Abstract

From the whole plant of Dracocephalum forrestii (Labiatae), three new and nine known triterpenoids were isolated. The new compounds were identified as (3__Ξ²__,18__Ξ²__)‐20,28‐epoxy‐3‐hydroxyurs‐21‐en‐28‐one (1), (3__Ξ²__,18__Ξ²__)‐urs‐21‐ene‐3,20,28‐triol (2), and (3__Ξ²__,18__Ξ±__,19__Ξ±__)‐ursane‐3,20,28‐triol (3) by means of in‐depth spectroscopic analysis.

and lycopodiin A (3), together with four known compounds, lycoclavanol (4), lycoclaninol (5), a-onocerin (6), and 3-epilycoclavanol (7), were isolated from Lycopodium japonicum Thunb (Lycopodiaceae). Their structures were established by means of spectroscopic analyses. Compounds 3 and 7 showed moder
