Petroleum ether extract major components were dominated by: 3,4-dihydrothienyl-5-carboxtthiol (1.9 %), acetic acid butyl ester (41.7 %), bicyclooct-2-ene-4卤, 6卤-carbolactone (6.1 %), 2-pentanone 4-hydroxy-4methyl (6.8 %), benzene 1, 4-dimethyl (4.9 %), 2-methyl-5-phenyl-5-...
It appeared that some spices could provide complementary nutrients which could improve the utilization of LQF where hay had better chemical composition than the other two forages. Cumin contained more crude protein (CP), ether extract and mineral contents whereas turmeric contained more soluble sugars...

However, the plant origin and the collection region can substantially affect the chemical composition of propolis25–34. The pharma- cological potential of propolis has been very well investigated and reported in the literature, as evidenced by the large number of related reports25–39. In vivo ...
However, studies have focused on the chemical composition of AGS and urine or protein carriers of putative pheromones [21, 22, 26, 30], but little is known about the synthesis of these odorants or the role of micobiota. The peri-anal area where these glands are found would appear to ...
The composition of the essential oil of the fresh whole Acmella radicans (Jacq.) R.K. Jansen var. radicans (Asteraceae) plant and two root-extracts from southern India were investigated by gas chromatographic–spectroscopic (GC-FID and GC-MS) and olfactive methods to identify those volatiles re...
. Moreover, the aerial parts’ essential oil composition evidenced the presence of numerous oxygenated monoterpenes and monoterpene hydrocarbons and represented interesting antioxidant and anti-inflammatory activities [15,16]. However, the roots’ chemical compositions as well as the potential health ...
