Abstract:
:An uncommon, previously unreported p-quinone-lignan compound called justicidone (4-(1,3-benzodioxol-5-yl)-6-methoxynaphtho[2,3-c]furan-1,5,8(3H)-trione) (2), along with the known savinin (1) were isolated from Justicia hyssopifolia (Acanthaceae). Their structures were determined by spectroscopic methods.
