Delavayol, a novel sesquiterpene from Incarvillea delavayi Bureau et Franchet.
To investigate the chemical constituents from Incarvillea delavayi Bureau et Franchet, a new sesquiterpene, named delavayol, together with three known ones, was isolated by column chromatography. Spectroscopic and chemical evidence revealed the structures to be 8beta,9beta-dihydroxy-1(10)-eremophiliene-11,12-diol (1), oleanolic acid (2), myrianthic acid (3), and sitoindoside I (4). Compounds 3 and 4 were isolated from the genus Incarvillea for the first time.
