[Industrial Application Field] The present invention relates to an antioxidant, particularly an antioxidant suitable for oils and fats and oils having unsaturated bonds and susceptible to rancidity. [Prior Art] Conventionally, oils and fats such as olive oil and castor oil, or oils that have unsaturated bonds and are susceptible to rancidity, have been blended with antioxidants that have antioxidant ability for the purpose of improving storage stability. However, the current situation is that the use of synthetic antioxidants such as BHT and BHA is being reconsidered, especially from a safety standpoint. Against this background, demand for vitamin E as a natural antioxidant is increasing, but there are problems with its source, solubility in base materials, price, etc.
There is a strong need for the development of new natural antioxidants. [Problems to be Solved by the Invention] The present inventors have made extensive studies in view of the above circumstances, and have found that saponin extracted from loofah has an excellent antioxidant ability that is comparable to that of vitamin E. Based on this finding, we have completed the present invention. [Means for Solving the Problems] That is, the present invention is an antioxidant containing saponin extracted from loofah as an active ingredient. Hereinafter, the configuration of the present invention will be explained in detail. Saponin obtained by extraction from loofah used in the present invention (hereinafter referred to as loofah saponin) is obtained by extracting the above-ground or underground parts of loofah with a solvent such as water, lower alcohol, hydrous lower alcohol, etc. After the above extract is concentrated, it is purified using an adsorption method or a distribution method, and then dissolved in a water-soluble solvent such as a lower alcohol, and then ether or n-
If it is added to a fat-soluble solvent such as hexane and collected as a precipitate, highly pure loofah saponin can be obtained. The main active ingredients of the loofah saponin are lucioside A, lucioside B, lucioside C, lucioside D, lucioside E, lucioside F, lucioside G, lucioside H, and lucioside I, which are shown by the following structural formula, and in addition, ginsenoside Re, It is known to contain ginsenoside Rg 1 ,
The structures of individual luciosides have been disclosed in Japanese Patent Application No. 155552/1983. Furthermore, ginsenoside Re and ginsenoside Rg 1 are known substances. Lucioside A; R 1 = CH 2 OH, R 2 = β-D-glucopyranoside, R 3 = OH, R 4 = H Lucioside B; R 1 = CH 2 OH, R 2 = β-D-glucopyranoside, R 3 = H, R 4 = OH Lucioside C; R 1 = CH 3 , R 2 = β-D-glucopyranoside, R 3 = OH, R 4 = H Lucioside D; R 1 = CHO, R 2 = β-D-glucopyranoside, R 3 = H, R 4 = OH Lucioside E; R 1 = CH 2 OH, R 2 = β-D-glucopyranoside, R 3 = H, R 4 = H Lucioside F; R 1 = CHO, R 2 = β- D-glucopyranoside, R 3 = H, R 4 = H Lucioside G; R 1 = CH 3 , R 2 = β-D-glucopyranoside, R 3 = H, R 4 = OH Lucioside H; R 1 = CH 3 , R 2 = β-D-glucopyranoside, R 3 = H, R 4 = H Lucioside I; R 1 = CH 2 OH, R 2 = H, R 4 = OH. It can be isolated by fractionation using Naturally, in the present invention, the lucioside thus obtained may be used alone. By dissolving loofah saponin and individual luciosides in a small amount of lower alcohol, they can be freely dissolved in both water and oil, and have a wider range of applications than vitamin E. The blending amount of one or more of Hetimasaponin, Lucioside A, Lucioside B, Lucioside C, Lucioside D, Lucioside E, Lucioside F, Lucioside G, Lucioside H, and Lucioside I is preferably 0.001 to 5% by weight based on the fat and oil. is 1~
It is 2% by weight. The antioxidants of the present invention are oils and fats that are susceptible to rancidity, such as olive oil, castor oil, camellia oil, tea seed oil, avocado oil, sesame oil, cottonseed oil, wheat germ oil, sunflower oil, soybean oil, safflower oil, evening primrose oil, and medfoam. It is used for unsaturated fatty acids such as linoleic acid, linoleic acid, and oleic acid, their esters, and oils with unsaturated bonds such as unsaturated alcohols. All kinds of food products, such as edible oil, dairy products, margarine, lard, meat products,
It is effective when used in canned foods, seafood, instant foods, confectionery, soft drinks, as well as paints, pigments, medicines, cosmetics, etc. [Effects of the Invention] The antioxidant of the present invention is an antioxidant of natural origin, has no safety concerns, and can be expected to be obtained at a lower price than vitamin E, which is a conventional natural antioxidant. Moreover, the problem of supply can be solved by cultivating loofah. Furthermore, by dissolving both loofah saponin and individual luciosides in a small amount of lower alcohol,
It can be freely dissolved in both water and oil, and has a wider range of applications than vitamin E. In addition, its antioxidant ability is as good as that of vitamin E. [Example] Next, the present invention will be explained in more detail with reference to Examples. Example 1 Loofa saponin (0.6 mg,
2mg or 5mg) and dissolve. this thing
After storage for 3 or 6 days in a constant temperature bath at 50°C, the peroxide value (POV) was measured according to the oil chemistry method. As a control, ethyl linoleate without the addition of loofah saponin and ethyl linoleate to which 2 mg of tomicostocopherol (vitamin E analogue, manufactured by Eisai) were added were used. The results are shown in Table-1.
