摘　　要：由于虾青素具有极高的应用价值,近几十年来,虾青素的应用研究取得了很大的进展。本文以Derwent Innovations Index(DII)数据库为统计分析源,检索并分析了数据库中关于虾青素的所有专利产出,利用Thomson Data Analyzer(TDA)分析工具和Thomson Inovation分析平台进行数据挖掘。通过对专利申请趋势、高产机构、核心技术、专利布局、热点技术领域等方面的计量分析,揭示了全球虾青素技术的发展现状,探索我国发展虾青素技术面临的机遇与挑战。虾青素的应用集中在鱼类饲料的添加剂和疾病治疗两个领域。日本、美国和中国为排名前三的优先权受理国,日本公司的申请数量占主导地位,从专利布局看,杜邦和东曹公司几乎全部集中在发酵或使用酶的方法合成目标化合物或组合物或从外消旋混合物中分离旋光异构体和微生物或酶其组合物这两个领域,而排名靠前的日本公司的研究领域主要集中在医用、牙科用或梳妆用的配制品、食品、食料或非酒精饮料制备或加工处理以及化合物或药物制剂的特定治疗活性三个领域。In recent decades,the applied research of astaxanthin has made significant progress since it is highly valued and promising in its application. Using the databases of Derwent Innovations Index（ DII） as the sources,we retrieved and analyzed the patents on the astaxanthin. The analytical tools of Thomson Data Analyzer（ TDA）,and Thomson Innovation platform were used for data mining. We analyzed the trends of patents applications,life spans,and distribution of patents,core patents and the patents family about astaxanthin by bibliometric approach. This paper reveals the trends of astaxanthin research in the world and helps the researchers and corporations in China to understand the opportunities and challenges to develop the new astaxanthin technology. The results showed that the research of astaxanthin mainly focused on the fields that astaxanthin was applied as a feed additives for fish and a natural nutrient for diseases prevention and control. Japan,the United States,and China ranked as the top three countries that claimed the priority of the patent applications of astaxanthin. The numbers of patent applications of astaxanthin from Japan prevailed over any other countries. From the distribution of the patents,DuP ont and Tosoh Corporation are mainly interested in the synthesis of the target compounds by fermentation and enzyme and the composition of microorganisms or enzymes,while other top Japanese companies mainly focused on products with the medical,dental or toilet use,the food preparation or processing of food and non-alcoholic beverages and the specific treatment of active compounds or pharmaceutical formulations.
