摘要: 为充分开发丰富的柑桔果皮资源,增加其经济附加值,采用碱溶酸析法提取椪柑果皮中橙皮苷,经D-101大孔树脂纯化,再运用紫外-可见光谱扫描法分析了温度、时间、氧气、光照、pH值、金属离子等对橙皮苷的稳定性影响。结果表明:该方法提取、纯化的橙皮苷,经HPLC法检测,纯度达到96.7%,得率1.92%。提纯的橙皮苷水溶液在75℃以下加热30 min之内,以及无氧、无光、酸性及中性条件下可保持其性能稳定;Fe3+、Cu2+对橙皮苷氧化起诱导加速作用,且在充分的氧气和光照下,特别是强光下,会引起其结构变化。

Abstract: In ordor to use the peel of orange fully for maximum economic profits,the alkali-extraction and acid-precipitation method for extraction and the D-101 macroporous resin for purification of hesperidin from orange peels were used and the stability of hesperidin was investigated under conditions such as different temperature,time,oxygen, light,pH,metal ion,et al. The results showed that the content of hesperidin extracted by this method was 96.7%(HPLC), the extraction rate was 1.92%.Its solution was stable in the conditions as following: below 75℃, within 30 min,oxygenless, lightproof and acidic or neutral environment, whereas hesperidin would be oxidated to result in the molecular structure change if Fe3+,Cu2+ exisied,and in the condition with rich oxygen and light,especially strong light.

Key words: Citrus reticulate Blanco, hesperidin, stability
