医学免费论文:胡芦巴盐炙前后指纹图谱对比研究
【摘要】 目的 建立盐炙胡芦巴的指纹图谱测定方法,并对4个产地10批胡芦巴的生品和盐炙品进行对比实验,为胡芦巴饮片的质量控制提供可靠的方法。方法 采用HPLC法,色谱条件为:DiamonsilC18(250 mm×4.6 mm,5 μm)柱;流动相:乙腈水梯度洗脱;检测波长:211 nm;流速:1.0 ml/min;柱温:35 ℃;进样量:20 μl。结果 在相应的色谱条件下,胡芦巴生品和盐炙品的指纹图谱比较:盐炙品较生品少5个共有峰。结论 胡芦巴盐炙前后化学成分的种类或含量变化较大。

Comparison of fingerprints of semen trigonellae before and after stirheated with salt solutionLI Jinlian,HU Changjiang(Chengdu University of Traditional Chinese Medicine,Chengdu 610075,China)【Abstract】 Objective To establish a HPLC method for determination of fingerprints of semen trigonellae stirheated with salt solution,and to provide a reliable method for the quality control of this crude drug. Methods The separation was performed at a Rp C18(250 mm×4.6 mm,5 μm)column using acetonitrile and water as the mobile phase. The detection wavelength was 211 nm. The mobile phase consisted of acetonitilewater at the flow rate of 1.0 ml/min. The temperature of column was 35 ℃. The injection volume was 20 μl. Results At the same condition,fingerprints of semen trigonellae stirheated with salt solution was 5 common peaks less than those without salt solution. Conclusion The type or content of semen trigonellae appears to change greatly before and after stirheated salt solution.【Key words】 semen trigonellae; stirheated with salt solution; fingerprints医.学.全.在.线www.lindalemus.com
胡芦巴为豆科一年生草本植物胡芦巴Trigonella foenumgraecum L.的干燥成熟种子[1]。主要分布于地中海东岸、中东、伊朗高原及喜玛拉雅地区。在我国南北各地均有栽培,在西南、西北呈半野生状态,主产于河南商丘、甘肃天水、四川广元、金堂及安徽亳州,分布于东北、西南及河北、陕西、甘肃、新疆、山东、江苏、安徽、浙江、河南、湖北、广西等地。《中国药典》2005年版一部收载了生品和盐炙品:生品具有温助肾阳,祛寒,止痛的功效,用于肾阳不足,寒邪凝滞下焦的小肠疝气疼痛、腹胁胀满、腰痛、脚气疼痛及下元虚冷的阳痿、遗精、尿频等病证;盐胡芦巴可引药入肾,温补肾阳力专,常用于疝气疼痛,肾虚腰痛,阳痿遗精等症[24]。本研究主要对胡芦巴盐炙前后指纹图谱进行对比实验,以期为下一步的质量标准研究打下基础。
