摘 要 目的:建立同時測定大黃?蟲丸中17種質(zhì)量標志物含量的方法。方法:采用高效液相色譜(HPLC)法測定10批市售大黃?蟲丸中尿囊素、次黃嘌呤、紅景天苷、羥基芍藥苷、甘草苷、異甘草苷、黃芩苷、對甲氧基苯乙酸、漢黃芩苷、肉桂酸、芹菜素、柚皮素、去甲漢黃芩素、蘆薈大黃素、大黃酸、白楊素、大黃素等17種質(zhì)量標志物的含量。色譜柱為Kromasil 100-5-C18(250 mm×4.6 mm,5 μm),流動相為0.1%磷酸溶液-乙腈(梯度洗脫),流速為1.0 mL/min,柱溫為30 ℃,檢測波長為210 nm,進樣量為20 μL。結(jié)果:上述17種質(zhì)量標志物的質(zhì)量濃度依次在5.74~183.53、6.51~208.24、4.30~137.65、4.60~147.06、4.12~131.76、4.25~135.88、6.31~201.76、4.60~147.06、1.94~62.06、4.47~142.94、0.69~22.06、2.29~73.24、2.33~74.41、1.42~45.29、6.65~212.94、1.11~35.44、1.47~47.06 μg/mL范圍內(nèi)與各自峰面積呈良好的線性關(guān)系(R2均不小于0.999 0)。該方法精密度、重復性、穩(wěn)定性、耐用性的RSD均小于2%(n=6);17種質(zhì)量標志物的平均加樣回收率范圍為96.31%~101.73%,RSD均小于3%(n=6)。結(jié)論:本方法簡便、快速,專屬性、精密度、重復性、穩(wěn)定性、準確度和耐用性均良好,可用于完善大黃?蟲丸的質(zhì)量標準。

ABSTRACT ? OBJECTIVE: To establish the method for the content determination of 17 quality markers in Dahuang zhechong pills (DHZCP). METHODS: HPLC method was adopted to determine the contents of 17 quality markers in 10 batches of DHZCP, such as allantoin, hypoxanthine, salidroside, hydroxypaeoniflorin, glycyrrhizin, isoglycyrrhizin, baicalin, p-methoxyphenylacetic acid, wogonin, cinnamic acid, apigenin, naringin, norwogonin, aloe emodin, rhein, chrysin, emodin. The determination was performed on Kromasil 100-5-C18 (250 mm×4.6 mm, 5 μm) column with mobile phase consisted of 0.1% phosphoric acid solution-acetonitrile (gradient elution) at the flow rate of 1.0 mL/min. The column temperature was 30 ℃, the detection wavelength was 210 nm and the sample size was 20 μL. RESULTS: The linear range of above 17 quality markers were 5.74-183.53, 6.51-208.24, 4.30-137.65, 4.60-147.06, 4.12-131.76, 4.25-135.88, 6.31-201.76, 4.60-147.06, 1.94-62.06, 4.47- 142.94, 0.69-22.06, 2.29-73.24, 2.33-74.41, 1.42-45.29, 6.65-212.94, 1.11-35.44 and 1.47-47.06 μg/mL, respectively (all R2≥0.999 0). RSDs of precision, repeatability, stability and durability tests were all less than 2% (n=6); average recovery of 17 quality markers ranged from 96.31% to 101.73%, and the RSDs were less than 3% (n=6). CONCLUSIONS: The method is simple, rapid, speific, specise, reproducible, stable, accurate and durable, and can be used for improving the quality standard of DHZCP.
