substance, purity reaches 98.5%.Chromatographic column is Alltech Econosphere NH
2Post; Moving phase is acetonitrile-water (volume ratio is 68: 32) solution, flow velocity 5mL/min; Detect wavelength 203nm; 40 ℃ of column temperatures.That this method has is easy and simple to handle, favorable reproducibility, product purity advantages of higher.
Above-mentioned these methods have been discussed the extraction separation of mogroside (glucoside) from different perspectives, and the separation purity that has is higher, and method is simple, but the certain operations complex process is also arranged, can't suitability for industrialized production.And it is not because the polarity of mogroside is big, and easily separated with pigment.Preparation for high-purity momordica glycoside, there is half preparative high-performance liquid chromatographic method to separate at present, though the purity of the momordica glycoside V that this method separation obtains is very high, but used instrument is relatively more expensive and produce composition also than higher, is not suitable for the production of a large amount of purity greater than 90% momordica glycoside V.
Summary of the invention
In order to overcome the deficiency that existing momordica glycoside V purity is low, yield is low or production cost is high, the invention provides a kind of preparation method of high-purity momordica glycoside V, this production method can not only improve momordica glycoside V purity, and can reduce production costs.
The technical solution adopted for the present invention to solve the technical problems is:
(1) earlier Grosvenor Momordica is pulverized, with the alcohol heating reflux extraction 8-18h of 20%-70%, leaching extracting solution, the dregs of a decoction add 30%～60% alcohol heating reflux extraction 4-8h again, and united extraction liquid also is evaporated to paste, obtains A;
(2) A is separated with D101 type macroporous resin column, first deionized water and 20%～30% ethanol are eluted to colourless respectively, again with 30%～50% ethanol elution agent wash-out and collect its elutriant, are evaporated to the medicinal extract shape, must B;
(3) in normal phase silicagel column separated, utilizing chloroform-methanol-water (60: 40: 1～60: 40: 10) was eluent, made collected elutriant ratio be easier to reclaim; Separate at reverse phase silica gel C-18 post, utilizing acetone-water (25: 70～35: 65) is eluent, and used solvent toxicity is lower, uses the acetone of general industrial level to get final product, so production cost is lower.
It is nh 2 column that above-described HPLC detects chromatographic column; Moving phase: EtCN: H2O=75: 25～60: 40; Detect wavelength: 203nm; Flow velocity: 0.6ml/min～1ml/min.
The invention has the beneficial effects as follows: separate obtaining the mogroside standard substance by aforesaid method, can not only improve momordica glycoside V purity, and can reduce production costs, method is simple, good product purity.This provides convenience for studying monomeric activity of mogroside V and drug disposition process, also provides beneficial reference for preparing other Grosvenor Momordica Triterpene Glycosides class standard product.Simultaneously, measure the content of mogroside V in fruit, have great importance for the production of quality, the purchase of instructing Grosvenor Momordica and the mogroside product of determining the Grosvenor Momordica quality.
High-purity momordica glycoside V of the present invention can also be as senior sweeting agent except can be used as standard substance.The high sweet taste substance of contained sugariness is a kind of desirable natural sweeteners of low calory.
