摘要：
From aerial parts of Centaurea aspera var. subinermis a new homoderivative of the grasshopper ketone has been isolated. Its structure was determined as 5-acetyloxy-3,9a-dihydroxy-9a-homomegastigma-6,7-dien-9-one mainly from the NMR spectra. From C. salmantica a new phaseic acid derivative has been isolated, and the structure determined as 5,12-epoxy-9-hydroxy-7-megastigmen-3-one. In addition, several known norisoprenoids and a new carboxylic acid glucoside have been isolated.
