Fungi release wide spectrum of volatile organic compounds (VOCs) that belong to several chemical groups with different biochemical origins such as monoterpenes, sesquiterpenes, alcohols, aldehydes, aromatic compounds, esters, furans, ketones, sulfur and nitrogen compounds. Trichoderma species are the most studied fungal biocontrol agents and are successfully used as biofungicides and biofertili...

Obesity, defined as New World Syndrome, causes global health problems and big economic losses. Natural products have gained increasing importance because of their antiobesity potency. The genus Jurinea Cass. with approximately 200 described species worldwide has been traditionally used a therapeutic agent for colic, fever, gout rheumatism. aim this study was to analyze the volatile components, ...

This study aimed to determine the essential oil volatile components of ginger and turmeric rhizomes, as well total antioxidant capacity samples according CUPric Reducing Antioxidant Capacity (CUPRAC), ferric reducing potential (FRAP) method free radical scavenging activities standards such BHA, BHT, Trolox were determined using a DPPH method. Essential analysis was also performed on Shimadzu GC...

background and objectives: essential oils are very complex mixture of components and their composition may vary in different species or varieties or even within the same variety. origanum vulgare l. subsp. vulgare is one of the most distributed subspecies within the genus origanum and has been found to be a poor-oil, categorized in cymyl, bornane or sabinyl chemotypes with higher proportion of ...

Herbivores emit volatile organic compounds (VOCs) after feeding on plants. Parasitoids exploit these VOCs as odor cues to locate their hosts. In nature, host-related odors are emitted as blends of various compounds occurring in different proportions, and minor blend components can sometimes have profound effects on parasitoid responses. In a previous related study, we identified and quantified ...

Constitutive and induced terpenoids are important defense compounds for many plants against potential herbivores and pathogens. In Norway spruce (Picea abies L. Karst), treatment with methyl jasmonate induces complex chemical and biochemical terpenoid defense responses associated with traumatic resin duct development in stems and volatile terpenoid emissions in needles. The cloning of (+)-3-car...
