摘要:
Disclosed is a kaempferol preparing method comprising isolating kaempferol from kaempferol glucosides using an acid, a base, an enzyme or a microbe producing the enzyme. More specifically, the method comprises obtaining a plant extract containing kaempferol glycosides from a plant using water or an organic solvent; and hydrolyzing the plant extract using an acid, a base, an enzyme or a microbe producing the enzyme to isolate kaempferol. The kaempferol glycosides comprise camelliaside A or camelliaside B. The plant extract is derived from a seed or leaf of green tea. When using the method of the invention, it is possible to mass-produce kaempferol, which is one of main physiological activating ingredients, from a plant, particularly a seed or leaf of green tea.

An object of the present invention is to provide the tocopherol derivatives represented by the following formula (I), and their salts: Wherein, R1, R2 and R3 are H or methyl group, and at least one positions selected from group consisting of the R1, R2 and R3 positions are methyl group; and, A is CH2—CH(CH3)— or CH═C(CH3)— The other object of the present invention is to provide a method for preparing the above tocopherol derivatives. The tocopherol derivatives is prepared by reacting tocopherol with phosphorous oxychloride in an equivalent ratio of 1:1˜1.3, in presence of an organic base, in an organic solvent; reacting the tocopherol dichlorophosphate produced by the above reaction with 3-aminopropanol in presence of an organic base, in an organic solvent; and, hydrolyzing the above products. The tocopherol derivatives according to the present invention can be hydrolyzed by biological enzymes in a living body to produce tocopherol and 3-aminopropane phosphate. And they can induce physiological activities including recovery of injured skin, prevention from aging of bio-membrane, etc. Also, the tocopherol derivatives according to the present invention have improved stability, safety to skin and anti-oxidant effect superior to preceding tocopherol and its derivatives.
