Objective: The antiulcer activity of various extracts of Hibiscus rosa sinensis leaves was evaluated in pyloric ligation induced gastric ulcer in albino rats. Method: The leaves extracts were prepared by cold maceration process with petroleum ether, alcohol and water separately. Results: Oral administration of aqueous and alcohol extracts (200 and 400 mg/kg) of Hibiscus rosa sinensis leaves wer...
The volatile compounds of wines made from three grape varieties (Monastrell, Cabernet Sauvignon and Syrah) using three pre-fermentation techniques (grape freezing, dry-ice and cold maceration) and a control treatment were measured. The different winemaking practices, which are intended to increase the aromatic properties of wines, produced results that depended on the variety concerned. For exa...
Cabernet Sauvignon, Malbec and Merlot grapes were processed with prefermentative cold soak (CS) for 5 days followed by a short maceration time of (CS + 5d), or long 10 10d). CS did not affect the basic chemistry wines, nor improved anthocyanins, polymeric pigments total phenolics relative to Control wines (10 maceration). Wine tannins lowered in 5d 71 % (Cabernet Sauvignon) 29 (Merlot). CIELab ...
background & aim: the purpose of present study was to examine and validate the folk's claim of inhalation of monechma ciliatum seeds powder by traditional african natives for cold and allergic conditions, so as to formulate a useful therapeutic agent to respiratory tract infections. experimental: different extracts were bio-assayed in vitro for their bioactivity to inhibit the growth of pat...
The purpose of this study is to identify the oily and non-polar compounds Onopardum acanthium emerged in south IRAQ prepare them for further biological chemical once their identity was affirmed. extraction done using cold maceration with petroleum ether solvent. After that, extracts send chromatographic analysis characterize present extract.
The efficacy of decoction in extracting mycobactericidal compounds from Flourensia cernua (Hojasé) leaves and fractionation with solvents having ascending polarity was compared with that of (i) ethanol extraction by still maceration, extraction with a Soxhlet device, shake-assisted maceration, or ultrasound-assisted maceration, followed by fractionation with n-hexane, ethyl acetate, and n-butan...
