Clinacanthus nutans Lindau: Effects of drying methods on the bioactive compounds, color characteristics, and water activity

The application of solar drying (SD) and heat pump-assisted solar drying (HPSD) on the retention of flavonoid components, total color changes, and water activity of Clinacanthus nutans Lindau leaves were investigated. Analysis of data shows significantly higher extractable yield and flavonoid (orien...
