摘要:目的 建立HPLC同时测定红花药材中羟基红花黄色素A、芦丁、槲皮素、山柰素4种化学成分含量的方法。方法 采用Agilent ZORBAX SB-C18色谱柱(4.6 mm×250 mm,5 ?m),DAD检测器,以0.5%磷酸溶液(A)-甲醇(B)进行梯度洗脱,柱温为30 ℃,流速为0.8 mL/min,进样量为10 ?L,检测波长为360 nm。结果 羟基红花黄色素A在0.077 6~0.776 0 ?g(r=0.999 9)、芦丁在0.046 0~0.460 0 ?g(r=0.999 6)、槲皮素在0.006 4~0.064 0 ?g(r=0.999 9)、山柰素在0.012 8~0.128 0 ?g(r=0.999 7)范围内呈良好线性关系。羟基红花黄色素A、芦丁、槲皮素、山柰素的平均回收率分别为99.68%、99.78%、102.03%、97.03%,RSD(n=6)分别为2.29%、1.52%、1.02%、2.05%。结论 该法简便、准确,灵敏度高,稳定性和重复性好,可用于红花药材的质量控制。

Abstract: Objective To establish an HPLC method for the simultaneous determination of hydroxysafflor yellow A, rutin, quercetin, and kaempferol in Carthamus tinctorius L.. Methods The Agilent ZORBAX SB-C18 column (4.6 mm × 250 mm, 5 ?m) was used with diode array detection. The mobile phase was 0.5% phosphoric acid (A) and methanol (B) to separate the four components by gradient elution at 30 ℃; the flow rate was 0.8 mL/min; the injection volumn was 10 ?L; the detection wavelength was at 360 nm. Results The linear ranges of hydroxysafflor yellow A, rutin, quercetin, and kaempferol were 0.077 6–0.776 0 ?g (r=0.999 9), 0.046 0–0.460 0 ?g (r=0.999 6), 0.006 4–0.064 0 ?g (r=0.999 9) and 0.012 8–0.128 0 ?g (r=0.999 7), respectively. The average recoveries of four components were 99.68% with RSD=2.29% (n=6), 99.78% with RSD=1.52% (n=6), 102.03% with RSD=1.02% (n=6), 97.03% with RSD=2.05% (n=6), respectively. Conclusion The method is convenient, accurate, sensitive, stable and repeatable, which can be a method for quality control of Carthamus tinctorius L..

紅花为菊科红花属植物红花Carthamus tinctorius L.的干燥花,始载于《开宝本草》,在我国已有多年栽培和药用历史,主要分布在新疆、河南、四川、云南、浙江等地[1]。红花具有活血化瘀、散瘀止痛、降血压和降血脂等功效[2]。《本草纲目》记载,红花能“活血润燥,止痛散肿,通经”。临床和药理研究发现,红花对心脑血管系统、神经系统、免疫系统等均可发挥一定作用,同时具有抗炎、镇痛、抗肿瘤、抗菌、抗氧化等多种生理活性[3-5]。
红花的化学成分有黄酮、生物碱、聚炔、有机酸和多糖等,其中以黄酮类化合物(红花黄色素)为主要有效成分[6-9]。2015年版《中华人民共和国药典》[10]仅对红花中的羟基红花黄色素A和山柰素进行了含量测定,未对其他成分进行研究。为更好开发和合理利用红花资源,本试验以新疆红花为研究对象,采用HPLC同时测定红花药材中4种化学成分含量,为有效控制药材质量、提高红花质量标准提供依据。
