a review of the publications in traditional medicine indicates that the root of glycyrrhiza glabra l., fabaceae, is recommended for treatment of epilepsy. as a renewable source, the leaves of g. glabra var. glandulifera growing in iran were examined for possible anticonvulsant activity. the anticonvulsant activity of the leaves’ ethanol extract and dichloromethane, f1, n-hexane, f1a, and methan...

From the ethanolic extract of the roots of Cassia multijuga two anthraquinones C15H10O4 (Qi) and C16H12O6 (Q2) and two anthraquinone glycosides C28H32O15 (Si) and C27H30O14 (S2) have been isolated. Homogeneity and purity of these compounds were established by chromatography. Anthraquinone (Qi) has been identified to be 1:3-dihydroxy-2-methyl anthraquinone (rubiadin) by standard colour reactions...

In this paper, we demonstrate a novel carbon nanotube (CNT) reinforced macroporous adsorption resin (MAR) for the first time. The CNTs were dispersed in water via sonication, and then in situ physically entrapped in the pores of MAR by capillary forces and sonication. The resulting CNT reinforced MAR (CNT-MAR) was proved by transmission electron microscopy (TEM) and confocal laser scanning micr...

BACKGROUND Severe asthma is associated with T helper (TH) 2 and 17 cell activation, airway neutrophilia and phosphoinositide-3-kinase (PI3K) activation. Asthma exacerbations are commonly caused by rhinovirus (RV) and also associated with PI3K-driven inflammation. Anthraquinone derivatives have been shown to reduce PI3K-mediated AKT phosphorylation in-vitro. OBJECTIVE To determine the anti-inf...

An ethanol extract of rhubarb rhizome exhibited marked glucose transport activity in differentiated L6 rat myotubes. Activity-guided fractionation resulted in the isolation of two anthraquinones, chrysophanol-8-O-beta-D-glucopyranoside (1) and chrysophanol (2). The anti-diabetic effect was examined by glucose transport activity, glucose transporter 4 (Glut4) expression in myotubes, and the leve...

We studied the effects of aqueous, chloroform, and ethanol extracts of Aloe vera gel on carrageenan-induced edema in the rat paw, and neutrophil migration into the peritoneal cavity stimulated by carrageenan. We also studied the capacity of the aqueous extract to inhibit cyclooxygenase activity. The aqueous and chloroform extracts decreased the edema induced in the hind-paw and the number of ne...

The genus Cassia is comprised of ten species of yellow, flowering ornamental trees of the Fabaceae (Press et al., 2000). Cassia fistula L., locally known as “rajbriksha” in Nepal, is a deciduous tree native to East India, Nepal, Burma, and Malaysia (Press et al., 2000). Traditionally in Nepal, the plant’s fruit pulp is used as an antipyretic (Gewali, 2008), it is also used to treat habitual con...
