Ethanolic extracts and some fractions from 10 Indian medicinal plants, known for antibacterial activity, were investigated for their ability to inhibit clinical isolates of beta-lactamase producing methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive S. aureus (MSSA). Synergistic interaction of plant extracts with certain antibiotics was also evaluated. The MRSA test strains were found to be multi-drug resistant and also exhibited high level of resistance to common beta-lactam antibiotics.

Antioxidant activity of ethanolic extract of fruits of Terminalia chebula (500 mg/kg body wt, orally for 30 days) against isoproterenol-induced oxidative stress was investigated in rats. The levels of serum lipid peroxides, iron, ascorbic acid, vitamin E, plasma iron-binding capacity, and the activities of ceruloplasmin and glutathione were assayed, in addition to the activities of the antioxidant enzymes--glutathione peroxidase, glutathione reductase, glutathione-S-transferase, superoxide dismutase and catalase in the heart tissue.

The petroleum ether (PE), chloroform (CH), ethanol (ETH) and water extracts of Terminalia bellerica and T. chebula fruits were evaluated for their analgesic activity using the tail immersion model in mice. The ethanolic extracts of both the plants exhibited analgesic response at 200,400 and 800mg/kg. The studies were further carried for 15 days to evaluate the effect of these extracts in chronic pain and maximum analgesic response was observed on 14th day in both the plants. Phytochemical investigation of ethanolic extract of the fruits of Terminalia bellerica and T.

The in vitro study of the antioxidant properties of the hydroalcoholic extracts of various Indian medicinal plants can logically help to develop a better and safer way of amelioration from oxidative stress. As aimed, the present study has been done to estimate and thereby conclude regarding the antioxidant activities of a few Indian medicinal plants, viz., Terminalia chebula, Terminalia belerica, Emblica officinalis, Caesalpinia crista, Cajanus cajan, and Tinospora cordifolia.

In continuation of our drug discovery program on Indian medicinal plants, the gastro protective mechanism of chebulinic acid isolated from Terminalia chebula fruit was investigated. Chebulinic acid was evaluated against cold restraint (CRU), aspirin (AS), alcohol (AL) and pyloric ligation (PL) induced gastric ulcer models in rats. Potential anti-ulcer activity of chebulinic acid was observed against CRU (62.9%), AS (55.3%), AL (80.67%) and PL (66.63%) induced ulcer models.

AIMS: In this study, an attempt has been made to isolate and identify the bioactive compounds from hydroalcoholic extract of Terminalia chebula fruits effective against multidrug-resistant uropathogens and also to elucidate the influence of metal ions on the growth inhibitory activity of isolated compounds against the studied bacteria, if any. METHODS AND RESULTS: Bioassay-guided fractionation and extensive spectrometric analyses (FT-IR, (1) H NMR, (13) C NMR and ESI-MS) were used to isolate and characterize the bioactive compound.

CONTEXT: Arthritis is inflammation of one or more joints. Terminalia chebula Retz. (Combretaceae) fruit is mentioned in Ayurveda as useful in treating arthritic disorders. OBJECTIVE: This work was undertaken to evaluate the anti-inflammatory, antioxidant, anti-lipid peroxidative and membrane-stabilizing effects of hydroalcoholic extract of Terminalia chebula fruits and also to establish a possible association between them. MATERIALS AND METHODS: In vivo anti-inflammatory activity of T. chebula fruit extract at different doses ranged from 50 to 500?mg/kg, p.o.

"Triphala", the Ayurvedic wonder is used traditionally for the treatment of different types of diseases since antiquity. The hydroalcoholic extracts of the three components of Triphala powder demonstrated varying degrees of strain specific antibacterial activity against multidrug-resistant uropathogenic bacteria. Terminalia chebula fruit extract was active against all the test isolates followed by Terminalia belerica and Emblica officinalis.

The extracts from Chinese herbs are complex compounds with uncertain mechanism, which affects the target with all ingredients. Therefore, it is of great importance to evaluate the bioactivity of these extracts. In this study, 29 samples which had continuous variation of constituents were obtained from the alcohol extract of Terminalia chebula Retz. by a Sephadex LH-20 size exclusion chromatographic column.

AIM: Many weapons are available in the arsenal of a dental professional to combat dental caries, which is almost ubiquitously present. From a public health perspective, most of these weapons are far from being an ideal drug. Hence, there is a demand for better and effective antibacterial agents. This factor stimulated the process of the present study. The aim of the study was to determine the effect of ethanol extract of Terminalia chebula on Streptococcus mutans. MATERIALS AND METHODS: Dried ripe fruits of Terminalia chebula were procured and powdered.
