Abstract

?Um desidro-roten?ide produzido por cultura de calos e por ra?zes de plantas silvestres de Boerhaavia coccinea?. Cultura de calos foram estabelecidos de folhas e galhos finos de pl?ntula de B. coccinea produzida in vitro e analisada para isofl avon?ide. A quantifica??o do 6,9,11-triidroxi-6a,12a-desidro-roten?ide isolado das ra?zes de B. coccinea P Miller, coletada em seu habitat natural, e do mesmo roten?ide produzido na cultura de c?lulas est?o descritos neste artigo. A an?lise rotineira em CLAE mostrou que a cultura de calos produziu o mesmo isoflavon?ide encontrado nas ra?zes da planta do campo. A quantidade do metab?lito secund?rio produzido in vitro foi de 955.35 ?g/g de massa seca de callus, atingindo uma concentra??o de 2,5 vezes maior do que a quantidade do metab?lito produzido pela planta em seu meio ambiente natural. ; ABSTRACT: Calli cultures were established from leaves and stem of B. coccinea plantlet produced in vitro and analysed for isofl avonoid content. The quantification of 6,9,11-trihydroxy- 6a,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 isoflavonoid 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.
