Assessing the Quality of Calyx of <i>Physalis alkekengi</i> L. var. <i>franchetii</i> Based on Quantitative Analysis of Q-Marker Combined with Chemometrics and Machine Learning Algorithms

<div>3D PLS-DA score plot of PALF. (a) PLS-DA of the samples (G1: the samples are brightly colored and almost free of moths and mold; G2: the samples are brown or dark brown and have different degrees of mold or are moth-eaten). (b) PLS-DA of G2 (g1: the samples are dark brown, moldy, or severely moth-eaten; g2: the samples are light brown, with slight mildew, or are moth-eaten).</div>
