The nutritional characteristics and functionalities of the polyplant extracts(PPE) from the extraction of various plants were assessed for the development of a new functional food. The PPE contained 42.95 g of glucose, 22.61 g of fructose, and 12.48 g of sucrose per 100 g of PPE as free sugar, and its reducing sugar contents was measured at 480.6 mg per g of PPE. Among free amino acids, proline contents was the highest at 0.58 g per 100 g of PPE, and it contained only 12.65 mg of malic acid and 6.92 mg of tartaric acid per g of PPE as an organic acid. The antioxidant activity of PPE was the highest at 91.6%, whereas SOD-like activity and xanthin oxidase inhibitory activity, which are associated with anti-aging effects, were 21.6% and 9.3%, respectively. HMG-CoA reductase inhibitory activity was 10.0% and anti-dementia acetylcholinesterase inhibitory activity was quite low(5.1%).
