Embodiment 1
[0045] Example 1. Black-bone fowl melanin extract in SHSY-5Y cell injury model induced by 6-OH DA Protective effects
[0046] 1. Experimental materials
[0047] 1. Black-bone fowl melanin extract: Take the silky fowl melanin extract prepared according to the above-mentioned method for extracting black-bone fowl melanin, and suspend it in normal saline at a concentration of 0.2g / ml.
[0048] 2), 10mM 6-OH DA storage solution: accurately weigh 5mg of 6-OH DA·HBr (purchased from SIGMA), dissolve it in 2ml of distilled water containing 0.01% vitamin C, filter with 0.22μm microporous membrane Sterilize and store in aliquots at -20°C. Dilute it to the appropriate concentration before use.

Embodiment 3
[0092] Example 3 Protective action of silky fowl melanin extract in MPTP-induced Parkinson's disease mouse model use
[0093] 1. Experimental materials
[0094] 1) Silky fowl melanin extract: Take the silky fowl melanin extract prepared according to the above-mentioned silky fowl melanin extraction method, and suspend it in normal saline at a concentration of 0.2g / ml for use.
[0095] 2). Healthy C57BL / 6 male mice: weighing 22g to 27g, provided by Beijing Weitonglihua Animal Breeding Center. Each cage is raised in groups of 4 to 5, the bottom of the cage is covered with sawdust, 12 hours / 12 hours day and night cycle lighting, free drinking and eating. Adapt to the environment for 4 to 5 days before the start of the experiment.
