Embodiment 1

[0020] Take southern Schisandra fruit powder as raw material, weigh 20g and put it into supercritical CO 2 Extraction unit, in CO 2 Static extraction for 5 hours at a pressure of 25MPa and an extraction temperature of 35°C; then at an extraction pressure of 25MPa, an extraction temperature of 35°C, 2 Under the condition of flow rate 2L / min, dynamic extraction was carried out for 3 hours, and the separation temperature was 60°C, and the extract and raffinate residue of Schisandra chinensis were collected. Schisandra chinensis was used as reference substance, chromotropic acid was used for color development, and the lignan content was determined by spectrophotometry. The result was that the total lignan extraction rate in the southern Schisandra extract was 95.5%, and the lignan content was 9.2%.

[0021] Southern Schisandra supercritical CO 2 The residue of the raffinate is used as the raw material, the ratio of material to liquid is 1:20 (w / v, g / mL), the boiling water is ref...

Embodiment 2

[0023] With Schisandra chinensis fruit powder as raw material, operate in the same way as in Example 1. Using Schisandra A as the reference substance, chromotropic acid was used for color development, and the lignan content was determined by spectrophotometry. The result was that the total lignan extraction rate in the Schisandra chinensis extract was 93.2%, and the lignan content was 13.0%. Schisandra supercritical CO 2 The crude polysaccharide yield in the raffinate residue was 19.6%, and the polysaccharide content measured by the phenol-sulfuric acid method was 28.5%.

Embodiment 3

[0025] Using southern Schisandra fruit powder as raw material, solid-liquid ratio 1:10 (w / v, g / mL), reflux of 60% ethanol solution (v / v) to extract lignans in Schisandra chinensis, extract twice, each time for 2 hours . Filtrate, concentrate the filtrate in vacuo to obtain the extract extract, and collect the alcohol extraction residue. Taking Schisandra A as reference substance, chromotropic acid was used to develop color, and the content of lignans was determined by spectrophotometry. The result was that the extraction rate of total lignans in the extract of Schisandra chinensis was 70.8%, and the content of lignans was 3.6%.

[0026] The residue after extracting lignans from Schisandra chinensis with 60% ethanol is used as raw material, the ratio of solid to liquid is 1:20 (w / v, g / mL), the boiling water is extracted in the same flow for 6 hours, extracted once, filtered, and the filtrate is concentrated under reduced pressure To 1 / 3 of the original volume, the concentrated...

Abstract

The present invention belongs to the field of schisandra processing technology, and is especially comprehensive schisandra utilizing process. The process capable of utilizing two kinds of active schisandra components, lignan and polysaccharide, includes the following steps: the first supercritical CO2 fluid extraction or alcohol extraction to extract the schisandra lignan from schisandra fruit powder as the material, and the subsequent hot water extraction of schisandra polysaccharide from the residue after lignan extraction. The lignan extract and the polysaccharide extract may be used as food and medicine. The present invention raises the comprehensive utilization value of schisandra obviously.

Description

technical field [0001] The invention relates to the technical field of schisandra processing, in particular to a method for comprehensively utilizing schisandra, which can simultaneously utilize two active components of lignan and polysaccharide in schisandra. Background technique [0002] Schisandra chinensis (Schisandra chinensis (Turcz.) Baill, commonly known as Northern Schisandra) or Huazhong Schisandra (S.sphenanthera Rehd. It tastes sour, sweet, and warm in nature. It belongs to the lungs, heart, and kidneys. , Schisandra lignans are the main active ingredient in the hepatoprotective effect of Schisandra chinensis, and Schisandra polysaccharides have various functions such as anti-tumor and anti-aging. But at present, the utilization of Schisandra chinensis is mainly lignans, and the utilization of active ingredients such as polysaccharides is less; Schisandra chinensis residue after extraction of lignans is generally discarded as waste, resulting in a waste of medic...
