Study on Chemical Constituents, Antioxidant and Wound Healing Promoting Activities of Pilose Antler Waste

In order to give better play to the reuse value of pilose antler waste, the chemical components and pharmacological activities of the waste were studied. Pilose antler medicinal materials were treated according to the production process of pilose antler oral liquid standard (Ministry of Health Standard: WS3-B-2232-96). Then the waste produced in the production of pilose antler oral liquid was reextracted by water extraction and alcohol precipitation. Ultrahigh performance liquid chromatography quadrupole electrostatic field orbital trap high resolution mass spectrometry (UPLC-Q-Orbitrap HRMS), bicinchoninic acid (BCA) and phenol-sulfuric acid methods were used to study the chemical components of the extract. The antioxidant capacity of the extract was evaluated by three ways including free radical scavenging test of 1,1-diphenyl-2-trinitrophenylhydrazine (DPPH), 2,2-diazo-bis (3-ethyl-benzothiazole-6-sulfonic acid) diammonium salt (ABTS) and Ferric ion reducing antioxidant power (FRAP). Moreover, the antioxid
