title: Antimicrobial Constituents of the Mature Carpels of Manglietiastrum sinicum.
abstract: Seven new compounds, including a eupodienone-type lignan (1), a dibenzocyclooctadiene-type lignan (2), three tetrahydrofuran-type lignans (3-5), and two 1-phenylbutyl benzoates (6, 7), together with six known compounds, were isolated from the mature carpels of Manglietiastrum sinicum. The structures of new compounds 1-7 were defined by spectroscopic techniques, and the absolute configuration of manglisin A (1) was determined by X-ray crystallography. Compounds 1-4 exhibited moderate antimicrobial activities (MIC values: 0.016-0.14 μM) against Staphylococcus aureus, MRSA 82(#), MRSA 92(#), MRSA 98(#), and MRSA 331(#). Compounds 2 and 3 showed weak cytotoxic activity against five human tumor cell lines.
