【摘要】：建立同時測定新疆紫草Arnebia euchroma不同部位中左旋紫草素、β-羥基異戊酰紫草素、乙酰紫草素、β-乙酰氧基異戊酰阿卡寧、去氧紫草素、異丁酰紫草素、β,β'-二甲基丙烯酰阿卡寧和異戊酰紫草素等8種羥基萘醌含量的高效液相色譜法。采用Waters Xbridge C_(18)色譜柱(4.6 mm×250 mm,5μm),流動相乙腈-0.05%甲酸水溶液(70∶30),檢測波長275 nm,流速1mL·min~(-1),柱溫30℃。定量結果顯示,新疆紫草各部位中主要成分含量差異較大,根皮含量最高,其次是根,再次是莖殘基,根木質部和地上部分含量較低。本研究為確定紫草藥用部位提供科學依據。
[Abstract]:A new method for simultaneous determination of levovalerate, 尾-hydroxyisovalerate shikonin, acetyl shikonin, 尾-acetoxy isovalerate acanine, oxyshikonin, isobutyryl shikonin, 尾-butyryl shikonin in different parts of Arnebia euchroma in Xinjiang was established. High performance liquid chromatography (HPLC) of 8 kinds of hydroxynaphthoquinone such as 尾'- dimethylpropene acanine and isovalerate shikonin. A Waters Xbridge C18 column (4.6 mm 脳 250 mm, 5 渭 m) was used. The mobile phase consisted of acetonitrile-0.05% formic acid aqueous solution (70:30). The detection wavelength was 275nm, and the flow rate was 1mL 路min ~ (- 1). The column temperature was 30 鈩，
