目的研究紫花地丁全草的化学成分。方法采用多种色谱技术分离化合物，通过理化性质和光谱数据鉴定化合物的结构。结果分离鉴定了7个化合物，分别为七叶壳（1）、异东莨菪内酯（2）、6-羟甲基-3-吡啶醇（3）、5，5-双（6，7-二羟基香豆素）（4）、6，6，7，7-四羟基-5，8-双香豆素（5）、乳乳香醇（6）、脱氢乳乳香醇（7）。结论化合物2-7均为首次从紫花地丁中分离得到。
OBJECTIVE To study the chemical constituents of the whole plant of Viola yedoensis. METHOD The compounds were isolated by various chromatographic techniques and their structures were elucidated by their physicochemical properties and the analysis of their spectral data. RESULT Seven compounds were isolated and identified as esculetin (1), isoscopoletin (2), 6-hydroxymethyl-3-pyridinol (3),5,5-bi (6,7-dihydroxycoumarin) (4), 6,6,7,7-tetrahydroxy-5,8-bicoumarin (5), loliolide (6), dehydrololiolide (7). CONCLUSION Compounds 2-7 were isolated from V. yedoensis for the first time.
