The extraction process of Herba Cistanches medicinal material effective ingredient
One, technical field
The present invention relates to the method for extraction, separating effective ingredient from Chinese medicinal materials, particularly the method for high efficiency extraction D-N.F,USP MANNITOL, phenylethyl alcohol glycoside, polysaccharide from the Herba Cistanches medicinal material belongs to Chinese medicinal ingredients extractive technique field.
Two, technical background
Herba Cistanches (Cistanche salsa G.Beck) has another name called that sacsaoul rues greatly, smart bamboo shoot, essence, be China's rare Chinese medicine, pharmacopeia is included, and mainly is grown in desert regions such as China's West Inner Mongolia, Gansu, Xinjiang.Herba Cistanches beginning is stated from Shennong's Herbal, classifies as top gradely, has kidney invigorating and YANG supporting, benefiting essence and marrow, enriching blood and moistening for dryness, pleases look effect such as prolong life, and cures mainly under impotence in male, infertilitas feminis, the band, cards such as metrorrhagia, waist knee crymodynia, blood depletion constipation.
Contain biological effect compositions such as phenylethyl alcohol glycoside, D-N.F,USP MANNITOL, polysaccharide, trimethyl-glycine in the Herba Cistanches medicinal material.The extracting method of Herba Cistanches biological effect composition is a lot, but most extracting method only is confined in a kind of extraction of biological effect composition, has ignored the extraction of other biological functional component, causes the significant wastage of resource.
Three, summary of the invention
Technical problem
The object of the present invention is to provide a kind of extraction process of Herba Cistanches medicinal material effective ingredient, the processing method of high efficiency extraction phenylethyl alcohol glycoside, D-N.F,USP MANNITOL, polysaccharide from the Herba Cistanches medicinal material has simultaneously remedied the undue extraction of paying attention to single component in the traditional extraction process and the shortcoming of loss Other Meat desert cistanche biological effect composition.
Technical scheme
The extraction process of Herba Cistanches medicinal material effective ingredient, its step is as follows:
(1) with the Herba Cistanches medicinal material through 60 ℃ of oven dry, be ground into 40 orders;
(2) Herba Cistanches D-N.F,USP MANNITOL extracts: get the Herba Cistanches powder, adopting volume ratio content is the ethanolic soln extraction of 90-95%, the consumption that extracts solvent is 5-10 a times of Herba Cistanches weight, extraction time is 2-3 time, extracting method is the refluxing extraction method, and extracting solution is through concentrated, crystallization, the dry Herba Cistanches D-N.F,USP MANNITOL that gets.
(3) phenylethyl alcohol glycoside extracting method: with the extraction residue that obtains in the step 2, with volume by volume concentration is that the ethanolic soln of 60-80% extracts, the consumption that extracts solvent is 8-10 a times of Herba Cistanches weight, extraction time is 2-3 time, extracting method is the microwave auxiliary reflux extracting method, extracting solution is collected elutriant by macroporous resin, through concentrated, the dry Herba Cistanches phenylethyl alcohol glycoside that gets;
(4) extracting method of Herba Cistanches polysaccharide: go into the distilled water heating in the extraction residue that will from step 3, obtain and extract, the consumption that extracts solvent is 10-15 a times of Herba Cistanches weight, extraction time is 2-3 time, extracting method decocts extracting method for heating, after extract finishing, supernatant liquor adds 95% ethanol sedimentation of 3 times of volumes behind concentrating under reduced pressure, leaves standstill 24 hours under 4 ℃, centrifugal back collecting precipitation, drying can obtain the Herba Cistanches polysaccharide;
Herba Cistanches medicinal material in the extraction process of above-mentioned Herba Cistanches medicinal material effective constituent in the step (1) is a Saline Cistanche Herb Cistanche salsa G.Beck chylocaulous.Drying means in step (2), (3), (4) is reduced vacuum drying, spraying drying or lyophilize.
Beneficial effect
Extracting method of the present invention is compared with traditional extraction process, has the following advantages:
1. the extracting method among the present invention is compared with traditional extraction process, can obtain Herba Cistanches N.F,USP MANNITOL, cistanche glycosides, three kinds of Herba Cistanches biological effects of Herba Cistanches polysaccharide composition simultaneously, utilize the Herba Cistanches raw material to greatest extent, remedied the undue extraction of paying attention to single component in the traditional extraction process and the shortcoming of loss Other Meat desert cistanche biological effect composition.
2. the ethanol that uses among the present invention can reclaim in the concentrating under reduced pressure process, continues to use in the leaching process, reaches the effect of recycle, thereby has effectively reduced production cost.

Five, embodiment:
Embodiment 1:
Herba Cistanches powder 1kg, adding 10 times of amount concentration is the ethanol of 90% (V/V), extracts 2 hours, with 8 times of amount 90% (V/V) extraction using alcohols, merges extracted twice liquid again, through concentrating under reduced pressure, crystallization, the dry crystalline material 16g that gets, the D-mannitol content is 50%.Extract residue, continuing with concentration is that 80% (V/V) ethanolic soln extracts 2 times, and extracting solution gets Herba Cistanches alcohol extract 300g through concentrating under reduced pressure, spraying drying, contains phenylethyl alcohol glycoside 5%.To extract the distilled water that continues to add 10 times of amounts in the residue, heating extracts twice, and supernatant liquor adds 95% ethanol sedimentation of 3 times of volumes behind concentrating under reduced pressure, left standstill under 4 ℃ 24 hours, centrifugal back collecting precipitation, drying can obtain Herba Cistanches polysaccharide 60g, and purity is 75%.
