摘要：
The methanolic extract of the twigs of Hoslundia opposita afforded two new pyrone-substituted flavonoids oppositin and 5-0-methylhoslundin, in addition to the known flavonoids tectochrysin, hoslunddiol and hoslundin. Oppositin has its 6-C-pyrone substituent attached via a 6,6''-link in contrast to the 6,5''-link in hoslundin and is a likely biogenetic precursor of hoslundin.
