A new sesquiterpene lactone, 3beta-O-beta-D-glucopyranosyl-8alpha-hydroxy-11alpha,13-dihydrozaluzanin C (1), and a novel trinorguaiane-type sesquiterpene, 4beta,10alpha-dimethyl-1beta,5alpha-bicycle[3,5,0]dec-6-en-4alpha,10beta-diol (2), together with three known compounds, glucozaluzanin C (3), 11alpha,13-dihydrozaluzanin C (4), and 8alpha-hydroxy-11alpha,13-dihydrozaluzanin C (5), were isolated from the whole plant of Ainsliaea fragrans Champ. The structures of 1 and 2 were elucidated on the basis of detailed spectral analysis. Structures of the known compounds were identified by comparison of its spectral data with those values in the literature.
从杏香兔儿风全草中分离得到一个新的倍半萜内酯，3β - O - β - D - 吡喃葡萄糖基 - 8α - 羟基 - 11α,13 - 二氢扎鲁扎宁C（1），一个新的三降愈创木烷型倍半萜，4β,10α - 二甲基 - 1β,5α - 双环[3,5,0]癸 - 6 - 烯 - 4α,10β - 二醇（2），以及三个已知化合物，葡糖扎鲁扎宁C（3）、11α,13 - 二氢扎鲁扎宁C（4）和8α - 羟基 - 11α,13 - 二氢扎鲁扎宁C（5）。通过详细的光谱分析阐明了化合物1和2的结构。通过将已知化合物的光谱数据与文献中的值进行比较来鉴定其结构。
