Only registered users can translate articles

OBJECTIVE To determine sennoside A in rhubarb extracts by solvent extraction and SFE-CO2. METHODS Sennoside A was extracted by ultrasonic vibration. The analytical column was Allitima RP C18 (250 x 4.6 mm, 5 microm). The mobile phase consisted of 0.1% TFA-HCN (44:56). The flow rate was 1.0 ml/min.

The influence of rhein 8-O-β-D-glucopyranoside on the purgative action of sennoside A from rhubarb in mice.

Rhubarb is one of the most well-known herbal medicines that constitute daiokanzoto (DKT), which is clinically effective for constipation. Sennoside A is transformed into an active metabolite, rheinanthrone, by intestinal bacteria. Sennoside A in rhubarb showed significantly accelerated metabolic

Rheinanthrone, a metabolite of sennoside A, triggers macrophage activation to decrease aquaporin-3 expression in the colon, causing the laxative effect of rhubarb extract.

BACKGROUND Aquaporin-3 (AQP3) is expressed in mucosal epithelial cells in the colon and is important for regulating fecal water content. We examined the role of AQP3 in the laxative effect of rhubarb extract. METHODS After orally administering rhubarb extract or its major component (sennoside A) to

OBJECTIVE The aim of this study was to develop a method of removing sennoside to reduce the cathartic effect of rhubarb while conserving its other pharmacological activities. METHODS Rhubarb powder was steam autoclaved at 121°C and 0.14 MPa for 20, 60, or 120 minutes, and HPLC analysis was conducted

Study of various rhubarbs regarding the cathartic effect and endotoxin-induced disseminated intravascular coagulation.

Only registered users can translate articles

Sennoside A content in hot-water extracts from 17 varieties of rhubarb obtained from the market was measured, and their respective cathartic effects were also examined in mice. A positive correlation was confirmed between the sennoside A content and cathartic effects in our experiments. Furthermore,

[Comparative studies on purgative potency among three spieces of certified rhubarb].

Only registered users can translate articles

OBJECTIVE To investigate the difference and causes of purgative activity in three species of certified rhubarb, so as to lay steady foundations of further research on assessing purgative activity impersonally by using measurable indexes. METHODS The potencies of three species were comparied with

Development of eastern blotting technique for sennoside A and sennoside B using anti-sennoside A and anti-sennoside B monoclonal antibodies.

Only registered users can translate articles

BACKGROUND Rhubarb, senna and sennoside-containing preparations are currently widely employed as purgatives. The major active components of these medications are sennoside A (SA) and sennoside B (SB). OBJECTIVE To develop an eastern blotting technique for the specific visualisation and easy

High-performance liquid chromatographic determination and metabolic study of sennoside a in daiokanzoto by mouse intestinal bacteria.

Only registered users can translate articles

Daiokanzoto (DKT, combination of rhubarb and glycyrrhiza), a Kampo medicine, is clinically effective for constipation. Sennoside A is well known to induce diarrhea. Sennoside A is a prodrug that is transformed into an active metabolite, rheinanthrone, by intestinal bacteria. In this study, we

Simple and rapid analysis of sennoside A and sennoside B contained in crude drugs and crude drug products by solid-phase extraction and high-performance liquid chromatography.

Only registered users can translate articles

The sennoside A (SA) and sennoside B (SB) contents of various samples of crude drugs were determined using solid-phase extraction (SPE) and HPLC. The samples examined were crude drugs (senna leaf, senna pods, and rhubarb), conventional crude drug products, and Kampo formulations. The sample solution

Only registered users can translate articles

BACKGROUND Anthraquinones extract from Rheum palmatum L. (rhubarb) including rhein, emodin, aloe-emodin, chrysophanol, physcion and sennoside A, has been widely used in China to treat various diseases. OBJECTIVE This study was designed to explore the pharmacokinetic and pharmacodynamic properties of

Metabolism and mutual biotransformations of anthraquinones and anthrones in rhubarb by human intestinal flora using UPLC-Q-TOF/MS.

Only registered users can translate articles

Anthraquinones and anthrones are the main active components of rhubarb. To investigate the metabolism and possible mutual biotransformations pathways of anthraquinones and anthrones by human intestinal flora, 9 representative constituents (aloe-emodin, rhein, emodin, chrysophanol, physcion,

Gut Bacteria Selectively Altered by Sennoside A Alleviate Type 2 Diabetes and Obesity Traits

Only registered users can translate articles

Accumulating evidences implicate that gut microbiota play an important role in the onset and prolongation of fat inflammation and diabetes. Sennoside A, the main active ingredient of Rhizoma Rhei (rhubarb), is widely used for constipation as a kind of anthranoid laxative (e.g., senna). Here, we put

Identification of rhein as the metabolite responsible for toxicity of rhubarb anthraquinones

Only registered users can translate articles

Rhubarb is a popular food in Europe with laxative properties attributed to anthraquinones. Long term usage of rhubarb anthraquinones has been linked to colonic toxicity, including the formation of melanosis coli, which is associated with increased risk of colon cancer. The major purgative
