The vasorelaxant activity of marrubenol and marrubiin from Marrubium vulgare.
Crude extracts of the aerial parts of Marrubium vulgare show a potent in vitro inhibition of KCl-induced contraction of rat aorta. Bio-guided fractionations, spectroscopic analysis and chemical derivatization revealed the furanic labdane diterpenes marrubenol and marrubiin as the most active compounds.
متن کاملChromatographic Fingerprint Analysis of Marrubiin in Marrubium vulgare L. via HPTLC Technique.
PURPOSE In the present study we aimed to quantify marrubiin, as the major active compound, in the aerial parts of Marrubium vulgare from Iran using a HPTLC-densitometry technique. METHODS Quantitative determination of marrubiin in M. vulgare methanol extract was performed by HPTLC analysis via a fully automated TLC scanner. Later on, the in vitro antioxidant activity of the M. vulgare methano...

متن کاملSupercritical CO2 Extraction of Ethanol
Extraction of ethanol was studied from both synthetic ethanol solution and fermentation broth using supercritical CO2 in an extraction apparatus in ranges of 313 to 333 K and 80 to 160 atmospheres, for varying extraction times. The experimental system consists mainly of four parts: a CO 2 storage system, a high-pressure liquid pump, an extractor and a product collection unit. Samples were analy...
متن کاملOptimization of Extraction Conditions of Some Phenolic Compounds from White Horehound (Marrubium vulgare L.) Leaves
This research was aimed to optimize the extraction conditions of three phenolic compounds: total phenolics, flavonoids and condensed tannins, from White Horehound’s leaves (Marrubium vulgare L.). Distilled water and different organic solvents such as: methanol, ethanol and acetone, were used, with various concentrations (20% 80%, v/v), temperatures (20 ̊C 60 ̊C) and extraction times (30 450 min)....
