glycyrrhetic acid/glycyrrhiza

The objective of this paper was to develop a preparative method for the isolation and purification of liquiritigenin and glycyrrhetic acid from Glycyrrhiza uralensis Fisch using hydrolytic extraction combined with high-speed countercurrent chromatography (HSCCC). Liquiritigenin and glycyrrhetic acid

OBJECTIVE To extract microRNA(miRNA) from Glycyrrhiza uralensis(liquorice) decoction and to explore its effect on mmune cells. METHODS With dried processed liquorice, the water decoction was prepared according to the conventional method and subsequently concentrated by rotary evaporation. The

Glycosides including triterpenoid saponins and flavonoid glycosides are the main constituents of Glycyrrhiza uralensis Fisch (licorice) and exhibit prominent pharmacological activities. However, conventional methods for the separation of glycosides always cause irreversible adsorption and

To clarify the feasibility of medicinal use of the cultivated Glycyrrhiza resources, the equivalency between the G. uralensis roots cultivated in eastern Nei-Meng-Gu of China and medicinal licorice (Glycyrrhizae Radix, Gancao in Chinese and Kanzo in Japanese) was examined. The HPLC fingerprint

BACKGROUND Glycyrrhiza uralensis Fisch. and processed radix Aconiti kusnezoffii are the main components in many Chinese traditional patent medicines with the ratio of 1:1, which are used for treatment of rheumatoid arthritis, heart failure and so on. Glycyrrhizic acid, glycyrrhetic acid,

Glycyrrhizic acid (GL) is a major active compound of licorice. The specific monoclonal antibody (MAb) (designated as 8F8A8H42H7) against GL was produced with the immunogen GL-BSA conjugate. The dissociation constant (Kd) value of the MAb was approximately 9.96x10(-10) M. The cross reactivity of the

OBJECTIVE To set up the quantitative method of herberine in decoctions prepared from various combinations of Maxingganshi decotion by HPLC and to determine the change of general contents in different decoction. METHODS The study was designed by L8 (2(7)) orthogonal and to determine the change of

Two sweet oleanane-type triterpene oligoglycosides named apioglycyrrhizin and araboglycyrrhizin were isolated from the air-dried roots of Glycyrrhiza inflata Batalin, collected in Xinjiang province (Shinkyo-Kanzo in Japanese), together with glycyrrhizin (3), licorice-saponins A3 (8), G2 (10), and H2

Glycyrrhizin (GZ) and licorice (root of Glycyrrhiza uralensis) are worldwide food additives and important oriental phytomedicines. This study investigated the biological fate of GZ by orally giving GZ and licorice decoction (LD) to rats. The serum concentrations of GZ and glycyrrhetic acid (GA) were

An ultra-performance liquid chromatography quadrupole time of flight mass spectrometry (UPLC-qTOF-MS/MS) method was developed and validated for the simultaneous determination of glycyrrhizin and glycyrrhetic acid. These analytes were separated on a reverse phase C18 column using a mobile phase of

The differences in gastrointestinal absorption behaviors of glycyrrhizin (GZ) between pure GZ and GZ in glycyrrhiza extract (GE) (equivalent dose as GZ) were examined in rats. Similarly to the case of pure GZ, both GZ and glycyrrhetic acid (GA) were detected in the plasma after oral administration

A HP20 resin-based unique method was adopted to get an active fraction of the hydroalcoholic extract of G. glabra roots. The fraction showed potent cytotoxicity against cancer cell line and was further subjected to detailed phytochemical investigation to obtain ten biomarkers. The isolated

Liquorice (root of Glycyrrhiza uralensis FISCH) is an ingredient of candies and used as a popular medicine in Europe and oriental countries. Cyclosporine (CsA), an immunosuppressant with narrow therapeutic window, is widely used in transplant patients. The absorption and disposition of CsA were
