Streszczenie:

The chemical compositions of the hydrodistilled essential oils of ripen and unripen berries of Juniperus macrocarpa Sibth. & Sm. (Jom) were analysed by GC-MS. Thirty eight compounds were identified from unripe berries, accounting for approximately 0.03% oil yield (v/w dried weight) and 16 compounds from ripe berries with 0.003% oil yield (v/w dried weight). While the major compounds in the essential oils of unripe berries were α-cedrol (30.04%), α-pinene (18.81%), germacrene-D (14.58%), δ-cadinene (3.80%), γ-cadinene (2.29%), α-humulene (2.29%), γ-muurolene (2.27%), epi-bicyclosesquiphella

Terpenes contribute to the desirable flavour and aroma of grapes and wine. The biosynthesis of these plant secondary metabolites is influenced by both physiological and environmental factors, such as grapevine phenological stage and sunlight exposure. In this study, we investigated the influence of ultraviolet (UV) at different grapevine phenological stages on free terpenes in grape at harvest. Two types of transparent polymer films were applied to grape bunches to eliminate both UV-A and UV-B or only eliminate UV-B, followed by the identification and quantification of terpenes using headspace

The purpose of this study was to determine the chemical composition, physical properties, enantiomeric composition and cholinesterase inhibitory activity of the essential oil (EO) steam-distilled from the leaves of the plant Araucaria brasiliensis Loud. collected in Ecuador. The chemical composition was determined by gas chromatography coupled to mass spectrometry (GC-MS) analysis on two capillary GC columns (DB5-ms and HP-INNOWax). Thirty-three compounds were identified in the EO; the main compounds were beyerene (26.08%), kaurene (24.86%), myrcene (11.02%), α-pinene (9.99%) and 5,15-rosadien
