Method for producing turmeric stable prepn.

Abstract

A process for preparing the high-stability turmeric preparation from the turmeric stem tuber includes such steps as beating to obtain powder, supercritical CO2 separation to separate the non-polar oil-soluble substance and obtain curcumin and curcuma oil, and using polyol to protect them.

Description

Technical field: [0001] The invention relates to a method for extracting active substances from plants to prepare preparations, in particular to a process for preparing stable preparations of turmeric active substances by extracting active ingredients from curcuma plant tubers. Background technique: [0002] Curcuma tubers of the genus Curcuma contain polar yellow pigments, phenolic β-diketone and other compounds, and non-polar oil active ingredients. The phenolic substances are rare curcumol, curcumone, curcumadione, etc. They are powerful trappers of free radicals, and non-polar oils also have medicinal properties. These active ingredients have played important roles in anti-cancer, anti-inflammation, anti-virus, hypolipidemic, beauty and food coloring, and are of great economic value. [0003] However, curcumin is tightly combined with pectin, starch, cellulose and non-polar oils, making it difficult to separate. The residual solvents in traditional organic solvent sepa...
