建立吴茱萸碱磷脂复合物复合率的测定方法。采用紫外分光光度法测定游离的吴茱萸碱的含量,从而计算吴茱萸碱磷脂复合物的复合率。结果表明,吴茱萸碱在225nm处有最大吸收,浓度在1.05—4.20μg.mL-1范围内与吸光度呈良好的线性关系,回归方程为:A=0.1776C+0.006,r=0.9997;平均加标回收率为99.71%,RSD为1.26%(n=9)。该法操作简便、精密度好、结果准确可靠。
To establish a method for the determination of evodiamine phospholipid complex compound rate. The content of free evodiamine was determined by UV spectrophotometry to calculate the recombination rate of evodiamine phospholipid complex. The results showed that evodiamine has the maximum absorption at 225nm, the concentration of 1.05-4.20μg.mL-1 range and the absorbance showed a good linear relationship, the regression equation was: A = 0.1776C +0.006, r = 0.9997; average spiked The recovery was 99.71% with a RSD of 1.26% (n = 9). The method is simple, accurate, accurate and reliable.
