TITLE: | |
摘要: | 目的:建立同时测定杉寄生药材中2种黄酮类成分落新妇苷和芦丁含量的反相高效液相色谱(RP-HPLC)法,并比较不同产地药材中2种成分的含量。方法:色谱柱为SHISEIDO-SPOLAR C18,流动相为乙腈-0.1%磷酸溶液(14 ∶ 86,V/V),流速为1.0 mL/min,检测波长为291 nm,柱温为35 ℃,进样量为10 μL;对来源于广西和广东6个市/县的杉寄生药材进行含量测定及比较分析。结果:落新妇苷和芦丁的检测质量浓度线性范围分别为22~440、12~240 μg/mL(r分别为0.999 6、0.999 1),平均加样回收率分别为99.44%、99.96%(RSD分别为1.38%、1.50%,n=9);杉寄生中落新妇苷含量在各省/区及各市/县之间均相似(0.862 5~0.901 1 mg/g),芦丁含量在同一省/区的市/县间相似,但在2个省/区之间差异较大(平均值分别为0.431 3 、0.214 9 mg/g)。结论:本法简便、准确、稳定、重现性好,可用于杉寄生药材的质量控制。 |
ABSTRACT: | OBJECTIVE: To establish RP-HPLC method for simultaneous determination of astilbin and rutin in Macrosolen cochinchinensis, and to compare the contents of 2 components in medicinal material from different producing areas. METHODS: The determination was performed on SHISEIDO-SPOLAR C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid (14 ∶ 86, V/V) at the flow rate of 1.0 mL/min. The detection wavelength was set at 291 nm, and column temperature was 35 ℃, the sampling volume is 10 μL.Content determination and comparative analysis of M. cochinchinensis from 6 counties of Guangxi and Guangdong were conducted. RESULTS: The linear range of astilbin and rutin were 22-440 μg/mL (r=0.999 6) and 12-240 μg/mL (r=0.999 1); average recoveries were 99.44% (RSD=1.38%, n=9) and 99.96% (RSD=1.50%, n=9). The contents of astilbin in M. cochinchinensis were similar between provinces/autonomous region or among cities/counties (0.862 5- 0.901 1 mg/g); the contents of rutin were similar among cities/counties in same provinces/autonomous region but there was a great difference between provinces/autonomous region (average values were 0.431 3, 0.214 9 mg/g). CONCLUSIONS: This method is simple, accurate, stable and reproducible for the quality control of M. cochinchinensis. |
