|
Abstract:
中文摘要:美洲大蠊 Periplaneta americana是重要的药用昆虫,具有抗菌消炎、活血化瘀等多种药用价值。本实验通过外标法鉴定了美洲大蠊乙醇提取物中的原儿茶酸,并建立原儿茶酸定量测定的超高效液相色谱方法。色谱柱选用Waters ACQUITY UPLC HSS T3柱(2.1 mm×100 mm,1.8 μm),缓冲盐溶液(含0.1%甲酸,25 mmol甲酸铵)为流动相A,100%乙腈为流动相B,流速0.5 mL·min -1,样品温度25℃,柱温40℃。结果显示,美洲大蠊乙醇提取物中原儿茶酸可达到基线分离,峰型良好;原儿茶酸在10~160 μg内呈良好的线性关系( R 2=0.999 9),平均回收率为98.30%~99.57%,相对标准偏差<1%;定量测定美洲大蠊乙醇提取物中原儿茶酸的含量为51.38 μg·mL -1。结果显示,超高效液相色谱方法重复性好、稳定性高、分析快速,可以用于美洲大蠊乙醇提取物中原儿茶酸含量的定量测定。
英文摘要:The present study reported an ultra performance liquid chromatography (UPLC) based method to quantity determine the protocatechuic acid in the ethanol extract of Periplaneta americana. The column was washed with Waters ACQUITY UPLC HSS T3 column (2.1 mm×100 mm, 1.8 μm). The salt solution (containing 0.1% formic acid, 25 mmol ammonium formate) was used as the mobile phase A, and 100% acetonitrile at a flow rate of 0.5 mL·min -1 was used as the mobile phase B. The specimen temperature was 25℃, and column temperature was 40℃. Three detection wavelengths were set at 190-450 nm, 254 nm and 360 nm, respectively. The protocatechuic acid peak at a retention time of 3.3 min with a base line separation was detected. The protocatechuic acid showed a linear relationship ( R 2=0.999 9) in the linear range, and the average recovery ranged from 98.30% to 99.57% with the relative standard deviation<1%. The content of protocatechuic acid in the ethanol extract from P. americana was quantity determined to be 51.38 μg·mL -1. The establishment of UPLC method to determine the content of protocatechuic acid will facilitate the quality control of P. americana basic productions in future. 2018,37(2): 185-190 收稿日期:2017-07-07 DOI:10.11984/j.issn.1000-7083.20170216 分类号:R286 作者简介:郭昕(1992-),女,硕士研究生,研究方向:农业昆虫与害虫防治,E-mail:1534657074@qq.com *通讯作者:李静,E-mail:ljtjf@126.com 参考文献: 陈启亮, 唐东昕, 龙奉玺. 2015. 土家药蜚蠊的研究进展[J]. 时珍国医国药, 26(7):1719-1721. 冯光维, 刘志东, 祁东利, 等. 2016.
