What this means
Researchers extracted sugar compounds from a fungus using microwaves and peroxide, then tested them on tiny worms. The worms lived longer under oxidative stress, but this was not tested in people.

Abstract
Oxidative stress, as the core pathological mechanism of imbalance in the body's oxidation-antioxidation system, is a key inducer of accelerated aging and degenerative diseases. This study, based on the synergistic principle of microwave energy and free radicals, constructed a microwave-assisted hydrogen peroxide (H2O2) synergistic system to optimize the extraction yield of Auricularia auricula-judae polysaccharide (AAPs-m) using the Box-Behnken design model based on single-factor experiments. A methyl viologen-induced oxidative stress model of Caenorhabditis elegans was established to evaluate the in vivo antioxidant stress capacity of AAPs-m. The results showed that the AAPs-m yield reached 36.76% ± 0.38% under the conditions of a liquid-to-solid ratio of 60.0 mL/g, a H2O2 concentration of 1.5% a microwave power of 400 W, and a temperature of 100°C for 61 min. AAPs-m is a heteropolysaccharide composed of mannose, glucuronic acid, glucose, galactose, and xylose, with a molar ratio of 53.82:6.10:25.50:2.36:11.44. Among them, the molar ratio of mannose is high, which is rare in AAPs extracted by other methods. AAPs-m significantly prolonged the lifespan of C. elegans under oxidative stress conditions (P P 2O2 synergistic technology, possesses antioxidant stress capabilities and has great potential and development value.
