摘要
以杭白菊中总糖、黄酮类物质、绿原酸、木犀草苷4种有效成分含量为指标,比较江苏引种杭白菊与原产地浙江桐乡杭白菊的品质差异。采用苯酚硫酸法测定总糖含量,以紫外可见分光光度法测定黄酮类物质的含量,并通过高效液相色谱法测定绿原酸和木犀草苷的含量。结果表明,桐乡杭白菊引种江苏后,4种有效成分的含量均有所增高;与江苏本地杭白菊相比,除总糖含量外,黄酮类物质、绿原酸、木犀草苷的含量较高。由此可知,杭白菊引种江苏有益于杭白菊品质的提高。
Taking the total sugar,flavonoid,chlorogenic acid,luteolin-7-O-glucoside in Chrysanthemum morifolium Ramat as index to compare the quality of species from original habitats Zhejiang Tongxiang. Total sugar content in Chrysanthemum morifolium Ramat is measured by phehol-vitril. The content of flavonoids is analyzed by UV-Vis spectrophotometry. Chlorogenic acid and luteolin-7-O-glucoside is measured by high performance liquid chromatography(HPLC). The results indicate that the content of four effective components increased after Chrysanthemum morifolium Ramat in Tongxiang introduced to Jiangsu. The content of flavonoids,chlorogenic acid and luteolin-7-O-glucoside are higher in Chrysanthemum morifolium Ramat introduced Jiangsu than Jiangsu native,but the content of total sugar is lower. Therefore,The introduction of Chrysanthemum morifolium Ramat is beneficial to the quality improvement.
