Embodiment 1

[0124] Example 1: Extracting active ingredients from Chinese Bauhinia

[0125] Preliminary separation of antioxidant active fractions

[0126] In order to extract active ingredients with antioxidant activity from Chinese Bauhinia, according to the figure 1 Experiments are performed on the process presented in the schematic. Specifically, 1 Kg of leaves and stems of Bauhinia sinensis overcast was crushed into a powder using a pulverizer, and the powder was extracted twice with ethanol (EtOH) at room temperature with two weeks between the two times. To this extract, 0 to 100% ethanol was gradually added thereto (10% increments each time) to prepare an ethanol solution. The prepared ethanol solution was used for extraction. By using DPPH (1,1-diphenyl-2-Pycryl-hydrazine) (Taco, T. et al., Biosci.Biotech.Biochem., 1994,58,1780-1783; Na, M.K. et al., Nat.Prod .Sci., 2002, 8, 26-29) method to study the antioxidant activity of the extract. DPPH is a stable free radical that ...

Embodiment 2

[0167] Embodiment 2: the test of scavenging DPPH free radical activity

[0168] In order to study the antioxidant activity of the extracts isolated in the above-mentioned Example 1 and containing the compounds represented by -, their DPPH free radical scavenging activity was measured by the same method used in the above-mentioned Example 1 . At this time, BHA (tert-butyl-4-hydroxyanisole) and α-tocopherol, a synthetic antioxidant, were used as positive controls.

[0169] As a result, phenolic acids and flavonoids showed dose-dependent strong free radical scavenging activity. However, 1,2-stilbene compounds showed strong free radical scavenging activity. In particular, gallic acid esters including gallic acid have strong activity. For example, the IC of a compound represented by 50 The values ​​are 5.1±0.4, 5.3±0.3, 7.0±1.1, 6.8±0.5, 6.7±0.4 and 8.6±0.7g / ml: (gallic acid), (methyl gallate), (ethyl gallate), ((-)-epicatechin (epicatechin)-3-O-gallate), ((-)-epicatech...

Embodiment 3

[0173] Example 3: Test of Inhibitory Activity of Lipid Peroxidation

[0174] In order to measure the antioxidant activity of the compounds isolated in Example 1 above and containing the compounds represented by to , the lipid peroxidation inhibitory activity of these compounds was investigated. Lipid oxidation produces oxides such as lipid hydroperoxides, conjugated fatty acids (HODEs), epoxy fatty acids, propionaldehyde (MDA) and 4-hydroxynonenal (4-HNE), thus leading to Direct damage to the biofilms that make up cells or indirect reactions with other cellular components. Therefore, lipid oxidation is considered to be one of the main causes of degenerative diseases and aging (Esterbauer, H. et al., FreeRadic.Biol.Med., 1991, 11: 81-128; Esterbauer, H., Cheeseman, K.H., Methods Enzymol ., 1990, 186: 407-421; Jira, W., et al., Chem. Phys. Lipids, 1996, 84: 165-173; Jira, W. et al., Biosci, 1998, 53: 1061-1071). Normally, superoxide radicals generated in the cell's electron...

Abstract

The present invention relates to extract of Cercis chinensis having anti-oxidant activity and antiaging activity containing compound of chemical formula 1 to chemical formula 20, and cosmetical composition for anti-oxidation, skin-aging protection and wrinkle improvement containing the extract as effective ingredient. The extract of present invention having protective effect on oxidative damage and skin damage, and inhibitory effect on age-dependent telomere shortening, so it can effectively used as skin-aging protection comestic.

Description

technical field [0001] The present invention relates to a plant extract having anti-aging activity and a cosmetic composition containing the extract as an effective ingredient. More specifically, the present invention relates to an extract of Chinese Bauhinia (Cercis chinensis) having antioxidant activity and antiaging activity, and to a cosmetic composition containing the extract as an active ingredient, which is useful for antioxidant, Skin aging protection and wrinkle improvement. Background technique [0002] Aging refers to all the physiological changes in the body that occur over time, and the extent and rate of aging varies from individual to individual and is influenced by a variety of causes. Even within an individual, aging manifests itself differently for each organ, so individual-oriented aging studies have limitations. More specifically, the function of every organ and tissue changes over time, a condition that is caused by changes in cellular function. For e...
