[EN] In the regions of Canary Islands, it is prevailing all the year a high level of solar radiation. This force plants to develop defence mechanisms against excessive production of free radicals through the accumulation of antioxidant substances. Plants contain a diverse group of phenolic compounds with the structural requirements of free radical scavengers. The effects of different extracting solvents have been tested for the extraction of phenolic compounds from plant material. On the present study we compare the total phenolic contents (TPC) and antioxidant activities of several extracts derived from Aloe vera plants. The phenolic compounds present in the extracts were identified and quantified by RP­HPLC techniques.
