摘　　要：从玄参科三色马先蒿(Pedicularis tricolor)全草的乙醇提取物中分离得到17个化合物,采用波谱方法鉴定了它们的结构。其中化合物1(2,3,5-tirmethoxy-4-hydroxy-xanthone)是一个新的酮,命名为三色马先蒿酮A(pedicutricone A);2(8α-hydroxyl-4-carboxyl-5βH,9βH-iridoid-1α-glycoside)是一个新的环烯醚萜苷,命名为三色马先蒿苷A(pedicutricoside A);化合物3～17为首次从该植物中分离得到。To search for new bioactive constituents from Pedicularis tricolor, a new xanthone named pedicutricone A （1） and a new iridoid named pedicutricoside A （2）, ＇along with fifteen known compounds, were isolated from the ethanol extracts of the whole plants of P. tricolor for the first time. Their structures were elucidated based on spectroscopie methods, including two-dlmensional nuclear magnetic resonance analysis.
