我国海藻寡糖领域发展态势分析

海藻寡糖是来源广泛的海洋多糖的降解产物,具有抗氧化、抑菌、促进植物生长、诱导植物抗逆性等多种生物活性,开发前景广阔。以国家知识产权中国专利数据库为数据源,检索了1985-2015年期间我国海藻寡糖领域相关专利,从申请量、申请人、国际专利分类号、技术热点对海藻寡糖领域的发展态势进行分析。结果表明,从2010年开始,该领域相关专利申请量进入快速增长期;中国海洋大学在该领域技术优势明显,紧随其后的是中国海洋局第三海洋研究所、中国科学院海洋研究所;专利的技术热点主要在海藻寡糖的制备与应用两个方面,以制备为基础,对海藻寡糖在医药领域、食品与饲料添加剂、农业领域等方面的应用进行分支细化的研究。该研究结果对我国在海藻寡糖领域的发展和布局具有一定的借鉴意义。

Development Situation Analysis of Seaweed Oligosaccharides in China

Seaweed oligosaccharides degraded from the seaweed polysaccharide have multiple biological activities, including antioxidant, bacteriostasis, promoting plant growth, inducing plant stress resistance, thus having a wide development prospect. This paper analyzed seaweed oligosaccharides patents from application of numbers trends, patent assignee, IPC and technology hotspots, by qualitative analysis based on the database of State Intellectual Property Office from 1985-2015. The results showed that the related patent numbers had grown rapidly since 2010. Ocean University of China had obvious advantage in thid field of seaweed oligosaccharides, followed by Third Institute of Oceanography, State Oceanic Administration and Institute of Oceanology, Chinese Academy of Sciences. The research hotspots on patents were mainly focused on the preparation and application in medicine, preservation, feed additive and agricultural field based on the preparation of seaweed oligosaccharides. These research findings are of certain reference significance for the development and distribution of seaweed oligosaccharides in our country.
