Huangjing (Polygonati Rhizoma) is a traditional food-medicine substance in China, which can serve as a grain substitute historically. However, its material basis is not starch but agavin-type fructans with dual regulatory effects on energy and biological activity, which also constituted the staple diet component of pre...
