preparation example 1

[0046] Preparation Example 1: Preparation I of Magnolia Magnolia Extract

[0047] 200 g of Magnolia flowers washed with purified water and dried were added to 1.2 L of water, and extracted by heating at 70-90° C. for 5 hours in an extractor equipped with a cooling condenser. Then, the extract was filtered through a 300-mesh filter cloth, aged by standing at 5-10° C. for 7-10 days, and then filtered through Whatman No. 5 filter paper. The filtrate was dried on a rotary vacuum evaporator at 65°C to obtain a dry weight of 10.8 g.

People lacking this pigment are very sensitive to sunlight, making them more likely to burn. Also, even at a young age, there is a high risk of developing skin cancer. It is known that short-wavelength ultraviolet rays (290-320nm) and carcinogens form harmful free radicals on the skin, for example, oxygen free radicals, and that the oxygen free radicals attack skin cells to age the skin. The main function of melanin is to eliminate this harmful free radical, thereby protecting the skin from the damage caused by this harmful free radical. Therefore, people with a lot of melanin have an effective defense system that can protect the skin from physical or chemica...
