Ten amide compounds were isolated from Physochlaina infundibularis Kuang, of which N-[4-(acetylamino)butyl]- 3-(3,4-dihydroxyphenyl)-2-propenamide (1) was a new natural product and its structure was elucidated by comprehensive spectra data. Compounds 2–10 were isolated from Physochlaina genus for the first time. [ABSTRACT FROM AUTHOR]
