Using an HBV‐producing cell line and inhibition of the expression of the HBsAg and HBeAg as antiviral indicators, a study was conducted on 25 compounds isolated from four Phyllanthus (Euphorbiaceae) plants, including P. amarus Schum. & Thonn., P. multiorus Willd., P. tenellus Roxb. and P. virgatus Forst. f.. It was found that niranthin ( 1 ), nirtetralin ( 3 ), hinokinin ( 5 ) and geraniin ( 13 ) at the non‐cytotoxic concentration of 50 µ m , suppressed effectively both HBsAg and HBeAg expression, with the highest inhibition at 74.3%, 45.3%; 69.6%, 33.9%; 68.1%, 52.3%; 32.1%, 46.6%, respectively. Of these, niranthin ( 1 ) showed the best anti‐HBsAg activity, while the most potent anti‐HBeAg activity was observed with hinokinin ( 5 ). Copyright © 2003 John Wiley & Sons, Ltd.
