Pour chicken comb powder into an enamel pot, adde distilled water 6 – 7 times, stir uniformly, soaking for more than 24 hours, fully swelling that chicken comb powder, filtering, collecting filtrate, soaking the filter residue for 3 times according to the same method, and combining the filter solutions for 3 times. Pouring the filtrate into a ceramic cylinder, adding 10 % of solid sodium chloride under stirring, adding chloroform with equal volume, stirring for 3h, and separating out water phase. Adding 95 % ethanol with 2 times volume into the separated aqueous phase, stirring, standing overnight, precipitating hyaluronic acid, filtering to dry the precipitate, and drying to obtain crude product. The crude product was redissolved in 4 volumes
0 1 mol / l sodium chloride solution, adjust the ph with dilute hydrochloric acid =
4.5 – 5, adding chloroform with equal volume, standing for layering, and sucking out the upper water phase. The aqueous phase was adjusted to ph = with 8 % sodium hydroxide solution …
