The invention discloses a tea saponin high-grade fatty ester as well as a preparation method and an application thereof. The tea saponin high-grade fatty ester has the structure disclosed in the formula I and is prepared by the following method: in the presence of a catalyst, mixing tea saponin with high-grade fatty ester to react, and separating the catalyst to obtain the tea saponin high-grade fatty ester disclosed in the formula I. The tea saponin high-grade fatty ester is made of natural raw materials, is nontoxic and is easy to degrade. The tea saponin high-grade fatty ester has simple preparation technology and easily-controlled reaction conditions and can be used for industrial production. What is more important is that the tea saponin high-grade fatty ester has stronger foaming power and foam stabilization performance at high temperature and in oil when the fatty ester serves as a surfactant. The tea saponin high-grade fatty ester overcomes the defect that the existing tea saponin has poor foaming pow
