title: Iridoids from Pedicularis kansuensis forma albiflora.
abstract: A new iridoid glycoside kansuenoside (1) and a new iridoid kansuenin (2), along with eight known compounds (3-10) were isolated from the whole plant of Pedicularis kansuensis forma albiflora Li. Their structures were elucidated by spectroscopic methods. Nine of them were assayed against Bacillus subtilis, Escherichia coli, and Staphylococcus aureus.
