运用导数光谱对8种葶苈子及其混用品进行了鉴别研究,发现2种正品药材的导数光谱基本一致,而6种混用品则与正品有显著区别。 Using derivative spectra for the identification of eight species of wolfberry fruit and their mixed products, it was found that the derivative spectra of the two authentic medicinal materials were basically the same, while the six mixed products were significantly different from the genuine products.
