Resumo: | The infusion used as a beverage and known as tea of Paraguay or male (Ilex paraguarensis, St. Hil.) contains vitamin B (aneurin). 2) Aneurin determinations were made on the infusion commonly used (water extract) and on the complete water and alcohol extracts. The presence of aneurin was detected in both extracts. For quantitative study aneurin was adsorbed from the extracts (pH 3.8-4.0) by means of fuller's earth and kaolin. 3) Animal tests with pigeons and mice (curative, preventive and maintenance of body weight) give positive but inconstant results. No exact quantitative values could be obtained with the animal test. 4) Schopfer-Jung test based on the development of the mould « Phycomyces blakesleeanus, Bgf » showed constant results. Regular growth curves were obtained with the adsorbate of kaolin and fuller's earth. 5) The thiochrome fluorescence test introduced by Jansen was applied to the detection of aneurin in the adsorbate and good results were found which check closely with those encountered by the Schopfer-Jung test. 6) The determinations of aneurin by means of the Phycomyces and thiochrome tests gave values varying from 60 to 280 y per 100 gr. 7) Green leaves are more rich in aneurin than dry ones. |
