Two sew beta-dihydroagarofuran sesquiterpene polyol esters named celas
trine A (1) and celastrine B (2), as well as three known sesquiterpene
s (3-5), were isolated from the seed ail of Celastrus flagellaris. The
ir structures were elucidated as 1 alpha,6 beta,8 alpha,13-tetraacetox
y-9 alpha-(benzoyloxy)-beta-dihydroagarofuran (1) and 1 alpha-acetoxy-
2 alpha,9 beta-bis(cinnamoyloxy)-beta-dihydroagarofuran (2) on the bas
is of spectroscopic evidence.
