Genicunolide A, B and C: three new triterpenoids from Euphorbia geniculata
Three new triterpenoids, designated as genicunolide A (1), B (2) and C (3), along with friedelin (4) and friedelinol (5), were isolated from the aerial parts of Euphorbia geniculata. They were characterized as 1β-acetoxy-3β-hydroxy-11α,12α-oxidotaraxer-14-ene, 1β,3β-diacetoxy-21α-hydroxy-11α,12α-oxi...
