Embodiment 1
[0046] Example 1 Combined extraction method to prepare the extract of the present invention
[0047] (1) Preparation of extract
[0048] Take 2kg of valerian coarse powder and 2kg of Schisandra chinensis coarse powder, soak them in 4000ml95% ethanol, place overnight, percolate according to the routine, control the percolation speed at 3-5ml / min, add solvent at any time during the percolation process, and percolate until the total valerian The percolate is collected until the assay reaction of the grass element and total lignans is negative, which is the extract. Concentrate to a small volume, dilute with distilled water, pass through a pretreated AB-8 macroporous adsorption resin column, and elute with 6 times the amount of 90% ethanol. Collect the eluate. Resin pretreatment: wash away the fine resin and broken resin with double distilled water first, after wet packing, soak in absolute ethanol 10cm higher than the resin layer for one day, release the immersion liquid, conti...
Embodiment 2
[0059] Valerian root and Schisandra chinensis were mixed at 3:2, crushed into coarse powder, 4000g was taken, and 8 times the amount of 95% ethanol was refluxed and extracted 3 times for 2 hours each time, and the rest were the same as in Example 1 to obtain 153.2g of extract powder. Taking Schisandrin A as an index, the total lignan content was determined by spectrophotometry to be 8.9%, and the valerian content was used as an index to determine the total valerian content by HPLC method to be 28.5%.
Embodiment 3
[0060] Example 3 Combined extraction method to prepare the extract of the present invention
[0061] Valerian and Schisandra were mixed at 2:3, crushed into coarse powder, 4000g was taken, and 8 times the amount of 60% ethanol was refluxed and extracted 3 times, each time for 2 hours, and the rest were the same as in Example 1 to obtain 142.3g of extract powder. Taking schisandrol A as an index, the total lignan content was determined by spectrophotometry to be 14.4%, and the valerian content was used as an index, and the total valerian content was determined by HPLC to be 20.8%.
