The aqueous extract of galls from Terminalia chebula Retz. (Combretaceae) was fractionated on Diaion and refractionated on octadecyl silica column. Six phenolic compounds were isolated and identified as gallic acid (1), punicalagin (2), isoterchebulin (3), 1,3,6-tri-O-galloyl-?-D-glucopyranose (4), chebulagic acid (5) and chebulinic acid (6). All of the compounds showed stronger 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging and melanin inhibitory activities than ascorbic acid, butylated hydroxytoluene, ?-tocopherol, arbutin and kojic acid, the reference compounds.

OBJECTIVES: To investigate transdermal absorption enhancement of gel containing elastic niosomes loaded with gallic acid in the semipurified fraction isolated from Terminalia chebula Retz. (Combretaceae) galls. MATERIALS AND METHODS: Nonelastic and elastic niosomes loaded with gallic acid in pure form or in the semipurified fraction were developed. Rat skin permeation by vertical Franz diffusion cells of gallic acid from various gel formulations containing elastic niosomes loaded with gallic acid or the semipurified fraction was performed.

CONTEXT: The galls of Terminalia chebula Retz. (Combretaceae) frequently appear in many Thai Lanna medicinal plant recipes for promotion of longevity. OBJECTIVE: The objective of this study was to evaluate the skin anti-aging of gel containing niosomes loaded with a semi-purified fraction containing gallic acid from T. chebula galls. METHOD: The semi-purified fraction containing phenolic compounds including gallic acid isolated from T.

BACKGROUND: Free radicals are implicated in several metabolic diseases and the antioxidant therapy has gained an utmost importance in the treatment. The medicinal properties of plants have been investigated and explored for their potent antioxidant activities to counteract metabolic disorders. In this study, the chemical composition and free radical scavenging potential of leaf gall extracts (ethanol, petroleum ether, chloroform and aqueous) of Terminelia chebula is evaluated, which is extensively used in the preparation of traditiona medications to treat various metabolic diseases.

BACKGROUND AND OBJECTIVES: A number of bacteria have now become antibiotic-resistant. This increases the importance of ayurvedic drugs. We report, here, the activity of different extracts (petroleum ether, chloroform, methanol and water) of Quercus infectoria galls against dental pathogens -- Streptococcus mutans, Streptococcus salivarius, Staphylococcus aureus, Lactobacillus acidophilus (designated) and Streptococcus sanguis (isolated). MATERIALS AND METHODS: The cup-plate method was used in anti-bacterial activity of the extracts at concentration of 200 mg/ml against dental pathogens.
