This study to investigate anti-influenza components from the bark of Alnus japonica resulted in the isolation of two rare acylated diarylheptanoids, named oregonoyl A (5) and oregonoyl B (6), along with nine known compounds (1-4 and 7-11). Their structures were elucidated on the basis of extensive spectroscopic and chemical methods. Antiviral testing of compounds 1-11 against KBNP-0028 (H9N2) avian influenza virus showed that platyphyllone (10) was strongly active, and platyphyllonol-5-xylopyranoside (9) was moderately active against KBNP-0028 as compared with the positive control, zanamivir, respectively.

Four diarylheptanoid monoglycosides (2a), (2b), (3), and (4), in addition to the hydroxy ketone (1), were isolated from the female flowers of Alnus serrulatoides.On the basis of the physicochemical and the X-ray crystallographic analyses, these were chara
