TITLE:
摘要: 目的:建立同时测定藏药洁白丸中没食子酸、丁香酚、土木香内酯、异土木香内酯含量的方法。方法:采用高效液相色谱法。色谱柱为CAPCELL PAK MGⅡ C18,流动相为甲醇-乙腈-0.2%磷酸溶液(梯度洗脱),流速为0.8 mL/min,检测波长为220 nm(土木香内酯、异土木香内酯)和280 nm(没食子酸、丁香酚),柱温为30 ℃,进样量为10 μL。结果:没食子酸、丁香酚、土木香内酯、异土木香内酯检测质量浓度线性范围分别为46.50~2 325.00、21.28~1 064.00、4.38~219.20、4.17~208.40 μg/mL(r均≥0.999 1),检测限分别为0.26、0.09、0.28、0.35 μg/mL,定量限分别为0.74、0.25、0.95、1.06 μg/mL;精密度、稳定性(48 h)、重复性试验的RSD均≤2.0%(n=6或n=7),加样回收率分别为98.5%、97.6%、97.1%、101.6%,RSD分别为1.4%、1.9%、1.6%、1.7%(n=6);6批洁白丸样品中没食子酸、丁香酚、土木香内酯、异土木香内酯含量范围分别为4.28~7.02、1.09~4.90、0.25~0.60、0.30~0.72 mg/g。结论:建立的方法可用于藏药洁白丸中没食子酸、丁香酚、土木香内酯、异土木香内酯含量的同时测定。
ABSTRACT: OBJECTIVE: To establish a method for content determination of gallic acid,eugenol,alantolatone and isoalantolactone in Tibetan medicine Jiebai pills simultaneously. METHODS: HPLC method was adopted. The separation was performed on CAPCELL PAK MGⅡ C18 column with of mobile phase composed of methanol-acetonitrile-0.2% phosphoric acid solution (gradient elution) at the flow rate of 0.8 mL/min. The detection wavelengths were 220 nm for alantolatone and isoalantolactone, 280 nm for gallic acid and eugenol.  The column temperature was at 30 ℃, and sample size was 10 μL. RESULTS: The linear ranges of gallic acid,eugenol,alantolatone and isoalantolactone were 46.50-2 325.00, 21.28-1 064.00, 4.38-219.20 and 4.17-208.40 μg/mL, respectively (all r≥0.999 1). The limits of detection were 0.26, 0.09, 0.28,0.35 μg/mL, and the limits of quantitation were 0.74, 0.25, 0.95, 1.06 μg/mL, respectively. RSDs of precision, stability (48 h) and reproducibility tests were all lower than 2.0% (n=6 or n=7). The recoveries were 98.5%, 97.6%, 97.1% and 101.6%, and RSDs were 1.4%, 1.9%, 1.6%, 1.7% (n=6), respectively. The content of gallic acid,eugenol,alantolatone and isoalantolactone in 6 batches of Baijie pills were 4.28-7.02, 1.09-4.90, 0.25-0.60, 0.30-0.72 mg/g, respectively. CONCLUSIONS: The established method can be used for content determination of gallic acid,eugenol,alantolatone and isoalantolactone in Tibetan medicine Jiebai pills simultaneously.
