In the present study, silver nanoparticles (AgNPs) were synthesized by using aqueous root extracts of Rheum palmatum and characterized by various spectroscopic methods. The nanoparticles were found to be in hexagonal and spherical shapes. The average particle size was found to be 121 ± 2 nm with
Rheum palmatum L. (Chinese rhubarb) is a highly regarded medicinal plant. Its dominant active constituents are anthraquinones including emodin, aloe-emodin, rhein, etc. Rhein naturally occurs in anthraquinone (1, 3, 8-trihydroxy-6-methyl anthraquinone), which is found in R. palmatum L. and related
Entamoeba histolytica infects 50 million people worldwide and causes 55 thousand fatalities every year. Current anti-amebic drugs (e.g. paromomycin) work either at the level of the intestinal lumen (where trophozoites proliferate via cell divisions) or on the invasive trophozoites that have
Rheum palmatum L. is a traditional Chinese medicine with various pharmacological properties, including anti-inflammatory, antibacterial, and detoxification effects. In this study, the mechanism of the hypoglycemic effect of purified anthraquinone-Glycoside from Rheum palmatum L. (PAGR)
BACKGROUND
Kampos, commonly used in Japanese traditional medicine, are standardized herbal mixtures that have been used for centuries to treat a variety of ailments. We hypothesized that Kampos may have unidentified properties that may be beneficial in periodontitis, an inflammatory disease
BACKGROUND
Chitosan (AC) and five hydroalcoholic extracts from Lithospermum erythrorhizon (SE), Rheum palmatum (RE), Thymus vulgaris (AT), Lippia citriodora (PLX) and a mixture of Rosmarinus officinalis, Salvia lavandulifolia and Thymus mastichina (LA) were tested for antimicrobial activity against
OBJECTIVE
To screen some Chinese herbal medicines for their inhibitory activity on cariogenic bacteria, and investigate their active ingredients, and measure their minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC).
METHODS
Active components were isolated from every
The tetramic acid (2,4-pyrrolidinedione) scaffold has been recognized as an important structural feature because of its mycotoxic, antibacterial, antiviral, and antioxidant activities. This important class of natural products is reportedly produced by the type-I polyketide synthase/nonribosomal
Emodin (EMD) is an anthraquinone derivative extracted from the root and rhizome of Rheum palmatum L. which exhibits a range of activities, including anti-bacterial, antitumor, diuretic and vasorelaxant effects. The ability to inhibit metastasis and angiogenesis was shown in previous pharmacological
Traditional Chinese herbal medicine (TCHM) has been widely used in the treatment of chronic hepatitis B (CHB) in China. The systematic analysis of clinical research of TCHM against CHB revealed its potential but not confirmed its therapeutic effect. To understand the detailed antiviral effect of
OBJECTIVE
Emodin (3-methyl-1,6,8-trihydroxyanthraquinone) is one of the active components present in the root and rhizome of Rheum palmatum. It has been shown to contain biological activity (antitumour, antibacterial, diuretic and vasorelaxant effects). However, the mechanisms underlying the
Antimicrobial photodynamic therapy (aPDT) has received considerable attention as an emerging and promising approach for treating superficial infections. The aim of this study was to investigate aPDT mediated by aloe emodin (AE), a natural compound isolated from Aloe vera and Rheum Emodin is one of the main active ingredient of Rheum palmatum, and has anti-inflammatory, anti-bacterial, anti-viral and other effects. In recent years, it arouse concern since it has a significant anti-tumor effect with low toxicity. In this paper we mainly report the anti-cancer effects of emodin
