Problems solved by technology

[0003] However, the current traditional Chinese medicines for the treatment of lung yin deficiency type dry eye syndrome are usually made into pills or decoctions for oral administration. It is painful, and the diameter of the pills is small and easy to lose, resulting in waste, and the packaging cost is relatively high. The decoction made of it has an unpleasant smell and a bitter taste. It also has difficulty in taking medicine, and unnecessary waste caused by pouring the decoction. , Oral administration starts from the inside, for dry eye syndrome, the effect of the medicine is slow

Embodiment 1

[0039] Prescription: 12 parts of raw land, 10 parts of Ophiopogon japonicus, 15 parts of Scrophulariaceae, 9 parts of white peony, 9 parts of paeonol, 6 parts of mulberry leaves and 16 parts of chrysanthemum.

[0040] Take the above-mentioned medicinal materials, crush them to 20-40 meshes respectively, then weigh them according to the above-mentioned amount, and mix them evenly in the extraction kettle. Carbon dioxide was used as the medium for supercritical fluid extraction for 3 hours, and the first extract was obtained from the separation tank.

[0041] Then adjust the pressure of the extraction kettle to 35MPa, the temperature to 45°C, the pressure to the separation kettle to 6MPa, and the temperature to 20°C, and use 20% ethanol as the medium to carry out supercritical fluid extraction for 2 hours to obtain the extract I; Kettle pressure 6MPa, temperature 30°C, use 60% ethanol as the medium to carry out supercritical fluid extraction for 3 hours to obtain extract II; the...

Abstract

The invention discloses fumigation liquid for lung-yin deficiency type xerophthalmia and preparation thereof, and belongs to the technical field of traditional Chinese medicine extraction. The fumigation liquid for the lung-yin deficiency type xerophthalmia comprises 1-50 parts of radix rehmanniae, 1-50 parts of radix ophiopogonis, 1-50 parts of radix scrophulariae, 1-50 parts of radix paeoniae alba, 1-50 parts of cortex moutan, 1-50 parts of folium mori and 1-50 parts of chrysanthemum. The scheme has the following advantages that the fumigation liquid mainly aims at the treatment of the lung-yin deficiency type xerophthalmia, the pain caused by oral administration is effectively avoided, and the extracted liquid can be changed into steam through a fumigation instrument to be in direct contact with eyes, so that the treatment effect is stronger, meanwhile, the oxidation and dissipation of heat-sensitive substances are effectively prevented, and the effective components of the traditional Chinese medicinal materials are well kept in an extract; and toxic and harmful organic solvents are not used in the whole process, ethanol with different concentrations is only used as a modifier,and the extract does not have residual toxic and harmful solvent substances, so that the existence of harmful substances to human bodies and the pollution to the environment in the extraction processare prevented, and 100% pure natural property is ensured.

Description

technical field [0001] The invention relates to the technical field of extracting traditional Chinese medicines, in particular to a fumigation liquid for dry eye syndrome of lung yin deficiency and its preparation. Background technique [0002] Traditional Chinese medicine is my country's traditional medicine, which is valued by countries all over the world based on its rich resources and unique curative effect. At the same time, compared with traditional Chinese medicine, chemicals have stronger toxic and side effects. Therefore, the efficient extraction of active ingredients in traditional Chinese medicine is very important. Traditional methods for extracting active ingredients of traditional Chinese medicine mainly include: maceration method, pre-cooking method, reflux extraction method, steam distillation method, vacuum distillation method, sublimation method, etc. These methods have disadvantages such as complex extraction process, low product purity, organic residues,...
