發(fā)布時間:2019-04-09 12:57
【摘要】:目的建立右歸飲的HPLC指紋圖譜,并同時測定9種成分(京尼平苷酸、莫諾苷、綠原酸、梔子苷、馬錢苷、松脂醇二葡萄糖苷、甘草苷、蘆丁和甘草酸)的量,為控制右歸飲的質(zhì)量提供依據(jù)。方法采用Pursuit XRs 5 C18色譜柱(250mm×4.6 mm,5μm)進行分離,流動相為乙腈-0.1%磷酸水溶液,梯度洗脫,體積流量1.0 m L/min,檢測波長230 nm,柱溫30℃。建立10批右歸飲樣品的HPLC指紋圖譜,并進行相似度評價;通過與各組方藥味及對照品的保留時間和紫外光譜圖比對,對共有峰進行歸屬和指認(rèn),并測定指認(rèn)出的9個成分的量。結(jié)果 10批樣品指紋圖譜與對照指紋圖譜的相似度均大于0.904;共標(biāo)定30個共有峰,其中8個來自杜仲,8個來自甘草,6個來自山茱萸,2個來自附子,2個來自熟地黃,1個來自肉桂,山藥及枸杞對共有峰貢獻不明顯,其中3個共有峰不能明確其來源;通過對共有峰進行指認(rèn),發(fā)現(xiàn)7號峰為京尼平苷酸、9號峰為莫諾苷、11號峰為綠原酸、12號峰為梔子苷、13號峰為馬錢苷、14號峰為松脂醇二葡萄糖苷、18號峰為甘草苷、21號峰為蘆丁及30號峰為甘草酸,并對這9種成分進行了定量測定,其定量測定結(jié)果分別為87.6~119.1μg/g、323.6~365.6μg/g、108.3~124.1μg/g、79.5~85.0μg/g、171.7~188.0μg/g、163.0~238.3μg/g、64.5~53.3μg/g、159.8~168.5μg/g、72.8~83.6μg/g。結(jié)論所建立的右歸飲HPLC指紋圖譜及定量測定方法穩(wěn)定性、重復(fù)性好,可為右歸飲質(zhì)量控制和評價提供參考。

It provides the basis for controlling the quality of Youguiyin. Methods Pursuit XRs-5 C18 column (250mm 脳 4.6 mm, 5 渭 m) was used. The mobile phase consisted of acetonitrile-0.1% phosphoric acid aqueous solution, gradient elution, volume flow rate 1.0ml / min, detection wavelength 230nm, column temperature 30 鈩,
