The document summarizes research conducted on phytochemical extracts from red beetroot, purple Opuntia fruits, and yellow Opuntia fruits. It describes obtaining extracts rich in betalains and polyphenols from the plant materials and evaluating the extracts' bioactivity. Specifically, the beetroot extract was purified using solid phase extraction and fractions were characterized. The purified beetroot fraction was then tested in yeast models of neurodegenerative diseases and for anti-inflammatory activity, finding potential neuroprotective effects.
