Abstract
The frond exudate of the fern Notholaena nivea var. nivea contains a n ovel dihydrostilbene as a major constituent. This compound was identif ied by spectroscopic methods as 3-hydroxy-5,4-dimethoxy-6-carboxylic b ibenzyl, which is isomeric to the earlier reported notholaenic acid. T he exudate of N. nivea also contains flavonoid aglycones which form pa tterns that are characteristic for the two varieties. The distribution of notholaenic and isonotholaenic acids in further Notholaena species is reviewed.
