Eriodictyon sessilifolium, an endemic Hydrophyllaceae of Baja California (Mexico), has been studied for the natural products exuded by glandular trichomes covering its leaves and stems. Major components of this exudate were isolated and identified by spectroscopic methods to be 4-hydroxy-3-(2,3-dihydroxy-3-methylbutyl)-benzoic acid methyl ester (1), the natural methyl ester of anodendroic acid (2), and 2,2-dimethyl-3-hydroxychroman-6-carboxylic acid methyl ester (3). Possible biosynthetic relations between these new natural products are considered. In addition, 9 known flavonoid aglycones were identified as exudate constituents.

The aerial parts of Scorzonera aristata Ramond ex DC., collected in the South Tyrolean Dolomites, yielded the flavonoids quercetin 3- O-glucoside, rutin, and isoorientin, and the caffeic acid derivatives chlorogenic acid, 4,5-dicaffeoyl quinic acid, and 3,5-dicaffeoyl quinic acid. Sub-aerial parts contained caffeic acid methyl ester, 3,5-dicaffeoyl quinic acid, and the triterpenes 3α-hydroxyolean-5-ene, lupeol, and magnificol. Chemosystematic implications of the isolated compounds are discussed briefly.
