Thermoprotective properties of Opuntia ficus-indica f. inermis cladodes and mesocarps on sheep lymphocytes

摘要

This study aims to investigate the thermoprotective properties of Optmtia ficus-indica f. inermis. Extracts were prepared from cladodes (CE) and mesocarps (ME), then subjected to a spectrophotometric and LC-MS analyses. Lymphocytes were isolated from peripheral blood of non-stressed sheep, supplemented with CE, ME, betanin or alpha-tocopherol, and subjected to two thermal treatments: 40 and 41 degrees C, for 6h. Viable lymphocytes and H2O2 production were evaluated.
