原花青素广泛分布于高等植物的多种器官和组织中,是黄烷-3-醇的游离、寡聚或多聚物,存在侧基修饰、异构性质、聚合方式、聚合度等的多样性,可采用多种色谱和质谱技术进行纯化和鉴定。原花青素对于植物具有抗紫外线、清除自由基、抗病驱虫、影响种子休眠等功能,影响作物品质等性状,对人体也具有多种生理功效,在药物、化妆品、食品等领域有良好的应用前景。
Proanthocyanidins are widely distributed in various organs and tissues of higher plants.They are mono-,oligo-or polymers of flavan-3-ols,with diversified side chain modifications,stereoisomers,polymerization modes and polymerization degrees.They can be purified and identified using many methods based on chromatography and mass spectrometry.In plants,they play anti-UV,radical scavenging and pest resistant roles,and influence seed dormancy and crop quality traits.They also impose many beneficial physiological effects on human health,and have prosperous applications in drugs,cosmetics,foods,etc.
