中文摘要：
黑米是一种营养丰富的稻种资源,它的特殊颜色使其具有抗氧化、预防心脑血管疾病等多种功能。因此针对黑米色素的组成成分、鉴定方法、稳定性、提取分离和纯化方法的研究也取得了一定的研究进展。研究证明,黑米色素成分主要为花色素,其中含量最高的是矢车菊素-3-葡萄糖苷;黑米色素的检测方法以液相色谱法和分光光度法应用性最好;稳定性的研究证明黑米色素在酸性、低温和避光的条件下有助于黑米色素的保存;针对黑米色素的提取和纯化方法应用较多的分别是溶剂提取法和大孔树脂纯化法。黑米色素成分和提取工艺的研究进展将会促进黑米色素的利用和黑米的精深加工。
英文摘要：
Black rice is a nutritious rice.Its special color also gives its unique properties such as antioxidant activity,cardiovascular and cerebrovascular prevention.Therefore,its components identification,stability,extraction and purification were studied.It was proved that the main components of black rice pigment were anthocyanins,and cyanidin-3-glucoside content was the highest.Liquid chromatography and spectrophotometric were better for the detection of the pigment.Acidic,low temperature,and dark condition help to the preserve the black rice pigment.Solvent extraction and macroporous resin purification method were used as the main extraction and purification methods.The research progresses of black rice pigment composition and extraction technology will promote the further research on the processing and utilization of black rice and its pigment.
