Extraction of bioactive compounds from cob and pericarp of purple corn (Zea mays L.) by sequential extraction in fixed bed extractor using supercritical CO2, ethanol, and water as solvents

- Anthocyanins and phenolic compounds from cob and pericarp of purple corn were extracted in a sequential extraction with scCO2, ethanol and water.
- The ethanolic and aqueous extracts are rich in anthocyanins and phenolic compounds in general.
- The highest global yields and of compounds of interest were obtained in aqueous extraction.
- The majority anthocyanin was the cyanidin-3-glucoside with 71-77% of total.
