Description
Technical field
The present invention relates to a kind of method of from study of semen cassia (Cassia obtusifolia L.), extracting anthraquinone analog compound.Promptly from study of semen cassia, extract Schuttgelb-1-O-β-gentiobioside, chrysophanol-1-O-β-gentiobioside, rheochrysidin-8-O-β-gentiobioside and chrysophanol-1-O-β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-(1 → 6)-β-four kinds of anthraquinone analog compounds of D-glucopyanoside.
Background technology
Semen Cassiae is the dry mature seed of leguminous plants Cassia tora Cassia obtusifolia L. or little Cassia tora Cassia tora L., is clinical conventional Chinese medicine.A large amount of studies show that: the extract of organic solvents such as Semen Cassiae water decoction and ethanol, propyl carbinol, ethyl acetate, Semen Cassiae medicinal extract etc. all has tangible effect for reducing fat.Further research thinks that the main component of Semen Cassiae lipopenicillinase has: anthraquinone class, Semen Cassiae glycosides B, protein etc.But the effective constituent of its lipopenicillinase is still unclear, and Shang Weijian has the lipopenicillinase composition report of particular chemical.
The chemical ingredients of Semen Cassiae mainly contains anthraquinone class, naphthalene a pair of horses going side by side one pyrrones, protein and amino acid, lipid acid, unsaponifiable matter matter, sugar and inorganic elements etc.The anthraquinone class is one of main medicinal ingredients of Semen Cassiae, and its content accounts for about 1.2%.At present oneself from Semen Cassiae isolation identification more than 20 kind of anthraquinone analog compound.Mainly be chrysophanol in the anthraquinone aglycon of Semen Cassiae, content be 2.7 ‰ (Wang Qinghua, the discipline tinkling of pieces of jade, Cong Baozhong, Song Weijing. the content of chrysophanol in the high effective liquid chromatography for measuring Semen Cassiae. the Chinese materia medica journal, 1996,5:48-49).Get chrysophanol, rheochrysidin, Schuttgelb, rhabarberone, aurantio-obtusin, rheochrysidin-8-O-β-6 anthraquinone analog compound (Hao Yanjun of D-glucoside in the therefrom homemade first Cassia tora such as Hao Yanjun, Sang Yuli, Zhao Yuqing. Semen Cassiae anthraquinone class chemical constitution study, herbal medicine, 2003,34:18-19).
The chemical ingredients of Semen Cassiae is very complicated, and separation method commonly used at present mainly contains lixiviation process, extraction process, chromatography etc.Use these methods to be difficult to the chemical ingredients in the Semen Cassiae is separated fully, and be more difficult to get monomeric compound.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of anthraquinone analog compound monomer methods of extracting from study of semen cassia is provided, can obtain Schuttgelb-1-O-β-gentiobioside, chrysophanol-1-O-β-gentiobioside, rheochrysidin-8-O-β-gentiobioside, chrysophanol-1-O-β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-(1 → 6)-β-four kinds of anthraquinone analog compounds of D-glucopyanoside by this method, further development and use in effect for reducing fat have great importance to Semen Cassiae for this.
In order to reach purpose of the present invention, present method adopts the extraction of solvent branch, macroporous resin adsorption and silica gel column chromatography that study of semen cassia is separated, and 4 compounds have been identified by analysis of physical and chemical property and wave spectrum analysis, wherein Schuttgelb-1-O-β-gentiobioside is new anthraquinone analog compound, and chrysophanol-1-O-β-gentiobioside is to separate first to obtain from Semen Cassiae with chrysophanol-1-O-β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyanoside.
