ABSTRACT
The polymeric material in the latex of Himatanthus sucuuba (Spruce) Woodson was identified by spectroscopic methods as cis-polyisoprene (Mn = 192; Mw = 571; Mw/ Mn = 2.97). ICP-MS analysis of microelements in the aqueous phase showed the most abundant to be Ca (354 g/g) and Mg (250 g/g). Carbohydrate analysis of the aqueous phase by HPLC-PAD showed arabinose, glucose, xylose, rhamnose and galactose to be the predominant saccharides.
RESUMO
O polímero do látex de Himatanthus sucuuba (Spruce) Woodson foi identificado por métodos espectroscópicos como o cis-poliisopreno (Mn = 192; Mw = 571; Mw /Mn= 2.97). A análise de microelementos na fase aquosa por ICP-MS forneceu Ca (354 mg/g) e Mg (259 mg/g) como elementos majoritários. A detecção de carboidratos na fase aquosa por CLAE-DPA apresentou arabinose, glucose, xilose, ramnose e galactose como açúcares principais.
