Purpose: To investigate the effect of different soil textures on chemical composition and antioxidant properties essential oils from Solanum nigrum.
 Methods: Four soils differing texture were formulated under fallow to cultivate S. nigrum in a glasshouse. Essential Oil was extracted fresh shoots by solvent-free microwave extraction (SFME) analysed using gas chromatography-mass spec...

The flower industry depends on oil and fragrance, which is addressed in the current work. Different concentrations of NaCl (0, 250, 500, 1000, 1500 ppm) were applied to Taif rose plants (Rosa damascena var. trigintipetala Dieck) evaluate their effects growth essential content. Results clearly indicated highest survival percentage (98.3%) was seen untreated compared under salinity stress. Moreov...

Multiple positive effects that forests have on human health and overall well-being been reported widely in the literature. Still, multiple elements of this relationship remain unidentified unexplained. In study, composition leaf volatile organic compounds (BVOCs) content three common coniferous species: Austrian pine (Pinus nigra), Scots sylvestris) Spruce (Picea abies), was analyzed. The speci...

Volatile organic compounds (VOCs) from uninfested and infested broccoli plant samples with green peach aphid Myzus persicae were investigated by headspace solid microextraction (HS-SPME) combined gas chromatography mass spectrometry (GC-MS). Overall, 25 identified in plants. The HS-SPME GC-MS analysis of the volatiles described differences between samples. Based on peak area analysis, VOCs sign...

Natural antioxidants (NAs) are promising substances, which established as potent therapeutic agents. However, the anticancer potential of many them is not completely known. In this research, effect three natural including geraniol (Ge), citronellol (Cit), and quercetin (Qu), their combination by estimating cytotoxicity on Hela cells at doses from 15.625 to 1000 µg/mL was investigated. Moreover,...

BACKGROUND The currently used fragrance mix in the European baseline patch test series (baseline series) fails to detect a substantial number of clinically relevant fragrance allergies. OBJECTIVE To investigate whether it is justified to include hydroxyisohexyl 3-cyclohexene carboxaldehyde (Lyral) and fragrance mix 2 containing hydroxyisohexyl 3-cyclohexene carboxaldehyde, citral, farnesol, c...

The orange-yellow and colorless essential oils with respective yields of 1.54% 3.59% were extracted from the dry leaves Cymbopogoncitratus (DC.) Stapf Eucalyptus citriodora Hook. collected south Brazzaville. Analysis by gas chromatography (GC) coupled mass spectrometry (GC/MS) allowed identification fifteen (15) eight (8) constituents representing (96.25%) (98.46%) total respectively. oil consi...

Aroma is one of the most important indicators grape quality. Girdling and foliar fertilization with K (K2O) are common agronomic practices applied to improve berry quality in production. However, little known about its effect on accumulation biosynthesis entire aromatic profile. Our study was aimed explore influences girdling (alone or combination) general properties, phenolic composition, vola...
