Embodiment 1

[0039] Step 1, extraction of mercury sulfide sample particles:

[0040] Weigh 2g of Menggenwusu powder, wrap it with filter paper, and put it into a Soxhlet extractor. 150ml of xylene was placed in a round-bottomed flask, heated to reflux at 150°C for 6h, and after natural cooling, a mercury sulfide sample was obtained in the Soxhlet extractor. The mercuric sulfide sample was taken out, placed in a fume hood for 15 hours to volatilize the xylene in the mercuric sulfide sample, then the mercuric sulfide sample was placed in a vacuum oven, and dried at 50° C. for 48 hours to obtain the mercuric sulfide sample particles. Store in a dry box for later use. The free sulfur in the sample is dissolved in xylene, and yellow sulfur crystals can be obtained after the xylene is recovered by distillation under reduced pressure.

[0042] Step 2.1, take 2g of mercuric sulfide sample particles, disperse the m...

Embodiment 2

[0053] Step 1, extraction of mercury sulfide sample particles:

[0054] Weigh 1g of Menggenwusu powder, wrap it with filter paper, and put it into a Soxhlet extractor. 100ml of carbon tetrachloride was placed in a round-bottomed flask, heated to reflux at 100°C for 4h, and after natural cooling, a mercury sulfide sample was obtained in the Soxhlet extractor. Take out the mercury sulfide sample, place it in a fume hood for 10 hours to volatilize the carbon tetrachloride in the mercury sulfide sample, then place the mercury sulfide sample in a vacuum oven, and dry it for 48 hours at 50°C to obtain a mercury sulfide sample Granules are placed in a dry box for later use. The free sulfur in the sample is dissolved in carbon tetrachloride, and yellow sulfur crystals can be obtained after carbon tetrachloride is recovered by distillation under reduced pressure.

[0065] Step 1, extraction of mercury sulfide sample particles:

[0066] Weigh 3g of Menggenwusu powder, wrap it with filter paper, and put it into a Soxhlet extractor. 180ml of benzene was placed in a round bottom flask, heated to reflux at 120°C for 8h, and after natural cooling, a mercury sulfide sample was obtained in the Soxhlet extractor. Take out the mercuric sulfide sample, place it in a fume hood for 18 hours to volatilize the benzene in the mercuric sulfide sample, then place the mercuric sulfide sample in a vacuum oven, and dry it at 50°C for 48 hours to obtain the mercuric sulfide sample particles, put Store in a dry box for later use. The free sulfur in the sample is dissolved in benzene, and yellow sulfur crystals can be obtained after vacuum distillation and recovery of benzene.

Abstract

The invention relates to a method for extracting and separating mercury sulfide nanoparticles in a Mongolian medicine Menggenwusu, belonging to the field of active ingredient extraction of a traditional processed product of a Mongolian medicine. The method comprises extraction of mercury sulfide sample particles and differential separation of mercury sulfide micro-nanoparticles, wherein in the extraction, the mercury sulfide sample particles are extracted by xylene, and elemental sulfur in Menggenwusu is removed; and in the differential separation, the mercury sulfide micro-nanoparticles different in particle size can be obtained by controlling the PVP concentration, feed ratio, centrifuge speed and centrifugation time. By adopting the method provided by the invention, the extracted mercury sulfide micro-nanoparticles have high purity, stable composition and exact structure while clinical administration is more scientific; and moreover, with the separated mercury sulfide micro-nanoparticles different in particle size, the efficacy of the nanoparticles different in particle size can be compared.

Description

technical field [0001] The invention relates to a method for extracting and separating mercury sulfide nanoparticles in Mongolian medicine Menggenwusu, and belongs to the field of extracting effective components of traditional Mongolian medicine processed products. Background technique [0002] Menggenwusu is a commonly used mercury-containing medicinal material in Mongolian medicine, also known as quicksilver. Mongolian pharmacists mix mercury and sulfur at a ratio of 1:1 (hard) or 1:2 (soft) to obtain a blue-gray to gray color after a complex processing process. of lumps. Mercury has a long history of application, pungent, cold, heavy, highly toxic, dry "Xieri Usu", kills insects, eliminates "Qiha", can be used for rheumatoid, travel pain, psoriasis, ringworm, anthrax, Syphilis, and other diseases. [0003] Menggenwusu is the "monarch drug" of the characteristic Mongolian medicine Menggenwusu 18, which has clear curative effects in the treatment of autoimmune diseases, s...
