Antimutagenicity of water and chloroform extracts of dried myroblan Terminalia chebula was determined against two direct acting mutagens, sodium azide and 4-nitro-o-phenylenediamine (NPD) in strains TA100 and TA1535, and TA97a and TA98 of Salmonella typhimurium respectively and S9-dependent mutagen 2-aminofluorene (2-AF) in TA97a, TA98 and TA100 strains. Water extract reduced NPD as well as 2-AF induced his+ revertants significantly but did not have any perceptible effect against sodium azide included his+ revertants in TA100 and TA1535 strains of S. typhimurium.

A study to evaluate an antimutagenic potential of water, chloroform and acetone extracts of Triphala has been made in an Ames histidine reversion assay using TA98 and TA100 tester strains of Salmonella typhimurium against the direct-acting mutagens, 4-nitro-o-phenylenediamine (NPD) and sodium azide, and the indirect-acting promutagen, 2-aminofluorene (2AF), in the presence of phenobarbitone-induced rat hepatic S9. A combination drug 'Triphala' - a composite mixture of Terminalia bellerica, T.

In search of broad-spectrum antibacterial activity from traditionally used Indian medicinal plants, 66 ethanolic plant extracts were screened against nine different bacteria. Of these, 39 extracts demonstrated activity against six or more test bacteria. Twelve extracts showing broad-spectrum activity were tested against specific multidrug-resistant (MDR) bacteria, methicillin-resistant Staphylococcus aureus (MRSA) and extended spectrum beta-lactamases (ESbetaL)-producing enteric bacteria.

The fruit of Terminalia chebula Retz. (T. chebula), which is a member of the Combfreetaceae family, is used widely in Asian countries as a traditional folk medicine, and its extract has been reported to be an anticancer, antidiabetic and anticaries agent. In our previous study, chebulic acid isolated from T. chebula extract was confirmed to show antioxidant activity and protective action against endothelial cell dysfunction. In order to support the safety-in-use of the ethyl acetate (EtOAc)-soluble portion of a T.

ETHNOPHARMACOLOGICAL RELEVANCE: The decoction of Terminalia chebula fruit is an ayurvedic remedy whose prolonged oral administration is prized as a generic intestinal and hepatic detoxifying agent. Its administration is suggested also under the perspective of a reduced risk of cancer, metabolic and cardiovascular diseases. AIM OF THE STUDY: To evaluate the phytochemical profile and the chemopreventive potential of Terminalia chebula fruit decoction prepared according to the ayurvedic decoction recipe.

It is well documented that reactive oxygen species (ROS) are involved in the aetiology of age related diseases. Over the last decades, strong efforts have been made to identify antioxidants in human foods and numerous promising compounds have been detected which are used for the production of supplements and functional foods. The present paper describes the advantages and limitations of methods which are currently used for the identification of antioxidants. Numerous in vitro methods are available which are easy to perform and largely used in screening trials.

Essential oils from Melaleuca alternifolia (tea-tree oil) and Lavandula angustifolia (lavender oil) are commonly used to treat minor health problems. Tea-tree oil possesses broad-spectrum antimicrobial activity, and is increasingly used for skin problems. Lavender oil, traditionally used as an antiseptic agent, is now predominantly used as a relaxant, carminative, and sedative in aromatherapy. Despite their growing use no data are available on their mutagenic potential.

Associations of plants have been widely used, for centuries, in Ayurveda and in Chinese medicine and have been increasingly acknowledged in Western medicine. The objective of this study is to assess the level of toxicity of an association of three plants: Crataegus oxyacantha, Passiflora incarnata, and Valeriana officinalis (CPV extract). This association was administered to rats, mice, and dogs, both acute and chronically for 180 days. The tests used in the acute experiments were: observational pharmacological screening, LD(50), motor coordination and motor activity.

Terminalia arjuna is an important medicinal plants widely used in the preparation of Ayurvedic formulations used against several ailments. The present investigation was aimed at the fractionation of crude extracts from the bark of T. arjuna in order to isolate and purify the antimutagenic factors present. The antimutagenicity assay was performed to check the modulatory effect of these fractions against NPD, sodium azide, and 2AF, using the Ames Salmonella his+ reversion assay.

Salacia oblonga has been used for thousands of years in Ayurvedic medicine for the oral treatment of diabetes. The root extract has been shown to inhibit the activity of intestinal alpha-glucosidases, therefore S. oblonga holds potential as a natural method to mitigate the blood glucose response for people with diabetes. As part of a safety evaluation of novel ingredients for use in blood glucose control, the potential genotoxicity of a S.
