葡萄籽中原花青素的提取及应用现状

摘要

原花青素（ proanthocyanidins，PC）是目前国际上公认的清除人体内自由基最有效的天然抗氧化剂，广泛分布于多种天然植物中。阐述了葡萄废弃物中原花青素的功能，分析了其应用开发现状。结合常用的提取方法，并综合国内外关于原花青素的研究进展，对葡萄籽中原花青素提取的工艺参数进行优化，从而得出葡萄籽中原花青素最优提取方案。以期为葡萄籽的全面利用和原花青素的工业化生产提供科学依据，使原花青素拥有更广泛的应用。%Currently, proanthocyanidins is internationally recognized as the most effective natural antioxidants which can scavenge free radicals in the body.Proanthocyanidins is widely distributed in natural plants.This paper described the function of proanthocyanidins in the grape waste, and analyzed its application development status.Combined with common extraction method, and the progress of proanthocyanidins at home and abroad, the process parameters of extracting the anthocyanin from grape seed was optimized, and the best extraction method of proanthocyanidins from grape seeds was get.The paper was expected to provide scientific basis for industrialized production and comprehensive utilization of proanthocyanidins from grape seed, so as to the proanthocyanidins has a wider application.
