Monoterpenes contribute to the characteristic aroma of several hop varieties and may occur as nonvolatile glycosides. Upon hydrolysis, the volatile terpenes are released from the glycoside precursors. Little is known, however, about the glycoside composition of hops.

The microbiome of the digestive tract of ruminants contains microbial ecosystem that is affected by both environmental and genetic factors. The subject of this study concerns the influence of selected genetic factors, such as species of animals and “host” individual differences on the digestive tract microbiome composition.

The aim of the present research was to investigate the chemical composition, antioxidant and anti-tumor effects of Cordia dichotoma fruit pulp extract “CDFP-extract”. Day after intraperitoneal inoculation of Ehrlich ascites carcinoma (EAC) cells in mice, CDFP-extract was administered orally at 500 mg/kg body weight (equal to 0.10 of determined LD50) for ten consecutive days.

The fruits of Arbutus unedo L., a shrub that grows spontaneously in countries around the Mediterranean basin, are traditionally harvested and used for the production of a distilled spirit. The main objective of this work is to compare the chemical profile of distillates obtained from fermented A. unedo fruits. Fifteen distinct distillates were obtained from ten clones and five seedlings, and they were evaluated, based on their physicochemical characteristics.

In the present work, the volatiles of mosses [Hylocomium splendens (Hedw.) Schimp. (Hylocomiaceae) and Leucodon sciuroides (Hedw.) Schw¨agr. (Leucodontaceae)] have been investigated by GC-FID and GC/MS. Fifty-eight compounds in the oil of H. splendens, representing 75.4%, and 41 compounds in the oil of L. sciuroides, representing 87.6%, were identified. The major components were found to be β -pinene (11.6%) and α-pinene (8.9%) in the oil of H. splendens, and nonanal (26.8%) and heptanal (13.7%) in the oil of L. sciuroides.

The volatile components of essential oil (EO), SPME, and SPME of solvent extracts (n-hexane, methanol, and water) obtained from fresh Serapias orientalis subsp. orientalis(Soo) were analyzed by GC-FID/MS. EO of Soo gave 11 compounds in the percentage of 99.97%; capronaldehyde (37.01%), 2-(E)-hexenal (23.19%), and n-nonanal (19.05%) were found to be major constituents. SPME GC-FID/MS analyses of fresh plant and solvent extracts of Soo revealed 7, 12, 7, and 4 compounds within the range of 99.7% to 99.9%. Limonene (76.5%, 41.7%, and 61.

Aroma is one the most crucial inherent quality attributes of fruit. ‘Ruixue’ apples were selected from a cross between ‘Pink Lady’ and ‘Fuji’, a later ripening yellow new cultivar. However, there is little known about the content and composition of aroma compounds in ‘Ruixue’ apples or the genetic characters of ‘Ruixue’ and its parents.

The present paper describes chemical composition, NO inhibitory activity against lipopolysaccharide (LPS)-induced nitric oxide release, cytotoxic activity against MCF7 and Hep3B cell lines of the essential oil of Globba pendula Roxb. rhizomes. A total of 25 components of the essential oil were identified by using gas chromatography–mass spectrometry (GC-MS), accounting for 89.55 % of the total oil. -selinen (36.45 %) and ishwarane (10.76 %) were the main components.

Particle size is important parameter affecting the composition, quality and final applications of the producer gas. Fine grained or fluffy feed stock may cause flow problems in the gasifier as well as an inadmissible pressure drop over the reduction zone and a high proportion of dust in the gas. To avoid such problems briquetted material considered for gasification. The developed gasifier was tested with different sizes of briquettes of 15, 30 and 45 mm width and 90 mm diameter. The volatile matter, fixed carbon and ash content of briquette were found as 71.87%, 17.07% and 4.
