郑毅男，男，1945年出生，汉族，中共党员，民盟盟员，吉林省第九届人大代表，留日医学博士，吉林农业大学中药材学院教授，作物栽培学与耕作学学科博士生导师。吉林省特产学会副理事长，中国人参学会常务理事，中国植物学会药用植物及中药专业委员会委员，国家中医药管理局“中药学”重点学科学科带头人。

先后为硕士、博士研究生主讲《中药炮制学》、《天然药物化学》等多门课程；在科学研究上，一直从事中药方面研究，尤其在人参加工理论方面颇有见地，发现红参加工是遵循梅拉德反应的原理；同时发现人参中具有广泛生理活性的AFG，是首次自人参中分离得到的新天然化合物，其含量超过人参总皂苷，为人参的评价和临床应用提供了新的理论依据。曾先后主持国家、部省级科研项目15项，获得多项科研成果，其中获省科学技术进步二等奖1项；获长春市科技进步二等奖1项，其中“人参非皂苷抗衰老保健品开发研究”经鉴定达到国际领先，已经申请“人参次级皂苷脂肪酸酯合成及其应用”、“人参果提取物的制备方法及治疗糖尿病的药物用途”等发明专利2项；多年来，发表学术论文100余篇，其中SCI收录9篇；出版科技著作2部。主要从事保健食品和癌症辅助治疗药物的研究，现正主持教育部、科技厅以及横向联合等3项在研基金项目。
