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...

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...

The genus Hypericum is one of the most important medicinal plants that contain 17 species in Iran, three of them are endemics. This paper reports the essential oil composition of six Hypericum species from Iran. The essential oil analysis of a number of the studied plants has already been reported but their report from Iran may be valuable for scientists.  Samples collected between June and Aug...

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 ...

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...

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...
