Three New Diterpenoids from <i>Euphorbia wallichii</i>

Abstract

Abstract Three new abietane diterpene lactones, 3α‐hydroxyjolkinolide A (1), ent‐8α , 14β‐dihydroxy‐ 13(15)‐ene‐16(1 2α)‐ abietanolide (2) and ent‐8α, 14α‐dihydroxy‐13(15)‐ene‐16(12α)‐abietanolide (3) as well as a known abietane diterpene jolkinolide A (4) were isolated from the roots of Euphorbia wallichii . Their structures were elucidated on the basis of spectroscopic analysis.
