Zou Y, Yin DM, Gang J, Du XW, Liu CH, Gu ZX. Study on germplasm characteristics of ChiShui black-bone chickens and the value of health care of its melanin. Comparison of physicochemical properties and antioxidant activities of melanin from fruit-bodies and fermentation broths of Auricularia auricula. Study on protein extraction from Auricularia auriculata by alkali dissolution and acid precipitation. elegans compared with the worms in the vehicle group ( P < 0.05). elegans ( P < 0.05), and enhance locomotion behavior of C. auricula-judae melanin could significantly prolong the lifespan of C.

For example, at a concentration of 1 mg/mL, the scavenging rate of these free radicals was 85.71% ± 0.02%, 91.34% ± 0.01%, and 91.81% ± 0.01%, respectively. auricula-judae melanin to superoxide anion-, ABTS +., and OH Enzyme extraction under the following conditions yielded melanin of 2.21% ± 0.03%: 150 min, enzyme-to-substrate ratio of 1.1%, pH 4.4, 50☌, and 52 min. auricula-judae melanin had strong absorption at a wavelength of 192 nm, with a absorbance-concentration equation of y = 0.7042x + 0.2114. The in vitro free radical scavenging ability of melanin and its antioxidant effects on C. Further, extraction conditions were optimized using the Box-Behnken design. The biological enzymatic method was performed to break the cell wall and prepare melanin extract. This study investigated the extraction method of Auricularia auricula-judae melanin, focusing on the tough cell wall of the fruiting body and its free radical scavenging ability and antioxidant effects on Caenorhabditis elegans.
