Food waste is one of the main topics various scientific studies last decade. In this regard, work analyzed an essential oil (EO) extracted from flavedo Citrus aurantium ‘Crispifolia’ fruit. The analysis, performed by GC-MS, showed a chemically variegated chromatogram characterized presence limonene (33.35%), but also oxygenated monoterpenes such as β-linalool (7.69%), α-terpineol (7.06%), and g...

Background and objectives: Dracocephalum kotschyi is a plant which belongs to the Lamiaceae family and exists mostly in south-west Asian countries, including Iran. This plant is used as antispasmodic, analgesic and anti-inflammatory to treat rheumatoid diseases. Methods: In order to investigate the impact of the harvesting time changes on the quantity and quality of monoand sesquiterpenoid comp...

Abstract This Short Review covers the total synthesis of tetraketide-based meroterpenoids, i.e. geranyl-resorcinols, isolated from mushrooms genus Hericium. Some these compounds are believed to be involved in unique health-promoting effects Hericium erinaceus. Herein, more than seventy natural products identified so far have been classified into seven-types based on both assumed biosynthetic pa...

Andrena, Mandibular Glands, Pheromone, Spiroacetals The complex volatile secretion from the mandibular glands of Andrena haemorrhoa (Hym., Apoidea) has been analysed by GC/MS. It is composed primarily of three groups of compounds: 1. Spiroacetals of five different systems: two l,6-dioxyspiro[4.4]nonanes, four l,6-dioxaspiro[4.5] decanes, two l,7-dioxaspiro[5.5]undecanes, one l,6-dioxaspiro[4.6]...

By implementing a common and industrially used method, 30 compounds which are structurally related to geranyl acetone, nerolidol, farnesal, farnesol and farnesyl acetate were obtained. Their antimicrobial activity against Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii bacteria was investigated. Pharmacophor...

      The composition of the essential oils of Nepeta crispa Willd. and N. menthoides Boiss. and Buhse (Lamiaceae) was investigated by means of gas chromatography (GC) and GC- mass spectrometery (MS). 1, 8-Cineole was the most abundant component in oils: Nepeta crispa (71%) and N. menthoides (41.1%). In the oil of N. crispa, b-pinene (5%) an...

The composition of the essential oil from leaves of Skimmia laureola was determined by GC and GC-MS. Twenty-eight components were identified, accounting for 93.9% of the total oil. The oil is mainly composed of monoterpenes (93.5%), of which monoterpene hydrocarbons and oxygenated monoterpenes represent 11.0% and 82.5%, respectively. Sesquiterpenes constitute only 0.3% of the total oil. Linalyl...

GC-MS/FID analysis of the essential oils 10 Thymus species, belonging to Sect. Serpyllum, led identification 118 compounds accounting for 97.79–99.69% total oil. moesiacus, T. jankae, vandasii, longicaulis and sibthorpii were characterized by presence linalool (19.37–35.21%) as major or dominant component, but differed significantly in content other prominent components: linalyl acetate, gerani...

This study evaluated the effects of caffeic acid and chlorogenic on chemical constituents lychee wine fermented with Saccharomyces cerevisiae DV10 when added at 200 mg/L 300 before fermentation. Results showed that addition had no effect ability alcoholic fermentation S. cerevisiae. The both acids decreased utilization amino nitrogen sources produced less α-ketoglutaric, succinic, acetic acid. ...
