摘　　要：从阴山大戟的根部首次分到一个已知的对映-海松烷型二萜,3α,19-dihydroxyl-ent-pimara-9,15-diene,通过二维波谱方法(1 H-1 H COSY,HMBC,HMQC,ROESY)确定了其结构,并且首次此化合物的H谱和C谱数据进行了全归属.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.
