Abstract:
Flavonoid from Tan Cuong tea leaves (F.TC) exhibited anti-bacterial activity in vitro for the following 9 bacteria species and fungals: Staphylococcus aureus, E.coli, Salmonella typhi, Shigella flexneri, Pseudomanas aeruginosa, Klebsiela pneumoniae, Bacillus subtilis, Candida stellaloides, and Candida albicans. The best effect was observed in Staphylococcus aureus and the worst in Candida stellaloides, Candida albicans. The minimum inhibited levels of F.TC were different: Staphylococcus aureus and Salmonella typhi < (1/256 x 50 mg/ml); E.coli, Salmonella typhi, Shigella flexneri, Pseudomonas aeruginosa, Klebsiela pneumoniae (1/256 x 50 mg/ml). The dose: 1g/kg for oral; 0.1g/kg for subcutaneous injection; 0.1g/ml on the skin. Inhibitive rate of subcutaneous injection was 74.%> on the skin 58.% >oral route 38.%
