Ecdysteroids and a sucrose phenylpropanoid ester from Froelichia floridana

Phytoecdysteroid glycosides 1-5 and a phenylpropanoid ester of sucrose 6 were isolated from Froelichia floridana, along with eight known compounds (7-14). Compounds 1-2 and 6-14 were tested in vitro for their activity against DNA topoisomerase I, but only diosmetin (13) exhibited marginal inhibition.
