摘要（英）：

The invention provides a preparation method of turmeric extract. The turmeric extract is prepared from radix curcuma through crushing, alcohol extraction, concentration, extraction, crystallization, washing and drying. The product has a gorgeous color. The turmeric extract contains 45.0%-70.0% of curcumin (C21H20O6), demethoxycurcumin (C20H18O5) and bisdemethoxycurcumin (C19H16O4), the total ratioof the curcumin (C21H20O6), demethoxycurcumin (C20H18O5) and bisdemethoxycurcumin (C19H16O4) is greater than the curcumin compound content of 93.0% and the content of compound (C21H20O6) is 40.0%-60.0%. The product fully satisfies the requirements on use of soft capsules with effects of reducing blood fat and dredging collaterals. The method utilizes a one-step extraction method and a two-step alcohol precipitation method, ensures the quality of the turmeric extract, has simple processes, realizes obvious oil removal effects, is conducive to product drying, has stable processes and is suitable for industrial production.
