The aqueous extracts of twenty plants were screened by agar diffusion methods for their antibacterial activity against Rathyibacter tritici, a causal organism of tundu diseases of wheat. The combined extracts of leaf extracts of Datura stramonium and stem extracts of Acacia catechu in general showed a strong enhancement in activities over the individual extracts of leaves extracts of Datura str...

The current study was aimed at investigating the effect of Areca catechu nut dichloromethane fraction (7 mg/kg) on monoamines (serotonin and dopamine) modulation (5-hydroxytryptophan-induced tremors and phenylethylamine-induced stereotypes) and its interaction with tyramine (cheese effect). The dichloromethane fraction caused pronounced increase in 5-HTP-induced tremors (50%) with negligible PE...

The husk fibres of Areca catechu (areca nut) are reported to be used by the people of rural areas of Dakshina Kannada, Karnataka for cleaning their teeth. The beneficial effects of these plant materials are not scientifically proven, so the study was carried out to estimate the antimicrobial properties of A.catechu against common oral pathogens. These antimicrobial properties in addition to mec...

Background and objectives: Alzheimer’s disease (AD) is characterized as the most prevalent age related neurodegenerative disease along with cognitive impairment in elderly people. Most of therapeutic treatments for AD have dedicated to the inhibition of cholinesterase (ChEs) to increase the level of acetylcholine (ACh) in the cholinergic synaptic cleft. Acetylcholinesterase (AC...

The attractive colours and fragrance produced by the plants is due to specific phytochemicals present in them. They may be tannins, flavonoids, glycosides, saponins, steroids and alkaloids. Emblica officinalis, Acacia catechu, Acacia concina and Hibiscus rosa-sinensis, are medicinal dye yielding plants belong to different families. The qualitative analysis carried out for these plants showed th...

The methanol extracts of nine medicinal plants traditionally used in Chinese medicine were screened for antioxidant activity versus resveratrol, which has been shown to protect cells from oxidative damage [Toxicol. Lett. 102 (1998) 5]. Most of the plant extracts used in this study inhibited the H(2)O(2)-induced apoptosis of Chinese hamster lung fibroblast (V79-4) cells. The extracts of Areca ca...

Oral cancer is in approximately 30% of all cancers in India. This study was conducted to evaluate the cytotoxic activity of ethanolic extract of Acacia catechu bark (ACB) against human squamous cell carcinoma cell line-25 (SCC-25). Cytotoxic effect of ACB extract was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium Bromide assay. A. catechu extract was treated SCC-25 cells wit...

The germination percentage of Acacia catechu Willd. seeds were tested with four pre-sowing treatments in the nursery of Bangladesh Forest Research Institute and growth performances of seedlings were determined both in nursery and field conditions. The germination test was conducted both in germination tray and nursery bed filled with mixture of soil and decomposed cow dung at a ratio of 3:1. Th...

Flavonoids, from Scutellaria baicalensis (Chinese skullcap) and Acacia catechu (black catechu), have been shown to exert a variety of therapeutic effects, including anti-inflammatory, antiviral, antibacterial, and anticancer activities. Flavocoxid is a mixed extract containing baicalin and catechin and it acts as a dual balanced inhibitor of cyclooxygenase-1 (COX-1) and COX-2 peroxidase enzyme ...
