Due to the limited scientific-based evidence on health properties of A. viridiflora Craib., phenolic compositions, antioxidant activities, and inhibition of the key enzymes relevant to the occurrence of obesity (lipase), diabetes (α-glucosidase and dipeptidyl peptidase-IV (DPP-IV)), hypertension (angiotensin-converting enzyme (ACE)), and Alzheimer’s disease (acetylcholinesterase (AChE), butyrylcholinesterase (BChE), and β-secretase (BACE-1)) were also investigated. The gene discussed is DPP4; the disease is early-onset autosomal dominant Alzheimer disease.
