Abstract:Objective To propose as method for determination of curcumin, demethoxycurcumin and bisdemethoxycurcumin in Shenlian granules by HPLC method. Methods The Agilent-C18 (4.6 mm×250 mm, 5 μm) chromatography column was performed for separation with methanol(A)–3% HAc(B) as the mobile phase (35∶65, V/V). The flow rate was 1.0 mL·min-1, detection wavelength was set at 412 nm, column temperature was maintained at 30℃ and the injection volume was 10 μL. Results The curcumin, demethoxycurcumin, and bisdemethoxycurcumin had good linearity with the range of 39.17 ~1530.0 ng(r=0.999 9), 48.90~1910.0 ng(r=1.000 0) and 44.65~1744.0 ng(r=1.000 0), respectively. The average recoveries were 97.86%(RSD=1.01%), 95.46%(RSD=1.07%) and 99.69%(RSD=0.46%), respectively. Conclusion The established method was verified by methodology which has a good advantage of simple operation, analysis rapidly and high accuracy which can be used for the determination of curcumin, demethoxycurcumin, and bisdemethoxycurcumin in Shenlian granules by HPLC.

參莲颗粒是由苦参、山豆根、防己、三棱、莪术、丹参、补骨脂、苦杏仁、乌梅和白扁豆等七位药组成,具有活血化瘀、清热解毒和软坚散结的作用,临床主要用于气血瘀滞、热毒内阻而导致的中晚期肺癌和胃癌病患者[1]。方中三棱具有消积止痛、破血行气的作用[2],莪术具有行气破血、消积止痛的功效[3],二者合用共同为方中君药,有报道[4-5]称莪术的主要成分为姜黄素类和挥发油,姜黄素类是其主要活性成分,主要有姜黄素、去甲氧基姜黄素、双去甲氧基姜黄素[6-7],这三种化合物结构相似,均具有抗动脉粥样硬化、抗癌、抗氧化、抗诱变和清除自由基的作用[8-10],且有报道称去甲氧基姜黄素可以抑制TPA (12—O—tetradecanoyl phorbol—13-acetate)引起的癌细胞增生以及多种癌细胞[11],作用大于其它两种姜黄素类,由于参莲颗粒主要是治疗癌症等症状,根据刘昌孝院士提出的中药质量标志物(Q-Marker)[12]的概念,把能够作为与中药功能主治和反映药品安全性和有效性的活性成分作为中药质量标志物从而对其进行质量控制。……
