Genicunolide A, B and C: three new triterpenoids from Euphorbia geniculata.


ABSTRACT: 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 1?-acetoxy-3?-hydroxy-11?,12?-oxidotaraxer-14-ene, 1?,3?-diacetoxy-21?-hydroxy-11?,12?-oxidotaraxer-14-ene and 3?,9?,20?-trihydroxy-?-taraxast-5-ene, respectively, by spectral and chemical methods.

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-oxidotaraxer-14-ene and 3β,9α,20α-trihydroxy-Ψ-taraxast-5-ene, respectively, by spectral and chemical methods. ...[more]
