background: salvia limbata is an aromatic herbaceous plant and grows widely in iran turkey and afghanistan. in the previous study, six flavones together with rosmarinic acid were isolated from the ethyl acetate and methanol extracts of s. limbata. in this report, we focused on the isolation and identification of the glycosylated sterols and the main accumulated amino acid of the species s. limb...

objectives this study was designed to determine the chemical composition, in vitro antioxidant activity, and total phenol content of various extracts of s. chloroleuca. materials and methods dried aerial parts of the plant were crushed, then sequentially extracted with n-hexane, ethyl acetate, and methanol. the fractions of s. chloroleuca were subjected to silica gel column chromatography and s...

BACKGROUND Leakage of the intestinal mucosal barrier may cause translocation of bacteria, then leading to multiorgan failure. This study hypothesized that rhubarb monomers might protect the gut mucosal barrier in sepsis through junction proteins. METHODS Healthy male Sprague-Dawley rats (weighing 230-250 g) under anesthesia and sedation were subjected to cecal ligation and perforation (CLP). ...

The different extracts of the roots of Helicteres isora (Family-Sterculiaceae) were tested for anti-diabetic activity, by glucose tolerance test in normal rats and alloxan induced diabetic rats. Aqueous ethanol and butanol extracts had shown significant protection and lowered the blood glucose levels to normal in glucose tolerance test. In alloxan induced diabetic rats the maximum reduction in ...

General phytochemical screening of the aqueous extract of fruits of Solanum xanthocarpum (Solanaceae) revealed the presence of steroids, terpenes, phenolic compounds, saponins, fatty acids, alkaloids. Fractionation of aqueous extract and activity guided isolation resulted in isolation of two white crystalline powder which were subjected to physical, chemical and spectral identification using IR...

Zhejiang provinces of China. The roots of this plant are used as a remedy for icterus and arthritis in Chinese folk medicine. Hitherto, no chemical constituents or bioactivities of this plant have been reported. In the course of our search for active components from this plant, three new phenolics, (1S,2R)-1-(4 -O-b -D-glucopyranosyl-3 -methoxyphenyl)-2(4 -hydroxy-3 -methoxyphenyl)-1,3-propaned...

Allergic inflammation is induced by allergens and leads to various allergic diseases, including rhinitis, asthma and conjunctivitis. Histamine is important in the pathogenesis of an immunoglobulin E‐dependent allergic reaction and results in the secretion of cytokines associated with inflammation. Angelica dahurica (A. dahurica) is a medicinal plant widely used in China for the treatment of sym...

Objective—To test the hypothesis whether herbal medicines ameliorate inflammatory diseases via the modulation of cellular adhesion molecules (CAMs). Methods—Human neutrophils, synovial fibroblasts, and endothelial cells were incubated with diVerent concentrations of Tripterygium Wilfordii Hook-f (TWH-f) or Tetrandrine in the presence or absence of interleukin 1 (IL1). The amount of soluble E-se...
