Abstract

The invention discloses a method for separating effective component, atractylenolide II, from Rhizoma Atractylodis Macrocephalae volatile oil. The method includes pulverizing rhizome of dried Rhizoma Atractylodis Macrocephalae, extracting in medium and low polar solvents, and concentrating to obtain tan volatile oil; standing for a certain time, extracting the volatile oil with mixed solution prepared from n-hexane, ethyl acetate, ethanol and water at a certain ratio, collecting upper layer phase, and concentrating to obtain the refined volatile oil; and gradient eluting with mixed solvent of petroleum ether and ethyl acetate at a certain ratio with column chromatography, collecting correspondent fraction, concentrating, and recycling solvent to obtain atractylenolide II. The method performs pretreatment on Rhizoma Atractylodis Macrocephalae volatile oil coarse product by extracting and oxidizing before separating through column chromatography to have simple process and low cost, increased yield and purity of atractylenolide II, and avoids the disadvantages in the conventional post-treatment steps such as crystal loss caused by recrystallization, etc.

Description

A kind of from Rhizoma Atractylodis Macrocephalae volatile oil the method for separating effective ingredient atractylodes lactone II
Technical field
The invention belongs to the Chinese medicine pharmaceutical field, relate in particular to a kind of from Rhizoma Atractylodis Macrocephalae volatile oil the method for separating effective ingredient atractylenolide I.
Background technology
The bighead atractylodes rhizome (Atractylodes macrocephala koidz) is called in art, winter art, Zhejiang art etc., is per nnial herb, is composite family Atractylodes medicinal plant, and its rhizome can be used as medicine, and the beginning is stated from Shennong's Herbal, classifies as top grade.The bighead atractylodes rhizome is warm in nature, and it is sweet, bitter to distinguish the flavor of, and returns spleen, stomach warp, and invigorating the spleen and benefiting QI, eliminating dampness Li Shui, hidroschesis, antiabortive function are arranged.Main product is in Zhejiang, Anhui and other places, with Yinxian County, Zhejiang, area, Xinchang output maximum.Be mainly used in insufficiency of the spleen food less, maldigestion, abdominal distension have loose bowels, lassitude, phlegm and retained fluid are dizzyly throbbed with fear, oedema, spontaneous perspiration, threatened abortion.Modern pharmacological research shows, effect such as the bighead atractylodes rhizome protects the liver, cholagogic, diuresis, antibacterial, anti-inflammatory, antitumor, strengthening immunity, step-down, hypoglycemic, anticoagulation, strong, calmness.
The chemical ingredients of the bighead atractylodes rhizome is mainly Rhizoma Atractylodis Macrocephalae volatile oil, and in the volatile oil content maximum be atractylone, atractylodes lactone class material.Wherein, atractylone has hypotensive activity, atractylenolide, II are effective content of anti inflammation, atractylenolide II) has antitumous effect (Endo K, Toguchi T, Toguchi F, et al.Antiinflammatoryprinciples of Atractylodes.Chem.Pharm.Bull., 1979,27:2954-2958.).This constituents also has to be regulated gastrointestinal function and promotes the function that nutritive substance attracts.
Atractylenolide I (atractylenoide II) belongs to sesquiterpene lactones class chemicals, and molecular formula is C 15H 18O 2, molecular structural formula is:
Figure A20081006079600031
Atractylenolide I is colourless needle, is dissolved in organic solvents such as methyl alcohol, ethanol, ethyl acetate, is insoluble to low polar solvents such as sherwood oil, normal hexane.
Atractylenolide I in the bighead atractylodes rhizome content only 0.07% (Li Wei. the active substance of the bighead atractylodes rhizome and quality approach. Nanjing: Nanjing University of Traditional Chinese Medicine, 2001,38.), and separate relatively difficulty.The normal separation method that adopts of prior art is that high speed adverse current chromatogram separates (Chunxia Zhao, Chaohong He.Preparative isolation and purificationof atractyl on and atractylenolide III from the Chinese medicinal plant Atractylodesmacrocephala by high-speed counter-current chromatography.J.Sep.Sci., 2006,29:1630-1636.) separate with column chromatography chromatogram (Li Wei. the active substance of the bighead atractylodes rhizome and quality approach. Nanjing: Nanjing University of Traditional Chinese Medicine, 2001,29-79.), but the former present stage suitability for industrialized production acquire a certain degree of difficulty, the latter generally need just can obtain purer material after follow-up means such as recrystallization are separated, this is possible loss part material again, moreover, separate the material yield with column chromatography, purity is all lower.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of from Rhizoma Atractylodis Macrocephalae volatile oil the method for separating effective ingredient atractylenolide I.
The objective of the invention is to be achieved through the following technical solutions: a kind of from Rhizoma Atractylodis Macrocephalae volatile oil the method for separating effective ingredient atractylenolide I, exsiccant bighead atractylodes rhizome rhizome is pulverized, powder with in, the solvent leaching of low isopolarity, concentrate, tawny volatile oil crude extract; The volatile oil crude extract of gained is placed for some time, treat its exhaustive oxidation after, with the mixed extractant solvent of normal hexane-ethyl acetate, alcohol and water, get phase by 4: 0~1: 1~4: 1 arbitrary proportion preparation, concentrate, get purified volatile oil; Purified volatile oil separates with the column chromatography chromatogram method, again with petroleum ether-ethyl acetate by 40~150: the mixed solvent of 1 arbitrary proportion preparation carries out gradient elution, collects corresponding flow point; Concentrate, reclaim solvent, get final product colourless acicular crystal atractylenolide I.
Further, described powder concentrates with air distillation or distillation under vacuum with the mixed solvent leaching of petroleum ether-ethyl acetate by 0~40: 1 arbitrary proportion preparation, gets tawny volatile oil crude extract; Described leaching method is that ultrasonic method, cold soaking, heat are carried, diacolation or Soxhlet are extracted.
Further, got mutually after, again with down mutually washing go up phase, concentrate with air distillation or distillation under vacuum, purified volatile oil.
The invention has the beneficial effects as follows: this method before column chromatography earlier to the Rhizoma Atractylodis Macrocephalae volatile oil crude product extract, pre-treatment step such as oxidation, simple to operate, cost is low, and removed the bigger composition of Rhizoma Atractylodis Macrocephalae volatile oil Semi-polarity, improved the wherein content of atractylenolide I, thereby can improve its yield and purity.
