抄録

Sixteen new acylated iridoid glycosides, called buddlejosides A_1-A_<16>, were isolated from Buddleja japonica HEMSL., together with four known iridoid glycosides; 6-vanilloyl-ajugol, 6-feruloyl-ajugol, verbascoside A, and 6-O-[α-L-(4-O-feruloyl)-rhamnopyranosyl]-catalpol. Structures of the new compounds were determined on the basis of chemical and spectroscopic evidence. Buddlejosides A_1 was an ajugol derivative acylated with monoterpenic acid, A_2 was an sinuatol and A_3-A_<16> were 6-rhamnopyranosyl-catalpol derivatives acylated with cinnamic acid derivative and acetic acid.
