AB  - Opuntia genus includes several species able to grow in arid regions and known for producing delicate fruits, which are far from being thoroughly characterized. Herein, fruits from O. macrorhiza and O. microdasys were divided in skins and pulps (without including seeds) and studied for chemical composition, individual phytochemicals and bioactivity. The major volatiles were camphor and ethyl acetate, while citric acid was the main organic acid. The fatty acids detected in highest percentages were linoleic acid (skins) and lauric acid (pulps); α-tocopherol was the major isoform of vitamin E. Quercetin-3-O-rutinoside and quercetin-O-(deoxyhexoside-rutinoside) were the main phenolics in fruit skins of O. macrorhiza and O. microdasys (respectively), similarly to piscidic acid in O. macrorhiza pulp (O. microdasys pulp showed no quantifiable compounds). Betanin and isobetanin were the major betalains. All samples were antioxidant (particularly O. macrorhiza), but antimicrobial activity was only detected in skins. Cytotoxicity was low in all cases. Overall, these fruits proved to be potential new ingredients for food or pharmaceutical related applications, adding value to these natural species able to grow in arid environments.

AB  - Opuntia spp. flowers have been traditionally used for medical purposes,
   mostly because of their diversity in bioactive molecules with health
   promoting properties. The proximate, mineral and volatile compound
   profiles, together with the cytotoxic and antimicrobial properties were
   characterized in O. microdasys flowers at different maturity stages,
   revealing several statistically significant differences. O. microdasys
   stood out mainly for its high contents of dietary fiber, potassium and
   camphor, and its high activities against HCT15 cells, Staphylococcus
   aureus, Aspergillus versicolor and Penicillium funiculosum. The
   vegetative stage showed the highest cytotoxic and antifungal activities,
   whilst the full flowering stage was particularly active against
   bacterial species. The complete dataset has been classified by principal
   component analysis, achieving clearly identifiable groups for each
   flowering stage, elucidating also the most distinctive features, and
   comprehensively profiling each of the assayed stages. The results might
   be useful to define the best flowering stage considering practical
   application purposes.
