摘要:
为了鉴别不同纯度的青蒿素样品,本文运用正交偏最小二乘法判别分析方法(OPLS-DA)研究了不同纯度青蒿素样品的拉曼光谱。研究表明,对青蒿素拉曼光谱进行OPLS-DA建模分析可以鉴别不同纯度的样品,从而用于青蒿素样品的质量评估。另外,青蒿素拉曼光谱OPLS-DA建模分析表明,青蒿素拉曼光谱中与生物活性官能团相关的724 cm-1处的特征振动模式与青蒿素的纯度紧密相关:在不同纯度青蒿素样品中,该特征振动模式与其他振动模式的相对强度比具有统计学差异(单向方差分析,F=7.39,P<0.01)。
Abstract:
To differentiate the purity of artemisinin samples, this paper uses orthogonal projections to latent structures-discriminant analysis (OPLS-DA) modeling to sudy Raman spectra of artemisinins with different purities. The results showed that OPLS-DA modeling provides a promising tool to differentiate the purity of artemisinin samples, which would be useful for practical application in quality evaluation of artemisinins. Also, the OPLS-DA modeling on Raman spectra showed that the characteristic vibrational mode at 724 cm-1 correlated with the bioactive functional group is very sensitive to purity of artemisinin. In addition, it was demonstrated that the relative intensity ratio of 724 cm-1 to a mode not correlated with the bioactive functional group is statistically different (one-way ANOVA, F=7.39, P<0.01) among different artemisinin samples.
