偏瘫康复液的质量标准研究

Study on the Quality Standard for Piantankangfu Liquid

目的:建立偏瘫康复液(黄芪、红花、赤芍、川芎、天麻等)的质量标准.方法:采用TLC法为处方中的川芎、赤芍、山楂、黄芪制定了定性鉴别方法;用TLCS法测定了偏瘫康复液中士的宁的含量.结果:薄层图谱斑点清晰,阴性对照无干扰;士的宁点样量在0.88～4.40 μg范围内,呈良好的线性关系(r=0.999).士的宁的平均回收率为98.42%(n=5);RSD为1.42%.结论:方法简便、准确,重现性好,精密度高,可用于偏瘫康复液的质量控制.

Objective:To establish the quality standard for Piantankangfu Liquid (Radix Astragali, Flos Carlhami; Radix Paeoniae Rubra; Rkizoma Chuanxiong; Rhizoma Gastrodiae, etc. ) Methods: Rhizoma Chuanxiong,Radix Paeoniae Rubra, Fructus Crataegi, Radix Astragal in Piantankangfu Liquid were identified by TLC; The content for strychnine in Piantankangfu liquid was determined by TLC scanning. Results: The TLC Spots developed is fairly clear, and the blank test showed no interference. A good linear correlation in the range of 0. 88 to 4. 40 μg of the strychnine (r=0. 999). The average recovery of strychnine (n=5) was 98. 42%, RSD was 1. 42%. Conclusion: The method is simple, accurate and with good repeatability and high precision. The method can be used for quality control of Piantankangfu Liquid.
