Six neolignans including three previously undescribed metabolites: 1-[(7R)-hydroxy-8-propenyl]-3-[3'-methoxy-1'-(8'-propenyl)-phenoxy]-4,5-dimethoxybenzene, 4-hydroxy-5-methoxy-3-[3'-methoxy-1'-(8'-propenyl)phenoxy]-1-(7-oxo-8-propenyl)benzene and
Eight undescribed neolignans and an undescribed propanoid dimer were isolated from the leaves of Miliusa sessilis, together with two known compounds, dehydrodieugenol A and dehydrodieugenol B. All structures were elucidated by extensive spectroscopic data analysis and the structure of
