摘  要:
目的:建立反相高效液相色谱法同时测定青梅非果部位(花、枝、叶)中新绿原酸(NCA)、绿原酸(CA)及隐绿原酸(CCA)3种绿原酸异构体的含量。方法:采用高效液相色谱法梯度洗脱,使用LunaC18色谱柱,以体积分数2%乙酸溶液和乙腈为流动相,二极管阵列检测器在波长328nm处进行检测。结果:该方法线性范围宽,3种绿原酸异构体的线性范围均为5~200μg/mL,NCA、CA、CCA的检出限分别为0.21、0.16、0.29μg/mL,定量限分别为0.76、0.50、0.98μg/mL,测得青梅花、枝、叶的30%乙醇提取物中3种绿原酸异构体的总含量分别为(48.26±0.11)、(10.82±0.04)、(21.33±0.08)μg/g。结论:该方法简便、快速、准确,青梅花、枝、叶是优良的绿原酸类化合物天然资源。

摘  要:
Three chlorogenic acid isomers,namely,neochlorogenic acid,chlorogenic acid,and cryptochlorogenic acid in the flowers,branches,and leaves of Prunus mume were simultaneously determine by a HPLC method.The samples were separated by a Luna C18 column using 2%acetic acid and acetonitrile as a mixed mobile phase.The detection wavelength was 328 nm.The analytical method displayed a wide linear range of 5 to 200μg/mL for the three chlorogenic acid isomers.The detection limits were 0.21,0.16μg/mL and 0.29μg/mL for neochlorogenic acid,chlorogenic acid,and cryptochlorogenic acid,respectively.The contents of total chlorogenic acid isomers were(48.26±0.11),(10.82±0.04)mg/g,and(21.33±0.08)mg/g in the flowers,branches and leaves of Prunus mume,respectively.In conclusion,this method is simple,rapid,accurate and sensitive,and Prunus mume is a good source of chlorogenic acids.
