The invention discloses a plant-derived composition, comprising, by weight, 30%-50% of a first plant component, 37%-57% of a second plant component, and 5%-20% of a third plant component. The plant-derived composition of the invention has high antioxidant capacity, can efficiently scavenge human free radicals, and can be used as a composite dietary supplement for supplementing essential nutrients for human body.

FIELD OF THE INVENTION

The invention belongs to the technical field of health foods and dietary supplements. In particular, the invention relates to a plant-derived composition with high antioxidant capacity.

BACKGROUND OF THE INVENTION

Free Radical is the intermediate metabolite of various biochemical reactions in human life activities, which has high chemical activity and is an effective defense system of the body. If it cannot be maintained at a certain level, it will affect the life activities of the body. In the process of human metabolism, various kinds of free radicals are constantly produced, including various free radicals will be produced continuously, including Oxygen Radicals, Hydroxyl Radicals, Superoxide anion [O2−] Radicals, peroxynitrite [ONOO−] Radicals and Singlet Oxygen. When these free radicals are excessive in the body, a series of biological reactions will be triggered, leading to physical decline and accompanied by pathological changes. Antioxidants can efficiently scavenge free radicals and prevent or inhibit various disorders or diseases caused by excessive free radicals.

Due to the structural limitation of single-component antioxidant, it can't completely scavenge free radicals with different properties, and its antioxidant activity is low when used alone, and it is easy to produce toxic and side effects when used in large amounts. Through reasonable formula and proportion, various antioxidant components can produce synergistic effect, and the complementary effect of their structure-activity relationship can play a stronger role than a single antioxidant. Composite antioxidants can be regenerated by mutual repair, forming a redox circulation system, so that the antioxidant activity is significantly stronger than that of single antioxidants. However, the antioxidant activity of different structural types is different, and even the antioxidant activity of the same structural type will be affected by the number and position of substituents. The antioxidant synergistic effect or antagonistic effect between antioxidant components is influenced by the structure, concentration and reaction system of antioxidants. Improper proportion will lead to antagonism, and there is a strong correlation between antagonism and its proportion. Therefore, it is of great significance to study the synergistic effect between antioxidants and find a composite natural antioxidant with high efficiency and low toxicity for the efficient use of antioxidants.

At present, the existing antioxidant single component or composition cannot reach a high level of Oxygen Radical Absorbance Capacity for the time being. So, it is urgent to develop a product of plant-derived/plant-based composition with high antioxidant ability to effectively scavenge human free radicals and prevent or inhibit various disorders, diseases, or problems caused by excessive free radicals in the human body, and this kind of product will have a very broad market prospect.
