomyces cerev...

Aromas and fragrances can be obtained through the microbial oxidation of monoterpenes. Many microorganisms can be used to carry out extremely specific conversions using substrates of low commercial value. However, for many species, these substrates are highly toxic, consequently inhibiting their metabolism. In this work, the conversion ability of Aspergillus niger IOC-3913 for terpenic compound...

Heat stress resistance of foliar photosynthetic apparatus was investigated in the Mediterranean monoterpene-emitting evergreen sclerophyll species Quercus ilex. Leaf feeding with fosmidomycin, which is a specific inhibitor of the chloroplastic isoprenoid synthesis pathway, essentially stopped monoterpene emission and resulted in the decrease of the optimum temperature of photosynthetic electron...

Biogenic volatile organic compounds (BVOC) emissions from bioenergy crops may differ from those of conventional crops. We compared emission rates of isoprene and a number of monoterpenes from the lignocellulosic bioenergy crops short-rotation coppice (SRC) willow and Miscanthus, with the conventional crops wheat and oilseed rape. BVOC emission rates were measured via dynamic vegetation enclosur...

The aim of this research was to determine the chemical constituents and bioactivity of the essential oil derived from Alpinia galanga (L.) Willd. rhizomes against the cigarette beetle Lasioderma serricorne (F.) (Coleoptera Anobiidae) adults. The essential oil of A. galanga obtained by hydrodistillation was investigated by gas chromatography-mass spectrometry (GC-MS). The main components of the ...

The preparation of bioactive derivatives from the renewable natural product pinene is a hot research topic in deep processing and utilization pinene. In this study, β-pinene was used to develop novel molecules as promising new precursor insecticide. A series amide-containing were synthesized characterized. insecticidal activities these against Mythimna separate Semiaphis heraclei tested. struct...

The aim of this study was to determine the volatile components Helichrysum arenarium (L.) Moench subsp. aucheri that belongs genus, belonging Asteraceae family, one important families for Turkey and generally known as ‘ölmez çiçek, altın otu or mantuvar’ in Turkey. To components, leaves flowers specimens were collected from Isparta Aksu Adana Feke villages Turkey, dried at room temperature. The...
