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.

Key words: Euphorbiaceae, Euphorbia yinshanica, ent-pimarane diterpenoid, 2D NMR
