Antimicrobial Activity of the Essential Oil of Phlomis Bracteosa
The essential oil was isolated from the aerial parts of Phlomis bracteosa Royle ex Benth., a hairy erect herb. The leaves and flowers of this species are used as carminative, stimulant and locally known as ‘Ballikotu, Calba, Salba’ in Turkish traditional medicine. The antimicrobial activity of Phlomis bracteosa was studied using well diffusion method. The activity was tested against human patho...
متن کاملAnalysis of the Fatty acid Composition of Phlomis bracteosa oil by Gas Chromatography - mass spectrometer
The Phlomis bracteosa oil constituents of methyl ester derivatives of fatty acids were analyzed using Gas Chromatography coupled to mass spectrometer. The results obtained containing the saturated as well as unsaturated fatty acids of P. bracteosa oils. A total of 18 different components were identified and quantified. Methyl ester of octadecadienoic acid was found in high concentration 6.88 %,...
متن کاملVasodilator effect of Phlomis bracteosa constituents is mediated through dual endothelium-dependent and endothelium-independent pathways.
This study describes the vasorelaxant potential of some pure compounds isolated from Phlomis bracteosa L. marrubiin, phlomeoic acid, and two new constituents labeled as RA and RB. In rat thoracic aortic rings denuded of endothelium, marrubiin, phlomeoic acid, RA, and RB caused relaxation of high K(+) (80 mM) and phenylephrine (1 μM)-induced contractions at the concentration range of 1.0-1000 μg...
متن کاملPhlomisflavosides A and B, new flavonol bisglycosides from Phlomis spinidens.
From the aerial parts of Phlomis spinidens, two new flavonol bisglycosides, phlomisflavosides A (1) and B (2), were isolated together with the known compounds, astragalin, isoquercitrin, lamiridoside, phlomoside A, shanzhiside methyl ester, 8-O-acetylshanzhiside methyl ester, phlorigidoside C, rodioloside (=salidroside), forsythoside B, citroside A and lariciresinol-4'-O-beta-D-glucoside. The s...
متن کاملPhysocalycoside, a new phenylethanoid glycoside from Phlomis physocalyx Hub.-Mor.
A new phenylethanoid tetraglycoside, physocalycoside (2), was isolated from the aerial parts of Phlomis physocalyx. Its structure was identified as 3-hydroxy-4-methoxy-beta-phenylethoxy-O-[alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-rhamnopyranosyl-(1-->3)]-4-O-feruloyl-[beta-D-glucopyranosyl-(1-->6)]-beta-D-glucopyranoside, on the basis of spectroscopic evidence. In addition, one known iridoid glu...
