Ultrasound-Assisted Extraction and RSM Optimisation of Phenolic Compounds from Helichrysum arenarium with Chlorogenic Acid Quantification
Helichrysum arenarium L. Moench is a phenolic-rich plant, yet optimised extraction and characterisation of its bioactive compounds remain limited. This study developed an ultrasound-assisted extraction method combined with response surface methodology and central composite design to optimise the recovery of total phe...
