2D NMR Assignments of an ent-Pimarane Diterpenoid from Euphorbia yinshanica
|
Abstract:
One known ent pimarane type diterpenoid, 3α, 19-dihydroxyl ent pimara- 9(11), 15-diene, has been isolated from the roots of Euphorbia yinshanica for the first time. Its structure has been confirmed by 2D spectral methods (1H-1H COSY, HMBC, HMQC, ROESY), and its NMR signals have been first completely assigned.
