摘要
采用C_(18)键合相反相色谱方法,样品只经加内标定容后即可进样。RSD<2%。最低检出浓度<1μg/ml,所测补骨脂素与异补骨脂素的回收率分别是102.8%和99.5%,线性范围分别是12~200,13~210μg/ml,相关系数均为0.9999。
reversed-phase HPLC method was described for t he
determination of psoralen and isopsoralen in tinct ure ofFructus
Psoraleae. Aftcr adding the internal standard and diluting the sample
to a definite volume,the sample was in-jected and analysed.The RSDs
were within 2%and the minimum working concentrations below 1 μ
g/ml;the averagerecoveries of psoralen and isopsoralen 102.8%and
99.5%respectively and the linear ranges of psoralen and isopso-ralen
12~200μg/ml and 13~210μg/ml(r=0.999) respectively.
