Tropane alkaloids and calystegines as chemotaxonomic markers in the Solanaceae.

This study assessed the occurrence and distribution of tropane alkaloids and calystegines in genera of the family Solanaceae to identify patterns of distribution and make evolutionary inferences. A database of tropane alkaloids and calystegines occurrences was constructed from the results of a search of scientific websites and a hand search of periodicals. The terms "Solanaceae", "tropane alkal...

Flavonoids as chemotaxonomic markers for Erythroxylum australe.

Methanolic leaf extracts of Erythroxylum australe F. Muell. produced eight O-conjugated flavonoids. Six of the flavonoid aglycones were dihydroisoflavones (all dihydro-orobol derivatives), one a flavanone, eriodictyol, and one a flavonol, quercetin. The major glycosides of the flavonoids included mono-glucosyl-rhamnosyls and dirhamnosyl-glucosides with either 3, 5, 7 or 3', 4' linkage or a comb...

Plant Long-chain Polyprenols as Chemotaxonomic Markers.

The occurrence of long-chain polyprenols in leaves of plants of Lauraceae, Tiliaceae and Magnoliaceae families was studied. Separation of groups of polyprenols differing in the size of molecules was performed by thin-layer chromatography. In all studied species long-chain polyprenols were detected. The total polyprenol content in leaves reached values as high as 3% of their dry weight. In the s...
