摘要：
The insect anti-juvenile hormones precocene I and II (7-methoxy-2,2-dimethyl-2H-1-benzopyran and 6,7-dimethoxy-2,2-dimethyl-2H-1-benzopyran) were identified in three of nine Nama (Hydrophyllaceae) species. Precocene I occurred in N. lobbii while precocene II occurred in N. hispidum, N. lobbii and N. sandwicense. N. hispidum contained the highest concentration (ca 0.5% dry weight) of precocene II, which was found in the leaves, stems, seed capsules, corolla, glandular trichomes, and seeds. In addition to the anti-juvenile hormone, insect juvenile hormone activity was detected in the organosoluble extracts of N. rothrockii and N. sandwicense. N. sandwicense is the first plant discovered to contain compounds with both anti- and juvenile hormone activity.
