继续报道从紫红獐牙菜Sivertia punicea Hemsl,全草中分得的另八个化合物(Ⅰ～Ⅷ)的结构,经光谱解析,I的结构推定为6′-O-β-D-吡喃葡萄糖基獐牙菜甙(6′-O-β-D-glucopyranosylsweroside,Ⅰ),为一新的裂环环烯醚萜甙类化合物,命名为紫药苦甙(swertiapunimarin),Ⅱ～Ⅷ的结构分别鉴定为獐牙菜甙(sweroside,Ⅱ)、獐牙菜苦甙(swertiamarin,Ⅲ)、齐墩果酸(oleanolic acid,Ⅳ)、胡萝卜甙(daucosterol.Ⅴ)、β-谷甾醇(B-sitosterol,Ⅵ)、2,3-二羟基-1,4-苯二甲酸(2,3-dihydroxy-1,4-benzodicarboxylic acid,Ⅶ)及methylswertianin.以上均首次从该植物中得到。
Continue to report the structure of the other eight compounds (I to VIII) obtained from Swertia purpurea Sitrtia punicea Hemsl, whole plant. After spectral analysis, the structure of I was assumed to be 6′-O-β-D-glucopyranose. Basidiomycetes (6′-O-β-D-glucopyranosylsweroside, I) is a new split-ring iridoid compound, named Swertiapunimarin, and the structures of II-VIII are respectively It was identified as swerside (II), swertiamarin (III), oleanolic acid (IV), carrot (daucosterol. V), β-sitosterol (B-sitosterol). , VI), 2,3-dihydroxy-1,4-benzodicarboxylic acid (VII) and methylswertianin. were obtained from the plant for the first time.
