Greening Ultrasound-Assisted Extraction for Sorghum Flour Multielemental Determination by Microwave-Induced Plasma Optical Emission Spectrometry

<div>(a) Score scatter plots of the first 3 PCs obtained from PCA applied to a dataset corresponding to each mineral content on sorghum samples. The samples are shown according to the hybrids: G sorghum samples (red square), F sorghum samples (green diamond), and DP sorghum samples (light-blue triangle). Explained variance values of PC1, PC2, and PC3 are displayed in the corresponding axis. (b) Loading bar plots of the first 3 PCs obtained from PCA for each variable.</div>
