Screening of various plant extracts used in ayurvedic medicine for inhibitory effects on human immunodeficiency virus type 1 (HIV‐1) protease
One of them, arecatannin B1 showed significant HIV‐1‐PR inhibitory activity and was shown by the A. catechu extract, from which some procyanidins were isolated. Expand
Antioxidative effects of phenylethanoids from Cistanche deserticola.
The acetone-H2O (9:1) extract from the stem of Cistanche deserticola showed a strong free radical scavenging activity and the antioxidative effect was found to be potentiated by an increase in the number of phenolic hydroxyl groups in the molecule. Expand
Four di-O-caffeoyl quinic acid derivatives from propolis. Potent hepatoprotective activity in experimental liver injury models.
The water extract of propolis showed a strong hepatoprotective activity against CCl4-toxicity in rats and D-galactosamine (GalN)/lipopolysaccharide (LPS)-induced liver injury in mice and four dicaffeoyl quinic acid derivatives from the PWE were isolated. Expand
Anti-inflammatory effects of emodin from ventilago leiocarpa.
Emodin, a major component of the AcOEt and CHCl3 fractions from Ventilago leiocarpa Bunge (Rhamnaceae), was isolated. It exhibited apti-inflammatory effect on carrageenan-induced edema in rats.
Inhibitory effects of Egyptian folk medicines on human immunodeficiency virus (HIV) reverse transcriptase.
The stereochemistry of 1 was established in this paper by nuclear magnetic resonance spectroscopy and was non-competitive with respect to the substrate but competitive withrespect to a template-primer. Expand

Salvia deserta SCHANG. (Lamiaceae) is a plant grown in Xinjiang province in China, and its dried roots are called Xinjiang-Danshen. This plant has not been used as a medicine or a food, but recentlyExpand
Hepatoprotective effect of Hovenia dulcis THUNB. on experimental liver injuries induced by carbon tetrachloride or D-galactosamine/lipopolysaccharide.
The methanol extract showed significant hepatoprotective activity against CCl4-toxicity in rats and D-galactosamine (D-GalN)/lipopolysaccharide-induced liver injury in mice. Expand
A purgative action of barbaloin is induced by Eubacterium sp. strain BAR, a human intestinal anaerobe, capable of transforming barbaloin to aloe-emodin anthrone.
Factors indicate that barbaloin is inactive as a laxative itself but is activated to aloe-emodin anthrone, a genuine purgative component, by Eubacterium sp. Expand
Anti-herpes simplex virus activity of moronic acid purified from Rhus javanica in vitro and in vivo.
Moronic acid showed oral therapeutic efficacy in HSV-infected mice and possessed novel anti-HSV activity that was consistent with that of the extract, which suppressed virus yields in the brain more efficiently than those in the skin. Expand
Antiviral traditional medicines against herpes simplex virus (HSV-1), poliovirus, and measles virus in vitro and their therapeutic efficacies for HSV-1 infection in mice.
12 HW-extracts, currently used for the treatment of various diseases other than viral infection, were found to be significantly effective in limiting the development of skin lesions and/or in prolonging the mean survival times of HSV-1-infected mice. Expand
