| 摘要 | (7S,8R,7'S)-9,7',9'-Trihydroxy-3,4-methylenedioxy-3'-methoxy[7-O-4',8-5']neolignan (1) and (7S,8R,7'S)-9,'0-dihydroxy-3,4-methylenedioxy-3',7'-dimethoxy [7-O-4',8-5'] neolignan (2), two new natural dihydrobenzofuran-type neolignans, along with 9,9'-dihydroxy-3,4-methylenedioxy-3'-methoxy [7-O-4',8-5'] neolignan (3) and (-)-machicendiol (4), were isolated from the whole plants of Breynia fruticosa. The structures of 1 and 2, including the absolute configurations, were determined by spectroscopic methods and circular dichroism (CD) techniques. The absolute configuration of 4 was confirmed by calculations of the OR spectrum, together with OR and ECD spectra of its p-bromobenzoate ester (4a). (C) 2013 Phytochemical Society of Europe.
