红花芽菜中维生素C及几种微量元素的测定
摘要：维生素C 是人体维持生长保证健康所必需的,营养物质,许多保健食品中都含有.目前国内测定维生素C的方法有几种有2 ,4 —二硝基苯肼法、荧光光度法及液相色谱法.前两种方法试样前处理比较复杂,后一种方法由于各种样品基体不同,干扰因素不同及检测条件不完善,通常应用不多.但检测条件是分离效果的关键,我们通过摸索条件,建立了反相高效液相色谱法测定保健食品中维生素C ,平均回收率为94.101.3 % ,相对标准偏差为4.6.1 % ,最低检出浓度为0.001mg/ ml ,该方法灵敏、快速、准确.红花具有活血化瘀,凉血解毒,解郁安神等功效.本实验采用反相高效液相色谱法测定红花中维生素C和原子吸收分光光度法(AA S) 测定红花中部分金属元素的含量,通过以上实验对红花芽菜进行研究.

Red flower bud several dishes in the vitamin C and the determination of trace elements Abstract:vitamin C is human body keep growth necessary to ensure healthy,nutrients,many health foods contain.At present domestic determination of vitamin C,there are several ways of 4-2 2 nitrobenzene hydrazine method,fluorescence spectrophotometry and performance liquid chromatographic method.The former two sample pretreatment method is complex,a kind of method after due to various different,interference factors sample matrix is not perfect detection conditions and different,normally used much.But detection conditions is the key,we separation effect of groping conditions,established by reversed phase high performance liquid chromatography (HPLC) health food of itamin C,and the average recovery was 94.7 101.3 %,the relative standard deviation is 4.6 6.1 %,lowest detected concentration is 0.001mg/ml,this method was sensitive,rapid and accurate.Red flower with promoting blood circulation to remove blood stasis,cool blood XieYu effect such as detoxifying,and nerves.This experiment using reversed-phase high-performance liquid chromatography (HPLC) in vitamin C and red atomic absorption spectrophotometry (AA S) was in the red part metal elements of content,by the above experiments.Red bud dishes Keywords:safflower vitamin C reversed phase high performance liquid chromatography metal element determination {重复了说｝
