Two novel sesquiterpenoids from Ainsliaea fragrans Champ.
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.
