| Abstract
| - Two new acylated flavonoids have been isolated from the resinous exudates of Pseudognaphaliumrobustum and Pseudognaphalium cheirantifolium. Their structures were elucidated by high-resolutionspectroscopic methods as 5,7,8-trihydroxy-3-methoxyflavone 8-O-[(E)-2-methyl-2-butenoate] (1) and 5,7,8-trihydroxy-3,6-dimethoxyflavone 8-O-[(E)-2-methyl-2-butenoate] (2).
