“…Yellow leaf extract was effective at suppressing hyperglycemia and hepatic steatosis through enhancing adiponectin-receptor signaling AMPK (AMP-activated protein kinase) activation and pancreatic β-cell functionality [ 20 ]. More than 36 phenolic compounds from soybean leaves have been reported, and the main bioactive components are flavonol, isoflavone, pterocarpan, and soyasaponin derivatives [ 21 , 22 ]. Secondary metabolites in the leaves were associated with the growth stage.…”

A Significant Change in Free Amino Acids of Soybean (Glycine max L. Merr) through Ethylene Application

et al. 2021

In this study, the changes in free amino acids of soybean leaves after ethylene application were characterized based on quantitative and metabolomic analyses. All essential and nonessential amino acids in soybean leaves were enhanced by fivefold (250 to 1284 mg/100 g) and sixfold (544 to 3478 mg/100 g), respectively, via ethylene application. In particular, it was found that asparagine is the main component, comprising approximately 41% of the total amino acids with a twenty-five fold increase (78 to 1971 mg/100 g). Moreover, arginine and branched chain amino acids (Val, Leu, and Ile) increased by about 14 and 2–5 times, respectively. The increase in free amino acid in stem was also similar to the leaves. The metabolites in treated and untreated soybean leaves were systematically identified by gas chromatography–mass spectrometry (GC-MS), and partial variance discriminant analysis (PLS-DA) scores and heat map analysis were given to understand the changes of each metabolite. The application of ethylene may provide good nutrient potential for soybean leaves.
