摘 要 目的:建立同时测定经典名方槐花散中芦丁、柚皮苷、新橙皮苷、槲皮素和胡薄荷酮等5种成分含量的方法。方法:采用高效液相色谱波长切换法。色谱柱为Cosmosil C18,流动相为乙腈-0.05%磷酸溶液(梯度洗脱),检测波长依次为257 nm(芦丁)、283 nm(柚皮苷、新橙皮苷)、254 nm(槲皮素)、252 nm(胡薄荷酮),流速为1.0 mL/min,柱温为30 ℃,进样量为10 μL。结果:芦丁、柚皮苷、新橙皮苷、槲皮素、胡薄荷酮检测质量浓度的线性范围分别为21.7~2 170、46~4 600、22.3~2 230、0.96~96、2.7~270 μg/mL(r均大于0.999);精密度、稳定性(24 h)、重复性试验的RSD均小于2%(n=6);平均加样回收率分别为100.70%、99.31%、101.10%、100.03%、99.63%(RSD均小于2%,n=9)。3批槐花散样品中,上述5种成分的含量分别为20.055~22.615、25.557~27.806、11.428~13.250、0.350~0.478、2.372~4.011 mg/g。结论:所建含量测定方法操作简便、结果准确、重复性好,可用于槐花散中5种成分的同时测定。

ABSTRACT OBJECTIVE: To develop a method for simultaneous determination of 5 components in classical formula Huaihua san, including rutin, naringin, neohesperidin, quercetin and pulegone. METHODS: HPLC wavelength switching method was adopted. The determination was performed on Cosmosil C18 column with mobile phase consisted of acetonitrile-0.05% phosphoric acid solution (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelengths were set at 257 nm for rutin, 283 nm for naringin and neohesperidin, 254 nm for quercetin, 252 nm for pulegone, respectively. The column temperature was set at 30 ℃, and sample size was 10 μL. RESULTS: The linear range was 21.7-2 170 μg/mL for rutin, 46-4 600 μg/mL for naringin, 22.3- 2 230 μg/mL for neohesperidin, 0.96-96 μg/mL for quercetin, 2.7-270 μg/mL for pulegone (all r>0.999), respectively. RSDs of precision, stability (24 h) and reproducibility tests were all lower than 2% (n=6). Average recoveries were 100.70%, 99.31%, 101.10%, 100.03% and 99.63% (all RSD<2%, n=9). Among 3 batches of Huaihua san samples, the contents of above 5 components were 20.055-22.615, 25.557-27.806, 11.428-13.250, 0.350-0.478, 2.372-4.011 mg/g, respectively. CONCLUSIONS: Established method is simple, accurate and reproducible, and could be used for the simultaneous determination of 5 components in Huaihua san.

槐花散始载于宋代许叔微所著的《普济本事方》,是治疗肠风脏毒的经典方[1]。该方为《古代经典名方目录(第一批)》第34方,具有清肠凉血止血、疏风行气的功效,主治风热湿毒、壅遏肠道、损伤血络证,常用于溃疡性结肠炎的临床治疗[2]。槐花散由槐花(炒)、侧柏叶(烂杵焙)、荆芥穗、枳壳(去穰细切,麸炒)等4味药材组成,依据文献[3-6]和2020年版《中国药典》(一部)[7],该方主要含有黄酮类(如槐花所含的芦丁和槲皮素、侧柏叶所含的槲皮苷、枳壳所含的柚皮苷和新橙皮苷)和单萜类(如荆芥穗所含的胡薄荷酮)成分。现代研究表明,上述6种成分均具有抗炎作用[8-11]。……p>
