[0039] Preparation of Coptidis Rhizome Detoxification Nasal Thermosensitive Gel

[0040] Coptidis Rhizoma, Phellodendron Phellodendri, and 70% ethanol were added to reflux extraction twice, and the filtrates were combined and concentrated to 100mL, which was Concentrate A;

[0041] Scutellaria baicalensis, gardenia, decoct three times with water, combine the three filtrates, and concentrate to 100mL, which is concentrated solution B;

[0042] Take an appropriate amount of concentrated solution A and concentrated solution B, add the prescribed amount of excipients P 407, P 188 and PEG 6000 to make it evenly dispersed, store it in a refrigerator at 4-10°C until P 407 is completely dissolved to obtain a clear gel Gel solution, namely Coptidis detoxification thermosensitive gel.

[0043] Determination of Gelation Temperature of Coptidis Rhizome Detoxifying Thermosensitive Gel

[0044] The gelling temperature was determined by the stir bar method. Put 20g of temperature-sensitiv...

Embodiment 1

[0046] 1) 45g Coptidis rhizome, 30g Cortex Phellodendri, add 6 times 70% ethanol to reflux and extract twice, each time for 1.5h, combine the two filtrates, concentrate to 100mL, and obtain concentrated solution A;

[0047] 2) Scutellaria baicalensis 30g, gardenia 45g, add 8 times of water and decoct three times, each time for 0.5h, combine the filtrates three times, concentrate to 100mL, and become concentrated solution B;

[0048]3) Precisely measure 20mL each of the concentrates A and B, add P407, P188 2g, PEG6000 2g, add deionized water to 100g, make it evenly dispersed, store in a refrigerator at 4-10°C until the auxiliary materials are completely dissolved to obtain The clear gel solution is Coptidis Rhizome Detoxifying Nasal Thermosensitive Gel. The amount of P407 was 18g, 20g, 22g, or 24g respectively, and its influence on the gelling temperature was investigated.

[0049] The experimental results showed that when the dosage of P188 and PEG6000 remained constant, the ...

Embodiment 2

[0051] The process is the same as in Example 1, the difference is:

[0052] Precisely measure 20mL each of the concentrates A and B, add 20g of P407, P188, 2g of PEG6000, add deionized water to 100g, make it evenly dispersed, and store it in a refrigerator at 4-10°C until the auxiliary materials are completely dissolved to obtain clarification. Gel solution, namely Coptidis Rhizome Detoxification Nasal Thermosensitive Gel. The amount of P188 was 1g, 2g, 3g, or 4g respectively, and its influence on the gelation temperature was investigated.

[0053] The amount of P188 was positively correlated with the gelation temperature, and T increased with the increase of P188. At a P188 concentration of 2%, the gelation temperature is close to the nasal cavity temperature, see figure 2 .

Abstract

The invention relates to the technical field of traditional Chinese medicines, in particular to rhizoma coptidis antidotal nasal thermo-sensitive gel and a preparation method thereof. The rhizoma coptidis antidotal nasal thermo-sensitive gel is prepared by mixing concentrate of rhizoma coptidis and cortex phellodendri extraction liquid, concentrated liquid of radix scutellariae and fructus gardeniae extraction liquid, poloxamer 407, poloxamer 188, polyethylene glycol 6000 and water. According to the rhizoma coptidis detoxification nasal thermo-sensitive gel, the defects that active componentsare unstable, and can hardly reach a focus are overcome, a preparation technology is simple, the raw materials are easy to get, the medicine efficacy is explicit, irritation is small, and the rhizomacoptidis antidotal nasal thermo-sensitive gel is safe, stable, antibacterial, antiphlogistic and wide in application range.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to a rhizome rhizome detoxification nasal temperature-sensitive gel and a preparation method thereof. Background technique [0002] According to the theory of traditional Chinese medicine, the three medicines of Coptis chinensis, Scutellaria baicalensis and Cortex Phellodendri, referred to as "Sanhuang" for short, are commonly used medicines for clearing away heat, detoxifying and drying dampness in Chinese medicine. Jaundice, dysentery or fever caused by flaming heat and toxin, constipation, sores of the mouth and tongue, etc. are often used in combination with each other to improve the power of clearing away heat and detoxifying. Scutellaria baicalensis is good at clearing the fire of the upper burner, Coptis chinensis is good at clearing the fire of the middle burner, and Huangbai is good at clearing the fire of the lower burnt. [0003] Gardenia, also know...
