摘要:

采用非线性化学指纹图谱技术获得了石菖蒲、 水菖蒲和九节菖蒲的特征指纹图谱, 直观差异明显; 将石菖蒲分别与水菖蒲和九节菖蒲进行二元掺杂, 利用指纹图谱定量信息和各菖蒲含量拟合得到线性回归方程, 相关系数>0.9990. 用该方程预测了二元混合物中不同菖蒲的含量, 相对误差≤4.17%, RSD≤2.73%. 非线性化学指纹图谱技术具有良好的重现性和特征性, 同种菖蒲指纹图谱间系统相似度≥0.9989, 不同种菖蒲指纹图谱间相似度≤0.9123. 此外, 该技术摒弃传统方法复杂的前处理过程, 可高效、 快速进行鉴别, 从整体性角度对样本进行定性鉴别与定量分析.

Abstract:

As a common medicine, the price of Grass-leaved sweetflag differs greatly from those of Rhizoma calami and Acorus graminens soland, so the phenomenon of mixed or substituted use always appear in the market. In this paper, characteristic fingerprints of Grass-leaved sweetflag, Rhizoma calami and Acorus graminens soland were obtained by nonlinear chemical fingerprint technique and their visual difference was obvious. The binary doping of Grass-leaved sweetflag with Rhizoma calami and Acorus graminens soland was carried out, the linear regression equation was obtained via the quantitative information of the fingerprints and the content of calamus, the correlation coefficient was >0.9990. Using this equation to predict the content of each calamus in a mixture consisting two species of Acorus calamus. the relative error≤4.17%, RSD≤2.73%. The nonlinear chemical fingerprinting technique has a good reproducibility and characteristic. The system similarities of the fingerprints between the same species of Acorus calamus are ≥0.9989, while those of different species of Acorus calamus are ≤0.9123. In addition, the technology abandons the complex traditional pre-processing methods with high efficiency and fast peculiarity, and can be used to identify, analyze and evaluate the samples in a holistic.
