specific Embodiment approach 1

[0010] Specific embodiment one: the preparation method of Kudiezi extract in the present embodiment is carried out according to the following steps:

[0011] Step 1. Take 100kg of Chinese herbal medicines of Kusheria clamosa, and decoct it twice with deionized water. The amount of deionized water used for decocting is 12 to 16 times the mass of the traditional Chinese medicinal materials of A. brusselscens. Each decoction takes 1 hour. The two decoctions are combined and then concentrated to a relative density of 1.12 to 80°C. 1.16 clear ointment;

[0012] Step 2. Add water to the clear paste obtained in Step 1, add water to a volume of 200L, then adjust the pH value to 6.5-7.0 with a 10% sodium hydroxide solution, let it stand for 12-24 hours, and collect the supernatant , the supernatant was adjusted to pH 2-3 with hydrochloric acid solution, then allowed to stand for 12-24 hours, and the upper layer liquid was collected;

[0013] Step 3, pass the upper layer liquid collec...

specific Embodiment approach 2

[0015] Embodiment 2: This embodiment differs from Embodiment 1 in that: the mass concentration of the hydrochloric acid solution in step 2 is 5%. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0016] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the volume concentration of the ethanol solution in Step 3 is 60%-80%. Other steps and parameters are the same as the specific implementation 1 or 2.

Abstract

The invention discloses a preparation method for reserving ixeris sonchifolia hance extractive effective constituent, belonging to ixeris sonchifolia extraction field and aiming at solving the technical problems of the conventional preparation method of the ixeris sonchifolia hance extractive that the process is complex and organic acid is almost drained or damaged by lime cream. The preparation method includes the following stages: first, decocting the ixeris sonchifolia hance through deionized water twice and concentrating into clear paste; second, adding water to the clear paste to adjust the pH value, standing, collecting liquid supernatant, adjusting the pH value to 2-3, standing and then collecting the liquid supernatant; third, passing the liquid supernatant collected in stage 2 through a polyamide resin column, eluting with deionized water, eluting with ethanol solution to get rid of the resin column after pouring out the eluting water, and collecting the ethanol eluent; and fourth, distilling the ethanol eluent under reduced pressure to recover the ethanol, adjusting the pH value to 6.0-7.0, concentrating and drying under reduced pressure. In this way, the ixeris sonchifolia hance extractive can be obtained. Through the preparation method disclosed by the invention, the yield of the extractive can exceed 2.0% and the content of total flavonoids contained in the extractive is over 80%.
