Although various kinds of natural antioxidants have recently been reported, only tocopherol is used as an antioxidant. On the other hand, synthetic antioxidants BHT (butylated hydroxytoluene) and BHA (butylated hydroxianisole), which are widely used due to their excellent antioxidant power and low price, are known to cause serious illness when ingested in excess and are toxic to humans and are being regulated for use. . On the other hand, alpha-tocopherol and ascorbic acid, which are used as natural antioxidants, have the disadvantage of low antioxidant effect and relatively high price, and thus are safer and more potent natural antioxidants. Is urgently needed.

Reports on antioxidants studied so far include the antioxidant effects of ginkgo biloba, bear odor, brown root, green tea and dandelion extract.

Saeda japonica is an annual plant of the family Ming Dynasty and is distributed in the intertidal zone of the west coast of Korea. It is the representative species of the Sino-Japanese group among the world-class coastal vegetation. The plants in the genus Suaeda are typical salt plants, which are plants that grow on the beach, in salt lakes, and in salt rock. In addition, because many salts are contained in the cell, the osmotic pressure is high, so it can suck water even when the soil solution has a high penetration. These plants, which are not only capable of growing in high-salt areas, but also contain large amounts of natural minerals, are thought to be rich in secondary metabolites, which are highly bioavailable to other organisms, and thus have potential applications as functional materials.

<Test Example 1> Method of measuring the antioxidant activity of the extract

DPPH (1,1-diphenyl-2-picryl-hydrazyl) radical scavenging ability was measured by the method of Blois (Blois MS. 1958. Antioxidant activity determination by the use) of a stable free radical.Nature 181: 1199-1200).

1 mL of 0.2mM DPPH (Sigma Co., St Louis, MO) was added to 1 mL of each sample of the extract of St. John's wort, allowed to stand for 30 minutes at room temperature, and then the reaction solution was prepared at 517 nm using a spectrophotometer (UV 1600 PC). Absorbance was measured. DPPH radical scavenging ability was converted by the following formula.

DPPH radical scavenging ability (%) = [1- (sample addition absorbance / sample no addition absorbance)] × 100

As shown in Fig. 1, the DPPH radical scavenging activity of the tannincho butanol extract, which was not irradiated, that was obtained by irradiating a gamma ray dose of 0 kGy, was 77.46%, and ethyl acetate, methanol and water ), Radical scavenging ability of 74.43%, 47.99%, and 27.70%. However, the DPPH radical scavenging ability of the extracts from the extracts of the turkey extract obtained by investigating the gamma-ray dose of 50 kGy was 85%, 82%, 50%, 57%, and 34% in the butanol extract, ethyl acetate extract, methanol extract, and water extract, respectively. Increased value was obtained in comparison with the extract of N. chinensis.

Therefore, it was confirmed that the extract with increased antioxidant activity from turkey vinegar could be obtained by irradiation.

<Test Example 2> Method of measuring the total polyphenol content of the extract

The total polyphenol content of the extracts of the extracts of the turkey extract for each of the extracts of the extract from the extract of Example 2 was determined by the Folin-Ciocalteu method (Gao X, Bjork L, Trajkovski V, Uggla M. 2000. Evaluation of antioxidant activities of rosehip ethanol extracts in different test system.J Sci Food Agric 80: 2021-2027.).

0.2 mL of Folin-Ciocalteu's reagent (Sigma Co., St Louis, Mo.) was added to 0.1 mL of each sample of the extract of the turkey vinegar, and maintained at 23 ° C. for 1 minute. Thereafter, 3 mL of 5% sodium carbonate was added thereto, and the mixture was left at 23 ° C. for 2 hours, and then absorbance was measured at 765 nm using a spectrophotometer (UV 1600 PC, Shimadzu, Tokyo). The standard curve was used to calculate the calibration curve after preparing the calibration curve using gallic acid (Sigma).

2 shows the results of measuring polyphenol content of the extracts of each of the seven extracts of the seven fractions prepared in Example 2. Polyphenol content of ethyl acetate extract was measured as 21.33mg / g, which was the highest among the fractions. Next, butanol and methanol extracts were in the order of 17.31mg / g, 2.33mg / g, and polyphenol was not detected in the water extract. However, the polyphenol content of the extracts of the extract from the tannincho extract obtained by investigating the gamma-ray dose of 50 kGy was 24.5 mg / g, 20.6 mg / g and 2.76 mg / g in ethyl acetate, butanol and methanol, respectively. But it can be seen that there is a polyphenol content. Therefore, it was confirmed that the extract with increased polyphenol content can be obtained from the turkey herb using radiation.
