The present application intends relates to method for obtaining extracts of condensed tannins from aerial part of Cistus ladanifer. The invention contemplates the extraction of condensed tannins, present in aerial part of Cistus ladanifer, where, before the extractive process, the biomass is dried and ground to a particle size less than 1 mm (1). After this preparation, the biomass undergoes the extraction procedure, with an ultrasonic probe (2, 4) and using a mixture of acetone:water as extraction solvent. The extraction process is controlled in relation to time, temperature and solid:liquid ratio. This process for obtaining extracts of condensed tannins from Cistus ladanifer have potential for application in the feedstuffs industry. |
