Application:
1. Applied in food field, various foods are use it as the materials;
2. Applied in pharmaceutical field, it is made into tablet or capsule, which is often used for eat
less and coughing much sputum;
3. Applied in cosmetic field, many sorts of orange peel oil can nourish the skin.
Functions:
1. Hesperidins has antioxidant, anti-inflammatory, hypolipidemic, vasoprotective and anticarcinogenic and cholesterol lowering actions.
2. Hesperidins can inhibit following enzymes: Phospholipase A2, lipoxygenase, HMG-CoA reductase and cyclo-oxygenase.
3. Hesperidins improve the health of capillaries by reducing the capillary permeability.
4. Hesperidins are used to reduce hay fever and other allergic conditions by inhibiting the release of histamine from mast cells. The possible anti-cancer activity of hesperidins could be explained by the inhibition of polyamine synthesis.
