title: A new (propylphenyl)bibenzyl from Eria bambusifolia.
abstract: A new (propylphenyl)bibenzyl, bambusifolol (1), along with six known compounds, batatasin III (2), tristin (3), 3-hydroxy-5-methoxy bibenzyl (4), gigantol (5), 3',5-dimethoxy-9,9'-diacetyl-4,7'-epoxy-3,8'-bilign-7-ene-4'-methol (6) and balanophonin (7) were isolated from the whole plants of Eria bambusifolia. Their structures were elucidated by the means of extensive spectroscopic analysis. 3-7 were isolated from the genus Eria for the first time and 2 obtained originally from E. bambusifolia. All the compounds isolated were evaluated for their cytotoxicity against human tumour HL-60, SMMC-7721, A-549, MCF-7 and SW-480 cell lines, but none showed significant activity.
