[Anti-HBsAg herbs employing ELISA technique]

With the aid of the ELISA system this schema represented a laboratory approach to the recognition of anti-HBsAg capability of herbs by using 300 herbal extracts. Altogether 10 herbs (3.0%) were identified as effective. When forming a multiplex plan by employing 10 average P/N ratios as exemplified by 5 varying doses of herb (0.3, 0.6, 1.2, 2.5, 5.0 mg/100 microliters), 2 varying concentrations of HBsAg (10.92, 14.26 P/N ratio), and 3 varying contact time periods (immediate, 1h, 2h) for the comprehensive appraisal of herb efficacy index, these 10 effective herbs were listed in the following order: Prunella vulgaris (1.00), Litchi chinensis (1.26), Gossypium herbaceum (1.45), Cudrania cochinochinensis (1.56), Caesalpinia sappan (1.73), Oldenlandia tenelliflora (1.77), Cautis parthenocissus (1.99), Evodia rutaecarpa (2.01), Portulaca grandiflora (2.44), and Anemone hupehensis (2.83).
