目的 建立荣保灵芝1号子实体及其孢子粉中灵芝酸A的含量测定方法。 方法 采用高效液相色谱法，UltimateTM XB-C18色谱柱，柱温：25℃，流速：0.800 mL/min，检测波长：254 nm，流动相为乙腈(B)-0.1%冰乙酸水溶液(A)，梯度洗脱。 结果 灵芝酸A的线性范围是0.010～1.200 mg/mL（r=0.9998），平均回收率为100.55%，相对标准偏差为1.70%（n=6），子实体中灵芝酸A的含量范围在2.221 7～3.531 1 mg/g，孢子粉中灵芝酸A的含量范围在0.167 2～0.742 9 mg/g。 结论 该方法简便，专属性和重复性好，对连续3年采集的荣保灵芝1号子实体和孢子粉中的灵芝酸A进行测定，其含量都随年份的增加而增加。
【摘要】 目的 考察用乌头碱水解物、新乌头碱水解物、次乌头碱水解物的含量作为附片水煎剂及附片质量控制指标的可行性。 方法 采用高效液相色谱分析法，色谱柱为Shimpack CLC-ODS，以甲醇-乙酸铵溶液（0.2 mol/L）（200︰210）为流动相，流速1.0 mL/min，检测波长为241 nm，对乌头碱新，乌头碱、次乌头碱水解物的含量测定进行研究。 结果 3种水解物检测方法测得水解物在进样范围有良好线性关系，重现性好，稳定性好，生药提取时间宜选定为40 min，不同批号的附片中3种水解物含量差别较大。 结论 此方法简便，使用新乌头碱、乌头碱、次乌头碱的水解物作为含附片制剂的质量控制指标是可行的。【Abstract】 Objective To examine the feasibility of regarding the hydrolyzate from aconitine, new aconitine, and hypaconitine to be the decoction of radix aconite and the quality control index. Methods High performance liquid chromatographic method (HPLC) method was adopted. Shimpack CLC-ODS column with UV detection at 241 nm was used. The mobile phase consisted of (200∶210), and the flow rate was 1.0 mL/min. Results The content of the hydrolysis objects in the water decoction and toxicity were correlated with each other, and the contents of hydrolysis were significantly different among different groups of radix aconiti. Conclusion This method is simple, accurate and effective for content research of hydrolyzate from aconitine-type alkaloids in Monkshoo decoction of Radix Aconiti, and it is feasible to take it as the quality control index.
ObjectiveTo establish a method for content determination of ferulic acid in Piwang massage lotion. MethodsHigh performance liquid chromatography was used. The analysis was carried on Diamonsil C18 (150 mm×4.6 mm, 5 μm, Dimma Science and Technology Co. Ltd.) column with mobile phase consisted of methanol-2% acetic acid (32︰68). The column temperature was 30℃. The detection wavelength was 320 nm. ResultsThe responses of ferulic acid liner in range of 4.55-91.00 μg/mL (R2=0.999 9). The average recovery of ferulic acid was 98.78% (relative standard deviation is 2.668%). ConclusionThe method is simple, rapid and good repeatability. It can be used for quality control of Piwang massage lotion
