SOTERO, Víctor, MACO, Martha, VELA, Jorge et al. Evaluación de la actividad antioxidante y compuestos fenólicos en pulpa y semillas de cuatro frutales amazónicos de la familia Sterculiaceae. Rev. Soc. Quím. Perú, ene./mar. 2011, vol.77, no.1, p.66-74. ISSN 1810-634X.

Species of the Sterculiaceae family in study went: cacao (Theobroma cacao L.), cacahuillo (Herrenia nitida). copoazú (Theobroma grandiflorum (Willd. Ex Spreng Schum) and macambo (Theobroma bicolor Humb & Bompl). The major concentration of polyphenols was presented in the seeds of cocoa with 12101,46 mg/100g, and copoasu with 9691,94 mg/100g, and pulp of macambo with 5738,81 mg/100g. Higher concentration of flavonoids were presented at the seeds of cocoa and cacahuillo with 2037,16 and 1542,91 mg/100g, respectively, consecutively is the pulp of macambo with 711,68 mg|/100g and in anthocyanins it is obtained that seed of the cocoa presented the major concentration with 638,02 mg/100g, very distant to the pulps of copoazú and macambo with 81,62 and 51,84 mg/100g, respectively. On those which were determined certain composites of flavonides by chromatography of HPLC. Higher presence is observed of rutin trihydrate so much in seeds as in the pulp of these fruits in values that go of 7022,0 to 10689,0 mg/100g for seed of macambo and cocoa respectively. High concentrations of quercetina in seed of copoazú with 18173,0 mg/100g and in seed of cacahuillo with 17280,0 mg/100g and the best concentration of epicatequina, was encountered in the seed of cacahuillo with 578,2 mg/100g.