Concretely, the inventive method comprises the steps:
(1) study of semen cassia is clayed into power, adopt solvent branch extraction method, according to polarity by little to greatly successively with solvent hexanaphthene, chloroform, ethyl acetate, propyl carbinol, ethanol, water each refluxing extraction 4～6 times in the Soxhlet extraction apparatus, the 1.5-2.5 that each used solvent volume is the herb powder volume doubly, each extraction time is 40-80 minute, and temperature is 60 ± 5 ℃; Merge each extracting solution in step by step, reclaim solvent, obtain aqueous extract;
(2) aqueous extract that step (1) is obtained is dissolved in the distilled water of 5.0-10.0 times of volume, filter and remove insolubles, n-butanol extraction 4-8 time of water-soluble part, the used volume of each extraction is 0.5-1.5 a times of aqueous solution volume, each extraction time is 20-40 minute, and combining extraction liquid volatilizes solvent, the mixture that obtains is isolated and is insoluble to 95% alcoholic acid mixture with 95% dissolve with ethanol of 3.0-8.0 times of volume;
(3) the 95% alcoholic acid mixture that is insoluble to that step (2) is obtained is dissolved in the distilled water of 3-5 times of volume, the impurity of elimination indissoluble, the solution macroporous adsorptive resins of partly flowing through; Being adsorbed on significant part on the post, to adopt 95% ethanol, water to be eluted to successively colourless, collects ethanol eluate, concentrate the ethanol elution thing;
(4) the ethanol elution thing that obtains with 100～200 order silicagel column separating steps (3) adopts chloroform-methanol-water elution system;
(5) chloroform in the elution system of set-up procedure (4): the volume of methyl alcohol=4: 1, the mixture that obtains is through silica gel column chromatography, adopt ethyl acetate: the volume wash-out of 95% ethanol=4: 1.5, the mixture that obtains is further through polyamide column chromatography, methyl alcohol: the volume wash-out of water=2: 3 obtains anthraquinone analog compound II and anthraquinone analog compound III;
Adjust chloroform in the elution system: the volume of methyl alcohol=3: 1, the mixture that obtains is through silicagel column chromatography repeatedly, and adopt ethyl acetate: the volume wash-out of 95% ethanol=3-5: 1.0-2.0 obtains anthraquinone analog compound I;
Adjust chloroform in the elution system: methyl alcohol: the volume of water=3: 1: 0.1, the mixture that obtains is used methyl alcohol through polyamide column chromatography: the mixture that the volume wash-out of water=2: 3 obtains further obtains anthraquinone analog compound IV through gel filtration chromatography, water elution.
(UV NMR) resolves and identifies, confirms described for MS, IR by the general analysis of physical and chemical property in this area and wave spectrum
Anthraquinone analog compound I be Schuttgelb-1-O-β-gentiobioside,
Anthraquinone analog compound II be chrysophanol-1-O-β-gentiobioside,
Anthraquinone analog compound III is rheochrysidin-8-O-β-gentiobioside
Anthraquinone analog compound IV is chrysophanol-1-O-β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyanoside.
In step (1), the used Semen Cassiae of the present invention can be buied from the common Chinese room, clays into power earlier during use, crosses the 100-200 mesh sieve.In all solvents, each extraction time is preferably 55-65 minute, the volume that at every turn extracts solvent with 2.0 times of medicine volume for good.When whenever changing another kind of solvent extraction, residue all must volatilize solvent.
In step (2), the extraction of propyl carbinol is at room temperature carried out, extract at every turn volume with 0.5 times of the sample solution volume for good, the time that at every turn extracts with 25 minutes for good; Preferably fully shook up, place 20 minutes after adding 95% ethanol in the mixture that obtains, precipitation is separated out partly to be and is insoluble to 95% alcoholic acid mixture, called after mixture C.
In step (3): the macroporous adsorbent resin medium refills post after rinsing well with acetone-alcohol-water successively.The used solvent of separation and purification is good with analytical pure, and the consumption of macroporous resin, silica gel, polymeric amide and gel is all decided on the amount of sample.
In four kinds of anthraquinone analog compounds that the present invention obtained, Schuttgelb-1-O-β-gentiobioside is a new compound, and chrysophanol-1-O-β-gentiobioside is to separate first to obtain from Semen Cassiae with chrysophanol-1-O-β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-(1 → 6)-β-D-glucopyanoside.Through identifying that the molecular formula of Schuttgelb-1-O-β-gentiobioside is C
