Embodiment 1

[0018] 1. Raw material pretreatment: remove sundries and mildew from fresh Huaxiangshu infructome raw materials, then dry them, and use a plant grinder to grind them to obtain Huaxiang fruit materials for later use; the diameter of the sieve hole of the grinder is 2 mm;

[0019] 2. Put 100 g of purified, air-dried and crushed Huaxiangguo material and 2000 mL of extraction water into a beaker, heat in a water bath, control the temperature at 80°C, extract for 60 min, extract twice, and filter to remove residue , combined the filtrates to obtain 3840 mL of crude extract;

[0020] 3. The extract was concentrated in vacuum at a vacuum degree of -0.095MPa and a temperature of 55°C, and then vacuum freeze-dried to obtain 32.7 g of Huaxiangguo crude extract.

Embodiment 2

[0022] 1. Put 150 g of Huaxiang fruit pretreated according to the method of Example 1 and 2250 mL of extraction water into a water bath for extraction. The temperature was controlled at 70°C, and the extraction time was 30 min. Extracted 2 times, filtered to remove slag, combined filtrate to obtain 4230 mL of extract;

[0023] 2. Concentrate the extract, cool to room temperature, put it in a refrigerator at 5°C for 24 hours, and then separate out 1250 mL of the clear liquid;

[0024] 3. Add the supernatant to the pretreated D101 macroporous adsorption resin separation column at a flow rate of 1.7 BV / h, then wash the column with 2.0 BV / h of pure water, and then use 70% ethanol aqueous solution at 2.2 BV The eluent is eluted at a flow rate of / h to obtain the eluent; the eluent is distilled at normal pressure to steam ethanol to obtain the extract purification solution;

[0025] 4. Concentrate the purified extract solution in vacuum at a vacuum degree of -0.1MPa and a heating ...

Abstract

The invention relates to platycarya fruit extract with an anti-oxidization function and a preparation method of platycarya fruit extract. The preparation method of the platycarya fruit extract comprises the following steps of: by adopting naturally dried platycarya fruit as the material, crushing the material and adding pure water for purifying to obtain coarse extract; settling and separating the coarse extract under a low temperature, and adsorbing and separating the clear liquor by macroporous resin to obtain purified liquor; and respectively carrying out the steps including concentrating and drying on the coarse extract liquor and the purified liquor to obtain the anti-oxidization platycarya fruit extract with different polyphenol contents to satisfy different requirements. The platycarya fruit extract which is prepared by the preparation method disclosed by the invention has good water solubility and extremely good anti-oxidization activity; moreover, the preparation method is simple and easy to implement, and easily realizes industrialization, so that a foundation is laid up for developing and utilizing the platycarya fruit.

Description

technical field [0001] The invention relates to the extraction of plant active substances, in particular to an extract of natural antioxidant active substance Huaxiangguo extracted from Huaxiangguo and a preparation method thereof. Background technique [0002] Huaxiang fruit is the Juglandaceae plant Huaxiang tree ( Platycarya strobilacea Sieb. et Zucc.), Huaxiang trees are widely distributed in East China, Central China, South China, Southwest China and other regions. Huaxiang fruit is pungent in taste and warm in nature. It has the miraculous effects of clearing heat and detoxifying, promoting blood circulation and removing blood stasis, clearing swelling and discharging pus, opening orifices and relieving pain. Its decoction is used by folks to treat rhinitis and sinusitis, and the effect is very good. The compound preparation of Xiangguo as the main medicine is used to treat acute and chronic sinusitis and rhinitis, and has achieved good curative effect. [0003] It ...
