Abstract:
:Three new ursane-type triterpenoids, 2α,3β-dihydroxy-11α,12α-epoxy-urs-28,13β-olide (1), 2α,3β,24-trihydroxy-11α,12α-epoxy-urs-28,13β-olide (2), and 2α,3α,24-trihydroxy-11,20(30)-dien-urs-28,13β-olide (6), together with six known ursane-type triterpenoids (3-5, 7-9), were isolated from the EtOAc extract of the aerial parts of Isodon excisoides. Their structures were elucidated on the basis of 1D NMR and 2D NMR analyses as well as HRMS experiments.
