title: [Medicinal plants--concentrators of chromium. The role of chromium in alkaloid metabolism].
abstract: Mass screening of medicinal plants of the flora of Russia (196 species) was performed for chromium content. A total of 124 species-chromium concentrators were found, in which the chromium content markedly exceeded the mean values, this excess being 4- to 6-fold in 54 species, 7- to 3-fold in 62 species, and 37- to 114-fold in seven species. The greatest capacity of chromium accumulation was shown for the sand immortelle, foxglove, Alexandrian laurel, Greek valerian, marsh cudweed, adenostilis, and lobelia. These species are considered as potential sources of chromium for correction of its deficiency in humans. Some mechanisms underlying the effect of chromium on metabolism of alkaloids derivative of quinolizidine, tropane, isoquinoline, and indole, were deciphered.
