Embodiment 1

[0058] Example 1: Extraction and purification of Panax notoginseng

[0059] 1. Soak

[0060] Select Lathyrus bean seeds with full grains and no damage, and accurately weigh 500g (m 1 ), first scrub with tap water to remove dust and other impurities on the surface of the seeds; then wash three times with deionized water in the same way, and soak in 1L of deionized water for 6h.

[0061] 2. Pulping

[0062] Weigh the soaked lathyrus seeds and record it as m 2 , then the amount of water absorbed by 500g lathyrus seeds in a 6h time period is m 2 -m 1 . Crush the lathyrus seeds, separate the residue to obtain a slurry, let stand for 3 hours to settle the starch and crude fiber in the slurry, and keep the supernatant for later use. All the separated seed residues can be used as feed or organic fertilizer to make full use of useful resources.

[0063] 3. Coagulation and filtration

[0064] Take 3L of the above supernatant and heat it to near boiling, then add 7.5g CaSO 4 and...

Embodiment 1-2

[0082] Example 1-2: Extraction and purification of Panax notoginseng

[0083] 1. Soak

[0084] Select the full and undamaged pig’s dung bean seeds, and accurately weigh 500g (m 1 ), first scrub with tap water to remove dust and other impurities on the surface of the seeds; then wash three times with deionized water in the same way, and soak in 1L of deionized water for 6h.

[0085] 2. Pulping

[0086] Weigh the soaked pig's dung bean seeds and record it as m 2 , then the amount of water absorbed by 500g of pig's dung bean seeds in a 6h time period is m 2 -m 1 . Grind the seeds of the pig's dung bean, separate the residue to obtain a slurry, let it stand for 3 hours, so that the starch and crude fiber in the slurry can settle, and keep the supernatant for later use. All the separated seed residues can be used as feed or organic fertilizer to make full use of useful resources.

[0098] 2. Pulping

[0099] Weigh the soaked acacia bean seeds and record it as m 2 , then the amount of water absorbed by 500g acacia bean seeds in a 6h time period is m 2 -m 1 . Crush the acacia bean seeds, separate the residue to obtain a slurry, let stand for 3 hours, so that the starch and crude fiber in the slurry settle, and keep the supernatant for later use. All the separated seed residues can be used as feed or organic fertilizer to make full use of useful resources.

Abstract

The invention belongs to a process or method for purifying active ingredients in the field of medicines, and particularly relates to a pretreatment method for extracting dencichine from plants. The pretreatment method does not involve an organic solvent, so that the obtained product has no toxic or side effect and is safe to use. And on the other hand, dencichine is used as a hemostatic component, so that the hemostatic effect of toothpaste, band-aid or hemostatic bandage can be better promoted. For example, the mass ratio of the crude dencichine extract in the toothpaste is 0.01%-4.0%.

Description

technical field [0001] The invention belongs to a process or method for purifying active ingredients in the field of medicine, in particular to a pretreatment process for extracting notoginseng with medicinal value from plants containing notoginseng. Background technique [0002] Panax notoginseng is a water-soluble component of panax notoginseng, a special amino acid isolated from the root of panax notoginseng, which can shorten the coagulation time and significantly increase the number of platelets. It was further confirmed that notoginseng has a better hemostatic effect than tranexamic acid. [0003] CN102379827B discloses a toothpaste containing notoginseng. Specifically, the toothpaste is prepared by adding notoginsenoside and notoginseng into the toothpaste base, and the weight percentages of notoginsenoside and notoginseng are 0.2-1.2% and 0.01-1.0%; the prepared toothpaste can kill Pyogenic coccus, Candida albicans, Staphylococcus aureus, anaerobic bacteria and oth...
