Stabilized compositions of aqueous reduced coenzyme Q solution
View Patent ↗The present invention provides a reduced coenzyme Q-containing solution capable of being retained more stably against oxidation, by using a reduced coenzyme Q which is hydrophobic and susceptible to oxidation and thus unstable. The aqueous solution containing a reduced coenzyme Q obtained in the present invention is a solution containing a reduced coenzyme Q and an antioxidant such as vitamin C and/or a chelating agent such as ethylenediaminetetraacetic acid.
1. An aqueous solution, comprising:
a reduced coenzyme Q represented by the following formula (1):
in the formula, n represents an integer of 1 to 12;
a liposome containing the reduced coenzyme Q; and
ethylenediaminetetraacetic acid or a salt thereof in an amount effective to stabilize said reduced coenzyme Q.
2. The aqueous solution according to claim 1 ,
wherein the liposome further contains ethylenediaminetetraacetic acid or a salt thereof.
3. The aqueous solution according to claim 1 ,
wherein the reduced coenzyme Q is reduced coenzyme Q 10 .
