Two new lignans from Phyllanthus amarus.
Two new lignans, 3-(3,4-dimethoxy-benzyl)-4-(7-methoxy-benzo[1,3]dioxol-5-yl-methyl)-dihydrofuran-2-one (1) and 4-(3,4-dimethoxy-phenyl)-1-(7-methoxy-benzo[1,3]dioxol-5-yl)-2,3-bis-methoxymethyl-butan-1-ol (2), were isolated from the leaves of Phyllanthus amarus and their structures were established by spectral analysis. Additionally, eight known lignans were also isolated and characterized.
