摘要: 建立了一种简单、快速、环保的免柱基质固相分散萃取(FMSPD)方法用于喜树果中喜树碱的萃取。基于七元瓜环(Q[7])对喜树碱的识别作用,将Q[7]作为FMSPD的固相分散剂,选择性地从喜树果中萃取出喜树碱,并将其转移到水相,采用高效液相色谱-紫外检测器(HPLC-UV)直接测定其含量。对各种影响萃取效率的因素,包括Q[7]的用量、研磨时间、加入水的量以及溶液的pH值进行了考察。在优化的实验条件下,建立的FMSPD-HPLC-UV分析方法的线性范围为1.0~100 μg/mL,检出限(S/N=3)为0.15 μg/mL,日内和日间精密度分别为4.5%和5.2%。4个浓度水平的加标回收率在97.1%~119.3%范围内。对3个不同产地喜树果中喜树碱的含量进行了测定,F检验法和t检验法表明,本方法与传统超声提取法之间无显著性差异,本方法具有更简单、快速和不使用有机溶剂的优点。

Abstract: A simple, rapid and environmentally friendly method named column-free matrix solid-phase dispersion (FMSPD) was developed for extraction of camptothecin from the fruits of Camptotheca acuminate Decne. Cucurbit[7]uril (Q[7]) was used as the sorbent of FMSPD to selectively extract camptothecin, which was transferred into an aqueous solution and was directly detected using high performance liquid chromatography-ultraviolet detector (HPLC-UV) based on the recognition interaction of Q[7] toward the compound. The factors that influenced the extraction efficiency were investigated, including the amount of Q[7], grinding time, volume of added water, and pH value of the solution. Under the optimal experimental conditions, the dynamic linear range of the developed FMSPD-HPLC-UC method was 1.0-100 μg/mL, the limit of detection was 0.15 μg/mL, and the intra- and inter-day precisions were 4.5% and 5.2%, respectively. The mean recoveries (n=3) at three spiked concentration levels were from 97.1% to 119.3%. The developed method was applied to analyze four kinds of fruits of Camptotheca acuminate Decne.F- and t-tests showed that the results had no significant difference when comparing the traditional ultrasound-assisted extraction method to the novel FMSPD extraction method. However the method developed here was simpler, faster and did not use organic solvents.
