title: [Studies on the chemical constituents from roots of Agastache rugosa].
abstract: Eleven compounds were isolated from roots of Agastache rugosa and eight of them were identified as maslinic acid (I), oleanolic acid (II), 3-O-acetyl oleanolic aldehyde (III), acacetin (IV), tilianin (V), agastachoside (VI), daucosterol (VII) and beta-sitosterol (VIII). Compound IX is a new diterpenoid and its structure was proposed to be 19(4----3)abeo-11,14-dihydroxy-12-methoxy-abieta-8,11,13,15- tetraen-7-one based on spectral data, named dehydroagastol. The studies on X and XI are in progress.
