Abstract
Las cáscaras de maní son un residuo generado en grandes cantidades en Bolivia. Este residuo contiene luteolina, que es un flavonoide con demostradas propiedades farmacológicas como antioxidante, antiinflamatorio y antimutagénico. En este estudio, se analizó el contenido de luteolina en 41 muestras de cáscaras de maní obtenidos en diferentes cultivares principalmente del departamento de Chuquisaca, Bolivia. El contenido de luteolina se cuantificó por un método de HPLC-DAD utilizando como patrón interno quercetina. Los resultados mostraron que el contenido varía entre 0,006 y 0,850 mg Lu/g de cáscaras. Las muestras con mayor concentración de luteolina fueron: Larguillo Icla (tostado) (0,850 mg Lu/g de cáscaras) obtenida en el mercado de la ciudad de Sucre, Phiti cintura colorado de Oroncota en Potosí con 0,673 mg Lu/g de cáscaras y Pico y Loro obtenido de Monteagudo en Chuquisaca con 0,589 mg Lu/g de cáscaras. Por otra parte, los extractos de EtOH que también presentan propiedades farmacológicas interesantes, fueron también analizados en su contenido de luteolina, determinando concentraciones de hasta 79,728 y 74,188 mg Lu/g de extracto en los cultivares de Phiti cintura colorado de Oroncota en Potosí y Phiti cintura ladrillo de Padilla en Chuquisaca, respectivamente. Finalmente se determinó que la temperatura de tostado (80°C) no afecta a la luteolina.
Peanut shells are a residue generated in big quantities in Bolivia. This residue contents luteolin, which is a flavonoid with demonstrated pharmacological properties as antioxidant, anti-inflammatory and antimutagenic. In this study, we analyzed the luteolin content in 41 samples of peanuts shells obtained from different cultivars mainly in the department of Chuquisaca, Bolivia. The luteolin content was quantified by an HPLC-DAD method using quercetin as internal standard. Results showed that content varies between 0.006 to 0.850 mg Lu/g of shells. Samples with the highest concentration of luteolin were: Larguillo Icla (roasted) (0,850 mg Lu/g of shells) sample obtained in the market of Sucre city, Phiti cintura colorado from Oroncota in Potosi with 0.673 mg Lu/g of shells and Pico y Loro obtained from Monteagudo in Chuquisaca with 0.589 mg Lu/g of shells. On the other hand, the EtOH extracts, which also showed interesting pharmacological properties, were also analyzed in their luteolin contents, determining concentrations of 79,728 and 74,188 mg Lu/g of extract in the cultivars Phiti cintura colorado from Oroncota in Potosí and Phiti cintura ladrillo from Padilla in Chuquisaca, respectively. Finally, it was determined that roasting temperature (80 ° C) does not affect luteolin.
