Abstract(s)
Hot air drying has proven to be an efficient method to preserve specific edible plant materials
with medicinal properties. This is a process involving chemical, physical, and biological
changes in plant matrices. Understanding these processes will lead to an improvement in the yields
of bioactive compounds. This study aims to optimize the drying process of two species’ fruits used
in folk medicine, Berberis vulgaris and Crataegus monogyna. The optimized extracts’ antioxidant capacity
was assessed using various assays, with the barberry extract showing very good activity
(50.85, 30.98, and 302.45 mg TE/g dw for DPPH, TEAC, and FRAP assays, respectively). Both species
exerted good fungal α-glucosidase inhibitory activity (IC50 = 0.34 and 0.56 mg/mL, respectively) but
no activity on mammalian α-glucosidase. Additionally, this study identified and quantified the
main bioactive compounds. The results presented herein are a breakthrough in industrializing this
drying process. Additional studies are necessary to mechanistically understand the drying process
involved in these plant materials.
