采用正交函数分光光度法测定甲硝唑霜的含量，可消除其中尼泊金乙酯及基质的干扰，直接测定甲硝唑的含量，平均回收率为１００．１０％（ｎ＝５），相对标准偏差（ＲＳＤ）为０．２３％。
The metronidazole cream content was determined by orthogonal function spectrophotometry, which could eliminate the interference of ethyl paraben and matrix. The metronidazole content was determined directly with the average recovery of 100.10% (n = 5) The relative standard deviation (RSD) was 0.23%.
