Parasitoids employ different types of host-related volatile signals for foraging and host-location. Host-related volatile signals can be plant-based, originate from the herbivore host or produced from an interaction between herbivores and their plant host. In order to investigate potential sex- and species-related differences in the antennal response of parasitoids to different host-related vol...

The present study investigates the aroma, key odorants and sensory profile of extra virgin olive oils from five well-known Turkish cultivars. aromatic extract obtained by purge trap extraction system, according to a analysis, resembled odor oil. A total 22, 21, 18, 22 21 aroma-active compounds were detected in extracts Ayvalık, Memecik, Gemlik, Sarı Ulak Beylik oils, respectively. results show ...

Globba macrocarpa Gagnep. is a rare species of genus (Zingiberaceae family). The present study reported the chemical compositions and antibacterial effects acetone extracts obtained from G. rhizomes aerial parts. By using Gas Chromatography Mass Spectrometry (GC/MS) assay, fifty thirty-two compounds were identified parts species, respectively. Of those, germacrene D (15.25 %), 1H-indole, 4-(3-m...

Background Anthriscus caucalis is a non-native plant in North America with invasive potential. As part of our interests essential oils the Great Basin, wild-growing sample A. was collected southwestern Idaho. Methods The obtained by hydrodistillation and analyzed gas chromatographic methods (GC–MS, GC–FID, chiral GC–MS). Results major components oil were cis-chrysanthenyl acetate (42.3%), myrce...

To explore whether preputial gland secretions and/or urine from the house mouse (Mus musculus) can be used for coding information about sex, individuality, and/or the genetic background of strain [ICR/albino, Kunming (KM), and C57BL/6], we compared the volatile compositions of mouse preputial glands and urine using a combination of dichloromethane extraction and gas chromatography coupled with ...

Phytochemical analysis of the leaf extract Zanthoxylum caribaeum Lam (Family Rutaceae) collected in La Garita district, Municipality Los Patios Norte de Santander, Colombia, is reported. Ethanolic extracts by simple maceration were concentrated at reduced pressure. Secondary metabolites found preliminary identification demonstrated presence alkaloids, tannins, carotenoids, anthocyanins, coumari...

Jujube seed oil is pressed by Ziziphi Spinosae Semen，and widely cultivated in China with healthful. Here, we focused on illustrating the components and antioxidant activity of oil. The was analyzed GC-MS. vitro tested free radical scavenging. vivo using Saccharomyces cerevisiae model. results GC-MS showed that alkenes (e.g., d-limonene α-farnesene) were richest jujube experiments suggested poss...

This study evaluates the content of essential oils (EOs) and prenylated flavonoid Xanthohumol (XN) in extracts Slovenian hops, cultivar Aurora, obtained by using fluids different polarity. It is a continuation our previous work, investigating extraction bitter acids from hops. Extraction was conducted semi-continuously, sub- supercritical polarity, i.e., carbon dioxide (CO2) propane as non-pola...
