The bioassay-directed isolation of Terminalia chebula fruits afforded four human immunodeficiency virus type 1 (HIV-1) integrase inhibitors, gallic acid ( 1) and three galloyl glucoses ( 2 - 4). In addition, four flavonol glycoside gallates ( 5 - 8) from Euphorbia pekinensis containing the galloyl moiety also showed the inhibitory activity at a level comparable to those of 2 - 4.

Ethanolic extracts of 30 Thai medicinal plants, traditionally used as alternative treatments in diabetes, were evaluated for antioxidative activity by the 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) method. They were evaluated in vitro for oxidative stress by thiobarbituric acid-reactive substance (TBARS) assay in pooled plasma of diabetic patients compared to without treatment of the extracts (control). The extracts were also assayed for protein glycation. The results showed that five plants had strong antioxidant activity: Phyllanthus emblica Linn.

Quantification of bioactive principles through modern analytical tools is essential for establishing the authenticity, credibility, prescription and usage of Ayurvedic medicines/herbal formulations. 'Chyavanprash' is one of the oldest and most popular Ayurvedic preparations, used widely as a health promotive and disease preventive 'Rasayana' drug in India and elsewhere. The rejuvenating and tonic properties of 'Chavanprash' are considered mainly due to their antioxidant principles, which in turn is due to the presence of phenolic compounds.

The quality of botanical food is increasingly assessed by the content of multiple bioactive compounds. This study reports, for the first time, an HPLC fingerprinting method for the quality evaluation of Rubus suavissimus leaves possessing multiple bioactivities. Five constituents, gallic acid, rutin, ellagic acid, rubusoside, and steviol monoside, were quantified and used in developing qualitative chromatographic fingerprints. The limits of detection and quantification ranged from 0.29 to 37.86 mug/mL.

Susceptibility to inflammatory bowel diseases depends upon interactions between the genetics of the individual and induction of chronic mucosal inflammation. We hypothesized that administration of dietary phenolics, caffeic acid and rutin, would suppress upregulation of inflammatory markers and intestinal damage in a mouse model of colitis. Colitis was induced in C3H/ HeOuJ mice (8 weeks old, 6 male/6 female per treatment) with 1.25% dextran sulfate sodium (DSS) for 6 d in their drinking water.

Inflammatory bowel disease (IBD) can be divided into two major categories, ulcerative colitis (UC) and Crohn disease (CD). While the main cause(s) of IBD remain unknown, a number of interventional and preventive strategies have been proposed for use against CD and UC. Many reports have focused on the use of alternative natural medicines as potential therapeutic interventions in IBD patients with minimal side effects.

The complete and unambiguous (1)H NMR assignments of ten marker constituents of Ginkgo biloba are described. The comprehensive (1)H NMR profiles (fingerprints) of ginkgolide A, ginkgolide B, ginkgolide C, ginkgolide J, bilobalide, quercetin, kaempferol, isorhamnetin, isoquercetin, and rutin in DMSO-d(6) were obtained through the examination of 1D (1)H NMR and 2D (1)H,(1)H-COSY data, in combination with (1)H iterative full spin analysis (HiFSA).

Lymphedema may be presented in mild or less severe form. Nowadays, accurate diagnosis and effective therapy are available. Wearing surgical bandage, massage, exercise, and pumps form the core program for most patients with lymphedema. The application of pharmacological therapies has been notably absent from the management strategies for lymphatic vascular insufficiency states but lately some progress has been made by applying wobenzym in the treatment.

Quercetin, a flavonol contained in various vegetables and herbal medicines, has various biological activities including anti-cancer, anti-allergic and anti-oxidative activities. However, low oral bioavailability of quercetin due to insolubility in water has limited its use as a food additive or dietary supplement. Since the water solubility is enhanced by glycosyl conjugation, in the present study, we evaluated the bioavailability of several quercetin glycosides with different sugar moieties in rats.
