The invention discloses monohydroxy conjugated linoleic acid, a preparation method and application thereof, which relate to a novel conjugated linoleic acid derivative, namely the monohydroxy conjugated linoleic acid, the preparation method and the application thereof. The compounds are the monohydroxy conjugated linoleic acid obtained by following steps: stirring linoleic acid and selenium dioxide for 0.5 to 2h at a temperature of between 25 and 60 DEG C; continuing stirring to react for 12 to 48 hour; and adding water to wash the obtained product; collecting an organic solvent layer and recovering a solvent, wherein a molecular formula is C18H32O3, and the morphology is yellowish oily matter. The monohydroxy conjugated linoleic acid is used for preparing medicaments or food for treating obesity or reducing blood fat or reducing blood sugar or improving the immunity or resisting tumor, and preparing antioxidative and whitening skin nursing preparations for external application. L-carnitine can also be added into dihydroxyoleic acid to prepare medicaments or food for treating obesity or reducing blood fat or reducing blood sugar or serve as a feed additive, and the weight ratio ofthe monohydroxy conjugated linoleic acid to the L-carnitine in a product is 4:1-8. |
