Citron Extract, Flavonoids
Description
Embodiments of the present invention relates to a cosmetic composition comprising a citron extract.
Citron is a kind of citrus produced in Northeast Asia including Korea, China and Japan. Korea has the strongest fragrance and thickest skin. Korea's major producing regions are Goheung, Wando, Jangheung, Jindo, and Jeju Island, Jeollanam-do.
As the main ingredient of citron, vitamin C contains three times more than lemon, which is good for colds and skin care, and contains many organic acids that prevent aging and fatigue. In addition, vitamin B, sugars, and protein are more than other citrus fruits and contain flavonoids that protect capillaries, thereby preventing cerebrovascular disorders and wind. It also drains and excretes the waste that builds up in the body.
Flavonoid and limonoid compounds present in citrus fruits have a very high bioactive effect. Flavonoids such as naringenin, hesperidin, and nobiletin in citron seeds have been reported to be effective in treating colorectal cancer. It has also been reported to inhibit expression and inhibit lymph node or lung metastasis of these tumors. In addition, it has been reported that citrus flavonoids inhibit the activity of tumor growth promoters, and also inhibit the activity of anticancer drug resistance genes of cancer cells that pump out therapeutic drugs entering cancer tissues.
There are also studies showing that flavonoid compounds lower blood cholesterol levels and that citrus flavonoids have antiviral, antibacterial and antifungal effects by acting like vitamins. Citrus limonoid compounds, in particular, limonin (limonin) and nomilin (nomilin) has been reported to suppress stomach cancer, lung cancer, skin cancer, etc. Recently, studies have been reported to effectively inhibit breast cancer.
According to the domestic functional cosmetics law, functional cosmetics are defined as having an effect on anti-aging wrinkle prevention, whitening, and skin protection against ultraviolet rays. Skin aging can be divided into photoaging observed in skin exposed to ultraviolet rays for a long time and intrinsic aging (chronological aging) observed in non-exposed areas, and more than 70% of the causes of skin aging are caused by photoaging. have. Ultraviolet rays are known to have the greatest effect on skin aging, among other energy sources from the sun. The effect of ultraviolet rays is that wrinkles are formed when UV rays are irradiated to hairless mice. Also, when UV rays are irradiated to cultured fibroblasts, expression of collagen (procollagen), which is a skin protein, decreases and MMP- The importance of 1 expression is increased.
Basically, all functional cosmetics use functional physiologically active materials that can prevent skin damage to ultraviolet rays. Recently, the global trend of technological development is actively developing antioxidant materials obtained from natural products. Therefore, it is possible to develop ultraviolet light products using known components of citron hesperidin, carotenoids and vitamin C. In particular, hesperidin has a great potential as a novel flavonoid.
Numerous studies have been published in addition to those illustrated above that the flavonoid and limonoid compounds present in citrus fruits have a very high physiological activity. Seeds in particular are known to contain much more of these substances than rinds and tissues. However, in the country, the use of citron is mainly used for the production of citron, and the seeds which occupy about 10-15% of the whole fruit are disposed of all 1,800 tons per year.
Therefore, the development of a new functional cosmetic material using citron seed extract, which is a citron by-product, is likely to be converted into a high value-added product from industrial waste to a new functional cosmetic, and thus, it is very necessary to develop a new functional cosmetic material through citron seed extract.
