In the title compound, C(35)H(37)Cl(6)FO(14)·C(4)H(8)O(2)·H(2)O, the absolute configurations (1S,2S,3R,4S,5R,7S,8S,10R,13S) for the nine chiral centres of the mol-ecule has been determined. In the crystal, mol-ecules are linked by O-H⋯O and O-H⋯Cl hydrogen bonds.
rosa damascena has been found to act on central nervous system including the brain. several studies confirm that r. damascena inhibits the activity of the hypothalamus and pituitary systems in rat and can suppress the central nervous system. in traditional medicine hypnotic effect of rose is also suggested. in this study, the hypnotic effect of the ethanol crude extract of r. damascena and its ...
background: salvia limbata is an aromatic herbaceous plant and grows widely in iran turkey and afghanistan. in the previous study, six flavones together with rosmarinic acid were isolated from the ethyl acetate and methanol extracts of s. limbata. in this report, we focused on the isolation and identification of the glycosylated sterols and the main accumulated amino acid of the species s. limb...
The title compound, C7H11N3O2S, exists in the 5-thioxo tautomeric form. The 1,2,4-triazoline ring is essentially planar, with a maximum deviation of 0.010 (2) Å for the substituted N atom. The ethyl acetate substituent is almost planar, with a maximum deviation of 0.061 (4) Å for the methyl-ene C atom of the eth-oxy group. The angle between the mean plane of this substituent and the mean plane ...
The title compound, [PtCl(2)(C(20)H(20)P)(2)]·C(4)H(8)O(2), crystallizes with the Pt atom in a distorted cis-square-planar geometry. The Pt-P bond lengths are 2.2490 (19) and 2.253 (2) Å, and the Pt-Cl bond lengths are 2.344 (2) and 2.3475 (18) Å. Some weak C-H⋯Cl and C-H⋯O inter-actions involving the solvate mol-ecule were observed.
This study shows the impact of three different commercial inactive yeast derivatives (IYDs) (Opti Less™, Noblesse™, Optimum White™, Lallemand, Canada and Oenolees MP™ Lafort, USA) during 6-month aging period on volatile profile, sensory attributes antiradical activity, including polyphenols total free sulfhydryl (-SH groups) content, Grašac wines made in sequential fermentation with native Hans...
This research aimed to investigate the phytoconstituents and antibacterial effects of methanol ethyl acetate stem bark extracts Detarium microcarpum (DM). The phytochemicals were detected quantified while activity against Escherichia coli, Staphylococcus aureus, Salmonella typhi was established determining zone inhibition (ZI), minimum inhibitory concentration (MIC), bactericidal (MBC). Phytoch...
