A New Glycoside and a Novel‐Type Diterpene from Hemerocallis fulva (L.) L.

Abstract

AbstractThe CHCl3 extract of dried roots of Hemerocallis fulva (L.) L. afforded a novel diterpene named hemerocallal A (1), which is the second reported naturally occurring diterpene with a trans‐bicyclo[5.1.0]octane system. The BuOH extract afforded a new glycoside named hemerocalloside (2). Their structures were established on the basis of spectroscopic and chemical studies.
