摘要: 运用特征性颜色反应、高效液相色谱(HPLC)和质谱(MS)等技术对浅红色毛叶杜鹃(R. championae Hook)花瓣花色素提取液进行初步鉴定和含量测定。结果表明:该杜鹃品种的花色素含有非红色的黄酮类化合物,主要有黄酮、黄酮醇、二氢黄酮等色素,其中还有部分酚类色素。高效液相色谱(HPLC)显示杜鹃花色素提取液至少包括39种物质,其中有7种可以确定,分别为杨梅黄素3-半乳糖苷、槲皮素3-半乳糖苷、槲皮素-鼠李糖苷、槲皮素3-葡萄糖苷、锦葵素3-阿拉伯糖苷-5葡萄糖苷、杨梅黄素3-鼠李糖苷、绿原酸。利用紫外分光光度法测得杜鹃花瓣中花色苷的含量为131.025mg/100g,总黄酮含量为10.68mg/g。

Abstract: Anthocyanin pigments from Rhododendron championae Hook flowers (light red color) were primarily identified and quantified by the specific color reactions and HPLC-MS/MS. Anthocyanins were extracted by grinding with liquid nitrogen. The resulting extract was found to contain non-red flavonoid compounds (mainly flavonoids, flavonols and flavanones) and some phenolic compounds. HPLC analysis demonstrated that the extract contained at least 39 compounds, of which, 7 were identified to be myricetin-3-galactoside, quercetin3-galactoside, quercetin-3-rhamnoside, quercetin-3-glucoside, malva-3-arabinoside-5-glucoside, myricetin-3-rhamnoside and chlorogenic acid, respectively. Rhododendron championae Hook flowers were determined by UV spectrophotometry to contain 131.025 mg/100 g anthocyanin and 10.68 mg/g total flavonoids.
