Effects of fermentation treatment on antioxidant and antimicrobial activities of four common Chinese herbal medicinal residues by Aspergillus oryzae

The feasibility of using Aspergillus oryzae NCH 42, an extracellular tannase-producing fungus, for increasing the utilization of extraction residues of Chinese herbal medicines (CHMs) was evaluated in this study. Four types of CHMs, including Trichosanthes kirilowii Maxim, Salvia miltiorrhiza Bge, Magnolia officinalis and Glycyrrhizae radix, were used. Their aqueous extraction residues were inoculated with A. oryzae NCH 42, and solid-state...
