DPP4 and early-onset autosomal dominant Alzheimer disease: is a rich source of naringenin, while other phenolics including apigenin, p-coumaric acid, sinapic acid, and caffeic acid were also detected; (ii) these phenolics led to high antioxidant activities detected in A. viridiflora Craib.; (iii) in vitro health properties targeting inhibition of the key enzymes controlling obesity (lipase), diabetes (α-glucosidase and dipeptidyl peptidase-IV), Alzheimer’s disease (cholinesterases and β-secretase), and hypertension (angiotensin-converting enzyme) might be the result of bioactivities of the phenolics detected in A. viridiflora Craib.
