Embodiment 1

[0033] A preparation method of orris root extract, the steps are as follows:

[0034] (1) Get the dry root of Iris, pulverize, cross 40 mesh sieves, and obtain the root powder of Iris;

[0035] (2) Take the orris root powder obtained in step (1), add an aqueous solution containing 60% ethanol that is 40 times the weight of the orris root powder, and simultaneously add 0.05% potassium sodium tartrate of the aqueous solution weight, and stir and extract at 60°C for 0.5h;

[0036] (3) Pressurize the extraction system of step (2) by 100 MPa, and after maintaining the pressure for 2 minutes, restore the ambient pressure instantly, then centrifuge, and get the supernatant;

[0037] (4) adding citric acid to the supernatant obtained in step (3) to adjust the pH value to 5, centrifuging, and getting the precipitate;

[0038] (5) The precipitate obtained in step (4) is dried under reduced pressure to obtain an orris root extract.

Embodiment 2

[0040] A preparation method of an orris root extract, which differs from Example 1 only in that potassium sodium tartrate in Example 1 is replaced by ammonium citrate, and other conditions remain unchanged.

Embodiment 3

[0042] A kind of preparation method of orris root extract, its difference with embodiment 1 is only, potassium sodium tartrate in embodiment 1 is replaced by o-phenanthroline, other conditions remain unchanged.

Abstract

The invention belongs to the technical field of plant extract preparation, and discloses a preparation method, of an iris tectorum root extract. The preparation method comprises: extracting iris tectorum roots by using a solution containing a leaching auxiliary agent, wherein the leaching auxiliary agent can promote leaching of flavonoid compounds in the iris tectorum roots, and the leaching auxiliary agent comprises at least one of sodium potassium tartrate, ammonium citrate, phenanthroline and 8-hydroxyquinoline. According to the method, the sodium potassium tartrate, the ammonium citrate, the phenanthroline or the 8-hydroxyquinoline are added into an extraction solvent, so that the leaching rate of flavonoid components in the iris tectorum roots is effectively increased. According to the preparation method, the yield of effective components in the iris tectorum root extract is effectively increased, the content of total flavonoids is increased, the extraction time is shortened, theextraction cost is reduced, and the prepared iris tectorum root extract has a good antioxidant effect, a good whitening effect and a good collagenase inhibition effect and has a good application prospect in cosmetics.

Description

technical field [0001] The invention belongs to the technical field of preparation of plant extracts, and in particular relates to an orris root extract and its preparation method and application. Background technique [0002] Orris root is the root of the perennial herbaceous plant Iris (scientific name: Iris tectorum Maxim.) of the Iris family Iris. Orris root is rich in flavonoids, mainly isoflavones, which can be used to clear away heat and detoxify, reduce phlegm and sore throat, sore throat, phlegm, cough and asthma. In addition, the flavonoids in orris root will produce aroma components during the cracking process, so that it can be used in burnt sweet products. For the extraction of active ingredients in the root of Orris, the prior art generally adopts a single extraction method, and solvent extraction or supercritical CO 2 extraction. Among them, the yield of active ingredients in the extract obtained by single solvent extraction method is low, and the economy i...
