The main aim of this study was to enrich glycyrrhizic acid ammonium salt known as one of the main compounds of licorice roots (Glycyrrhiza glabra L.) by isoelectric focused adsorptive bubble separation technique with different foaming agents. In the experiments, four bubble separation parameters were used with β-lactoglobulin, albumin bovine, and starch (soluble) preferred as foaming agents and...

a high performance liquid chromatography method was studied for determination of 18 ?-glycyrrhetinic acid in glycyrrhiza glabra l. (licorice) extract. the operating condition were c-18 reversed phase column (vp-ods, (250×4.6 mm, 5 mm)) at room temperature, acetonitril/phosphoric acid (3/1) as mobile phase, at flow rate of 0.6ml/min (0-8min), 0.4ml/min (8-20min) and uv detection at 230 nm. the r...

Introduction: Glycyrrhiza glabra (Licorice) has been traditionally used as a medicinal plant in Iran for treatment of diseases such as gastric ulcer and arthrosclerosis. In this study, in order to determine some of its mechanisms, effects of hydroalcoholic extract of Glycyrrhiza glabra was examined on the blood pressure in rats. Methods: Adult male rats were anesthetized via injection of pen...

vasomotor hot flash is the most common and distressful complication of menopausal women. its treatment is the most frequent clinical challenge. as a result, an effective and harmless therapy is needed. this double-blind controlled clinical trial was conducted to determine the effects of licorice roots on the relief and recurrence of hot flash in menopausal women referring to the healthcare cent...

Background and Aim: Oral infections and dental caries are considered as two serious public health problems, which inflict a costly burden on health care services worldwide, especially in the developing countries. The aim of this study was to evaluate the antibacterial activity of Iranian Licorice aqueous root extract on Lactobacillus Acidophilus in comparison with Chlorhexidine. Material...
