## 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__)β20,28βepoxyβ3βhydroxyursβ21βenβ28βone (**1**), (3__Ξ²__,18__Ξ²__)βursβ21βeneβ3,20,28βtriol (**2**), and (3__Ξ²__,18__Ξ±
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
