Embodiment 1

[0038] Acanthopanax senticosus is crushed into 1 kg of coarse particles of 12-20 mesh, extracted with water, extracted for 1 hour, extracted once, concentrated under reduced pressure, concentrated until the relative density is 1.10-1.15 under the condition of 55°C; the obtained extract (i.e. concentrated The mass fractions of syringin, eleutheroside E and isoxapyridine in liquid) were 0.401%, 0.271% and 0.031%, respectively.

Embodiment 2

[0040] Acanthopanax senticosus is crushed into 1kg of 12-20 mesh coarse particles, extracted with 50% methanol or ethanol, extracted for 1 hour, extracted once, concentrated under reduced pressure, and concentrated until the relative density is 1.10-1.15 at 55°C; the obtained extracted The mass fractions of syringin, eleutheroside E and isoxapyridine in the product (ie concentrated solution) are 0.612%, 0.383% and 0.082%, respectively.

Embodiment 3

[0042] Acanthopanax senticosus is crushed into 1kg of coarse particles of 12-20 mesh, extracted with 75% methanol or ethanol, extracted for 1 hour, extracted once, concentrated under reduced pressure, and concentrated to a relative density of 1.10-1.15 at 55°C; the obtained extracted The mass fractions of syringin, eleutheroside E and isoxapyridine in the product were 0.582%, 0.332% and 0.073%, respectively.

Abstract

The invention discloses a method for preparing eleutheroside. The method comprises the following steps: (1) crushing acanthopanax root into coarse particles of 12-20 meshes, extracting 1-3 times with water or less than 95 percent ethanol, for 1-2 hours each time, combining the extracts, concentrating at reduced pressure until the relative density is 1.10-1.15 at 55 DEG C to obtain a concentrate, and investigating with 3 index components in the acanthopanax root; (2) performing resin column chromatography on the concentrate: washing with water, and eluting with 8-10BV of 30-70 percent ethanol or methanol as eluent, combining the eluents, concentrating at reduced pressure until the eluents are dried, and crushing, wherein the resin column is HP-20, D-101, AB-8 or NKA-9. The product prepared by the method for preparing eleutheroside is high in active component content, high in purity and low in cost.

Description

technical field [0001] The invention relates to a process for extracting traditional Chinese medicine components from Chinese medicinal materials, in particular to a preparation method for extracting the effective components of Acanthopanax senticosus, total glycosides of Acanthopanax senticosus and total glycosides of Acanthopanax senticosus. Background technique [0002] Acanthopanax is the dry root, rhizome or stem of Acanthopanax Araliaceae, which has the functions of dispelling wind-dampness, strengthening muscles and bones, and activating blood vessels; Weakness, bruises, fractures, edema, beriberi, wet itching in the vagina. Pharmacological studies have shown that Acanthopanax has anti-fatigue, anti-cancer and anti-aging effects. The main active ingredients contained in Acanthopanax are syringin, eleutheroside E, and eleutheroside B, which are collectively called eleutherosides, of which syringoside and eleutheroside E are relatively high. as its main medicinal ingr...
