Abstract

The invention discloses a preparation method of dauriciline, which is easy and convenient to operate and has small pollution and low energy consumption. The method comprises the following process steps of: adding fresh menispermum dauricum root stalks into a dilute hydrochloric acid aqueous solution of which the pH is 2-3 for soaking for 24-76 hours; squeezing; filtering; decoloring a filtrate with an active carbon column; collecting a column unloading liquid; concentrating; adding NaOH for adjusting the pH value to 12-13; adsorbing with a macroporous absorption resin column; eluting with ethanol; collecting an eluent; filtering; recovering ethanol under reduced pressure and concentrating; refrigerating; filtering; taking filter residues out; adding ethanol for dissolving; refrigerating; separating precipitates out; and drying and smashing. Due to the adoption of the method for preparing dauriciline, the product purity is high and industrial amplification is easy to realize.

Description

A kind of preparation method of dauriciline
Technical field
The present invention relates to a kind of preparation method of dauriciline, especially a kind of preparation method who from plant, extracts dauriciline.
Background technology
Dauriciline (Dauriciline), molecular formula: C 36H 40N 2O 6, molecular weight: 596.722, CAS accession number: 21446-35-5 mainly is present in fence lichee section, the Menispermaceae various plants.Wherein with the menispermaceous plants yellow parilla Menispermum dauricumDC. content is abundant in the rhizome, and its molecular formula is as follows.
Modern study shows that dauriciline has multiple effects such as anti-inflammatory, antitumor, antimicrobial, anti-HIV, antianaphylaxis, and it is also as the raw material that synthesizes other reactive derivative simultaneously.
The menispermaceous plants yellow parilla Menispermum dauricumDC. dry rhizome is used as the Chinese medicine Rhizoma Menispermi and uses, and is clearing heat and detoxicating, wind-expelling pain-stopping.Be used for swelling and pain in the throat, enteritis and dysentery, rheumatic arthralgia.
In the prior art, still be not applicable to preparation technology's report of high purity dauriciline industrialized production.
Summary of the invention
Technical problem to be solved by this invention provides a kind of preparation method who is beneficial to big production operation, dauriciline that product purity is high.
For solving the problems of the technologies described above, the present invention adopts following technical proposal.
Get fresh yellow parilla rhizome, add the diluted hydrochloric acid aqueous solution that its quality 10-15 doubly measures the pH=2-3 of quality, soaked 24-76 hour, squeezing filters, and filtrate is by the activated carbon column adsorption bleaching, collected post liquid, concentrate, add NaOH and regulate pH value 12-13, adsorb by macroporous adsorptive resins, the 50-70% ethanol elution, collect 3-8 times of column volume elutriant, filter, decompression recycling ethanol also concentrates, refrigeration, filter, get filter residue, add dissolve with ethanol, refrigeration, separate out precipitation, precipitation separation, drying, pulverizing are namely.
Soak quality with diluted hydrochloric acid aqueous solution and be raw materials quality 12 times.
The diluted hydrochloric acid aqueous solution soak time is 42 hours.
Macroporous adsorbent resin is selected from a kind of in D101 type, D102 type, the AB-8 type macroporous adsorbent resin.
The wash-out concentration of ethanol is 60%.
Wash-out is 5 times of amount column volumes with the collecting amount of ethanol.
Preparation gained dauriciline can adopt following method to detect.
Test example 1 HPLC method is measured dauriciline purity.
Chromatographic condition
Chromatographic column: octadecylsilane bonding glue silica gel is weighting agent; Moving phase: the aqueous solution (46: 5: 49) of methyl alcohol-tetrahydrofuran (THF)-1% acetic acid; Flow velocity: 1mL/min; Detect wavelength: 284nm; Column temperature: 35 ℃.
Measuring method
Precision takes by weighing dauriciline 2mg, places the 50mL measuring bottle, adds people's methyl alcohol 20mL, and sonic oscillation makes dissolving, and methanol constant volume is drawn 10 μ L to scale, injects high performance liquid chromatograph, adopts normalization method working sample purity.
Adopt the present invention to prepare dauriciline, be beneficial to big production operation, energy consumption is little, pollutes little.
The present invention is further elaborated below in conjunction with embodiment, but the scope of protection of present invention is not limited to following embodiment.
