摘要

背景:肉豆蔻是具有重要药理作用的重要香料。目的:采用反相高效液相色谱法对肉豆蔻提取物进行标准化分析。设置与设计:建立了同时定量测定肉豆蔻和肉豆蔻提取物中槲皮素(QUE)、丁香酚(EUG)、肉豆蔻素(MYRS)和黄樟酚(SAFR)含量的反相高效液相色谱法。材料与方法:采用Waters 2695 Alliance体系,2996光电二极管阵列检测器(PDA)进行反相高效液相色谱(RP-HPLC)检测。QUE, EUG, MYRS和SAFR在反相250 × 4.6 mm, 5-m, Zorbax SB C18色谱柱(Agilent)上分离。流动相为0.1%正磷酸,水溶液pH为2.5(溶剂a),乙腈(溶剂b)。选择梯度程序进行分离。PDA设置在220 nm处,所有峰均显示最大响应。统计分析:采用标准公式计算相对标准偏差百分比(% RSD)和相关系数(r2)。结果:QUE、EUG、MYRS、SAFR均获得满意的溶解,滞留时间分别为3、7、19、21 min。对方法进行了验证,得到的相关系数和% RSD均符合可接受的值。结论:该方法准确、专属性好,可用于肉豆蔻提取物的分析。

Simultaneous assessment and validation of reverse phase-high performance liquid chromatography method for quercetin, eugenol, myristicin, and safrole from nutmeg, fruit and mace
Background: Nutmeg is the imperative spices having pharmacological importance. Objectives: The objective of this work was to standardize Nutmeg extract by RP-high performance liquid chromatography (HPLC) analysis. Settings and Design: An RP-HPLC method was developed for simultaneous quantification of quercetin (QUE), eugenol (EUG), myristicin (MYRS), and safrole (SAFR) from nutmeg fruit and mace extracts. Materials and Methods: RP-HPLC method was performed with Waters 2695 Alliance system using a 2996 photodiode array detector (PDA). QUE, EUG, MYRS, and SAFR were separated on a reverse-phase 250 × 4.6 mm, 5-m, Zorbax SB C18 column (Agilent). The mobile phase was prepared from 0.1% orthophosphoric acid in water of pH 2.5 (solvent-A) and acetonitrile (solvent-B). The gradient program was selected for separation. The PDA was set at 220 nm, which shows maximum response for all peaks. Statistical Analysis: Percent relative standard deviation (% RSD) and correlation coefficient (r 2 ) were calculated by standard formulas. Results: QUE, EUG, MYRS, and SAFR were satisfactorily resolved with retention time about 3, 7, 19 and 21 min. respectively. The method was validated and results obtained showed accepted values for correlation of coefficient and % RSD. Conclusions: The method was accurate and specific for analysis of nutmeg extract.
