Licorice has been used as herbal medicine and natural sweetener. Here, we prepared Glycyrrhiza uralensis water extract (GUWE) and investigated the effect of GUWE on the maturation and function of dendritic cells (DCs) and its adjuvant effect on DC-based vaccine. We observed that GUWE dose-dependently promoted DC maturation and cytokine secretion through TLR4 signaling pathway. The capacity of D...

Two novel oleanane-type triterpene saponins, licorice-saponin P2 (1) and licorice-saponin Q2 (3), together with nine known compounds 2, 4-11, have been isolated from the water extract of the roots of Glycyrrhiza inflata. The structures of these compounds were elucidated on the basis of spectroscopic analysis, including 2D-NMR experiments (1H-1H COSY, HSQC, HMBC and ROESY). In in vitro assays, c...

Using a sequential in vitro/in vivo approach, we tested the ability of botanical extracts to influence biomarkers associated with bone resorption and bone formation. Pomegranate fruit and grape seed extracts were found to exhibit anti-resorptive activity by inhibiting receptor activator of nuclear factor-κB ligand (RANKL) expression in MG-63 cells and to reduce IL-1β-stimulated calvarial (45)Ca...

Molhuysen et al.(1950) demonstrated through their experiments that licorice extract causes retension of sodium and chloride as well as excretion of potassium, i. e. DOC-like action, in normal subjects. Groen et al.(1951), Card et al.(1953) and Calvert(1954) reported its therapeutic effects in Addison's disease or adrenocortical insufficiency.Thereafter glycyrrhizine has been shown to be the act...

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...

Coronary artery disease due to atherosclerosis is one of the highest killers today. Cholesterol level reduction by diet or medication would lead to either halting, or decreasing atherosclerosis. We examined whether Licorice root extract can halt atherosclerosis. Fifty male rabbits randomly were divided in five groups. They had gone under normal and high cholesterol (HC) diet for six weeks. One ...

This study aimed to assess the adjuvant effect of Montanide ™ ISA 763 AVG and Licorice extract (Glycyrrhiza glabra) on the immune responses and disease resistance of rainbow trout (Oncorhynchus mykiss) immunized with Formalin inactivated whole cells of Lactococcus garvieae vaccine. Rainbow trout with an average initial weight of 72±3 g were randomLy divided into four experimental treatments: no...

BACKGROUND Burn is still one of the most devastating injuries in emergency medicine while improvements in wound healing knowledge and technology have resulted into development of new dressings. This study was undertaken to evaluate the healing effect of licorice in Pseudomonas aeruginosa infected burn wounds of experimental rat model. METHODS One hundred and twenty female Sprague-Dawley rats ...

Licorice (Glycyrrhiza glabra L.) is an important medicinal plant. In this study, the antimicrobial activities of ethanolic and aqueous extracts from licorice leaves were studied compared to root extracts activities. Bacillus subtilis, Enterococcus faecalis, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli, and Candida albicans were used as test organisms...
