Problems solved by technology

[0004] When extracting at low temperature, there is a problem that components that need to be extracted at high temperature or after a long period of storage cannot be effectively extracted, which may also cause economic problems such as a decrease in process efficiency
[0005] As mentioned above, the existing extraction process is limited in the effective utilization of raw materials due to the limitation of the yield and function of the individual single process

preparation example Construction

[0028] The preparation method of turmeric (Curcuma xanthorrhiza Roxb.) extract according to the present invention comprises:

[0029] Step 1), performing supercritical extraction treatment on Curcuma xanthorrhiza Roxb. to obtain a primary extract;

[0030] Step 2), carrying out alcohol extraction or supercritical extraction treatment on the primary extract to obtain a secondary extract;

[0031] Step 3), performing enzyme treatment on the secondary extract to obtain a tertiary extract; and

[0032] Step 4), obtain the residue containing insoluble dietary fiber.

[0033] The supercritical extraction method is a method of extracting using a supercritical fluid. The supercritical fluid refers to a fluid in a state exceeding a critical temperature and a boundary pressure. For example, it can be selected from water, an organic solvent with 1 to 6 carbon atoms and a subcritical or supercritical fluid in the group consisting of more than one solvent to extract the extract. Specifi...

Embodiment 1

[0048] Embodiment 1: supercritical extraction

[0049] 200 g of turmeric (Curcuma xanthorrhiza Roxb.) dried with hot air and ground in 100% CO 2 Under the conditions of 50° C. and 400 bar pressure, a supercritical carbon dioxide extraction device was used to extract for 240 minutes, and 16 g of extract was obtained.

Embodiment 2-1

[0050] Example 2-1: Alcohol Extraction

[0051] Add 10 times (1800 mL) of alcohol to 180 g of the extraction residue of Example 1, heat at 80° C. for 3 hours using a heating mantle with a circulation cooling device, extract, filter, and then concentrate, Drying yielded 11 g of extract.

Abstract

The present invention relates to a method for preparing a Curcuma xanthorrhiza Roxb. extract. The present invention provides a method for preparing a Curcuma xanthorrhiza Roxb. extract comprising: a step of extracting Curcuma xanthorrhiza Roxb. by supercritical extraction to thereby obtain an extract comprising xanthorrhizol as an active ingredient; a step of extracting the residue of the supercritical extraction by alcohol extraction or supercritical extraction to thereby obtain an extract comprising curcumin as an active ingredient; a step of subjecting the residue of the alcohol extractionor supercritical extraction to an enzyme treatment to thereby obtain immunopolysaccharides having an average molecular weight of 33,000 Da; and a step of obtaining an insoluble dietary fiber in the residue of the enzyme treatment, and provides an extract comprising xanthorrhizol, curcumin, immunopolysaccharides, and insoluble dietary fibers obtained by the method described above, and general food,health functional food, cosmetic, and pharmaceutical compositions comprising the extract as an active ingredient. The Curcuma xanthorrhiza Roxb. extraction method according to the present invention allows various kinds of natural extracts to be obtained from one raw material by applying various extraction methods in stages, and thus can be very useful for the preparation of an extract using a natural product.

Description

technical field [0001] The invention relates to a preparation method of turmeric (Curcuma xanthorrhiza Roxb.) extract, in particular to a method for obtaining various functional extracts from turmeric (Curcuma xanthorrhiza Roxb.). Background technique [0002] Turmeric (Curcuma xanthorrhiza Roxb.) is a plant of the Zingiberaceae family. It is a traditional medicinal plant in Indonesia, generally known locally as temulawak or Javanese turmeric. Its main ingredients include fragrant ginger Flavonoids (arturmerone), α-curcumene (α-curcumene), β-curcumene (β-curcumene), curzerenone (curzerenone), geranone (germacrone), β-sesquiphellandrene (β-sesquiphellandrene) ), α-turmerone (α-turmerone), xanthorrhizol (xanthorrhizol) and other terpenoids (terpenoid) compounds and 7 to 30% of essential oils (essential oil), 30 to 40% of carbohydrates (carbohydrate) also There is 0.02 to 2.0% of curcuminoid etc. which are aromatic pigments (Am. J. Chin. Med. 23:243-254, 1995). [0003] Enume...
