%X 采用乙酸乙酯萃取法从牛蒡子提取物中除去脂溶性成分, 再取水相干燥物用制备型HPLC分离, 共得到6个化合物, 并通过理化性质与光谱方法进行了结构确证, 分别为3, 4-二羟基苯丙烯酸-4-氧-β-D-葡萄糖苷、3-O-咖啡酰奎宁酸、3, 4-二羟基苯丙烯酸、3, 5-二咖啡酰奎宁酸、1, 5-二咖啡酰奎宁酸和3, 4-二咖啡酰奎宁酸.<br>The fat soluble components in the extractive of <i>Fructus arctii</i> were removed by ethyl acetate, the aqueous phase drying was isolated by preparative HPLC, and six compounds were isolated from the extractive of <i>F. arctii</i> and their structures were identified by physicochemical property analysis, specially by spectral analysis. Their structures were identified as 3, 4-dihydroxy cinnamic acid-4-O-β-D-glucoside, 3-O-caffeoylquinic acid, 3, 4-dihydroxy cinnamic acid, 3, 5-dicaffeoylquinic acid, 1, 5-dicaffeoylquinic acid and 3, 4-dicaffeoylquinic acid. Isolation of caffeoylquinic acid compounds from the extractive of <i>F. arctii</i> has not been reported in related literature, and the results of this study may provide support for the research of <i>F. arctii</i> and <i>F. arctii</i>-based preparations
