Phenylpropanoids from Brachybotrys paridiformis maxim. Ex oliv. And their anti-HBV activities (II).

Five undescribed phenylpropanoids, one undescribed phenolic glucoside, and sixteen known compounds were isolated from Brachybotrys paridiformis Maxim. Ex Oliv. The undescribed compounds were named brachoside B-C, brach acid A-B, brachnan A, and brachin D, respectively. Additionally, the anti-hepatitis B virus activities of all isolated compounds were studied. Among them, brachnan A, brach acid A, globoidnan A, 3-carboxy-6,7-dihydroxy-1-(3',4'-dihydroxy-phenyl)-naphthalene, and 3,4-dihydroxybenzaldehyde showed significant anti-hepatitis B virus activities.
