Abstract: front page image
(EN)The measurement of gossypol in cotton seed products using conventional methods namely spectrophotometric, NMR methods, chemiluminsecent method, gas-liquid chromatography polarography, thin layer chromatography and paper chromatography are tedious, time-consuming, high cost and needs calibrated systems. In the present invention, a low cost and portable system is devised and the concentration of total gossypol is directly displayed on LCD in mgl-1 or ppm from the test solution and no standard solution is required to make calibration curve for measuring the absorbance.
(FR)La mesure du gossypol dans les produits à base de graines de coton à l'aide de méthodes traditionnelles, à savoir les méthodes spectrophotométriques et à résonance magnétique nucléaire, les méthodes par chimiluminescence, la polarographie par chromatographie gaz-liquide, la chromatographie sur couche mince et la chromatographie sur papier, est pénible, lente et onéreuse et elle exige des systèmes étalonnés. La présente invention propose un système portatif et peu coûteux permettant d'afficher directement sur un écran à cristaux liquides la concentration de gossypol total en mgl-1 ou en ppm dans la solution testée, et aucune solution témoin n'est nécessaire à l'établissement d'une courbe d'étalonnage pour la mesure de l'absorbance.
