Abstract

|
Three mold strains, Aspergillus oryzae (A. oryzae), Aspergillus kawachii (A. kawachii), and Monascus purpureus (M. purpureus), were tested for fermentation of Acanthopanax senticosus (A. senticosus) leaf, root, stem, and fruit powders. The fermented A. senticosus materials were then tested for bioactive materials (phenolic compounds, flavonoids, mineral and fatty acid) and biological activities (DPPH free radical scavenging activity, reducing power, and tyrosinase inhibition activity). The highest concentrations of phenolic compounds and flavonoids were NFASL at 4.11% and MPASL at 2.30%, respectively. Major minerals were Ca, K, Mg and Mn. Major fatty acids in fermented A. senticosus powders were palmitic, linolenic, and stearic acids. DPPH radical scavenging activity was slightly stronger in non-fermented than in fermented A. senticosus. Tyrosinase inhibition activity was stronger in fermented A. senticosus than in NFAG. The Fe/Cu reducing powers were stronger in non-fermented A. senticosus than in any of the fermented A. senticosus materials. Overall, the study provides basic data for understanding the biological activities and chemical characteristics of A. senticosus fermented by molds for the development of functional foods.
