OBJECTIVE The aim of this study was to investigate the potential anticancer properties of a methanol extract of Rheum palmatum roots against diethylnitrosamine (DENA)-induced hepatocellular carcinoma (HCC) in rats and to characterize its phytoconstituents. METHODS HPLC-PDA-MS/MS was used to profile

Stilbene derivatives, the principal constituent of Rheum undulatum L., are known to have a wide range of biological activities, such as anti-allergic, anti-diabetic, antioxidant, and anti-inflammatory activities. A phytochemical study on the methanol extract of Korean rhubarb (R. undulatum L.) led

Protein tyrosine phosphatase 1B (PTP1B) is important in the regulation of metabolic diseases and has emerged as a promising signaling target. Previously, we reported the PTP1B inhibitory activity of Rheum undulatum (RU). In the present study, we investigated the metabolic regulatory effects of RU in

To investigate the effects of a compound (FF16), compatibility of Rhodiola crenulata, Cordyceps militaris, and Rheum palmatum, on insulin resistance. The results showed that FF16 significantly improved the insulin sensitivity through decreasing AUC values in insulin tolerance tests by 24.1%, 38.5%;

In order to study the effects of anthraquinone extract from Rheum officinale Bail on Macrobrachium rosenbergii under high temperature stress, freshwater prawns were randomly divided into five groups: a control group was fed with basal diet, and four treatment groups fed with basal diet supplemented

We evaluated the effect of dietary supplementation with anthraquinone extract (from Rheum officinale Bail) on the resistance to Aeromonas hydrophila infection in Megalobrama amblycephala. The fish were randomly divided into two groups: a control group (fed a standard diet) and a treatment group

Numerus studies highlighted benefits of natural flavonoids in the management of diabetes. The present study was aimed to investigate the effects of a high flavonoids containing extract of Rheum turkestanicum on diabetic changes in different tissues. Male Wistar rats were divided into normal and

Aloe-emodin is a natural anthraquinone compound from the root and rhizome of Rheum palmatum. In this study, KB cells were treated with 2.5, 5, 10, 20, and 40 microM aloe-emodin for 1 to 5 days. The results showed that aloe-emodin inhibited cancer cells in a dose-dependent manner. Treatment with

Aloe-emodin is a novel active compound found in the root and rhizome of Rheum palmatum. To investigate the effects and mechanisms of aloe-emodin on human gastric cancer, MGC-803 cells were treated with 2.5, 5, 10, 20 and 40 microM aloe-emodin for 1-5 d. The results showed that aloe-emodin inhibited

We screened water and methanol extracts of 28 Indonesian medicinal plants for their protein tyrosine phosphatase 1B (PTP1B) inhibitory activities. Nine water extracts, i.e., Alstonia scholaris leaf, Blumea balsamifera, Cinnamomum burmannii, Cymbopogon nardus, Melaleuca leucadendra, Phyllanthus

Emodin, an anthraquinone derivative isolated mainly from the root and rhizome of the medicinal plant Rheum palmatum L., was found to exert anticancer effects on various cultured cancer cells. Phosphatase of regenerating liver-3 (PRL-3), a novel gene, has been known to play an important role in the

The protective effects of anthraquinones from Rhubarb, a Chinese herbal medicine, consisting of the root and rhizome of Rheum palmatum L., R. tanguticum Maxim. Ex Balf., or R. officinale Baill. (family Polygonaceae) were investigated and compared in rats with liver injury induced by

OBJECTIVE The aim of this study was to investigate the effects of aloe-emodin, a natural compound from the root and rhizome of Rheum palmatum, on the growth of human cervical cancer cells, HeLa. METHODS HeLa cells were treated with various concentrations of aloe-emodin for 1-5 d, and cell growth was

UNASSIGNED Hyperhomocysteinemia (HHcy) is an independent risk factor for dementia, including Alzheimer's disease (AD). Lowering homocysteine levels with folic acid treatment with or without vitamin B12 was shown few clinical benefits on cognition. UNASSIGNED To verify the effect of emodin, a
