RESUMO: "Um desidro-rotenóide produzido por cultura de calos e por raízes de plantas silvestres de Boerhaavia coccinea". Cultura de calos foram estabelecidos de folhas e galhos fi nos de plântula de B. coccinea produzida in vitro e analisada para isofl avonóide. A quantifi cação do 6,9,11-triidroxi-6a,12a-desidro-rotenóide isolado das raízes de B. coccinea P Miller, coletada em seu habitat natural, e do mesmo rotenóide produzido na cultura de células estão descritos neste artigo. A análise rotineira em CLAE mostrou que a cultura de calos produziu o mesmo isofl avonóide encontrado nas raízes da planta do campo. A quantidade do metabólito secundário produzido in vitro foi de 955.35 g/g de massa seca de callus, atingindo uma concentração de 2,5 vezes maior do que a quantidade do metabólito produzido pela planta em seu meio ambiente natural.Unitermos: Boerhaavia coccinea, Nyctaginaceae, metabólitos secundários, cultura de células vegetais, isofl avonóide, desidro-rotenóide, rotenóide.
ABSTRACT:Calli cultures were established from leaves and stem of B. coccinea plantlet produced in vitro and analysed for isofl avonoid content. The quantifi cation of 6,9,11-trihydroxy6a,12a-dehydrorotenoid isolated from the roots of Boerhaavia coccinea P. Miller collected from its natural environment, and the same metabolite produced in callus tissue culture of the same plant are described in this paper. The rotinary quantitative HPLC analysis indicated that callus culture produced the same isofl avonoid compound found in the roots of intact wild growing plant. The amount of the secondary metabolite produced in vitro was 955.35 g/g of dry cell weight, 2.5 times more than the highest amount concentration produced by the wild growing plant in its natural environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
