Extraction principle of supercritical fluid
Supercritical fluid extraction is mainly divided into two stages: extraction and separation. First, the substances are extracted according to the chemical properties of different substances. After the extraction is completed, the separation of the substances is carried out, and finally the extraction of the required substances is realized.
The application of supercritical fluid extraction technology in the extraction of natural medicines is also completed in this way, and the extraction purity of natural medicines is higher.
Application of Supercritical Fluid Extraction Technology in Natural Medicine Research
Supercritical fluid extraction technology to extract volatile oil from natural medicine
The volatile oil in natural medicine has a great effect and is an important part of natural medicine.
In the volatile oil of natural medicine, the boiling point of the substance is relatively low, and it is easy to oxidize. There will be many problems in the actual extraction process, which will cause a certain degree of damage to the extraction effect.
The application of supercritical fluid extraction technology in the extraction of volatile oil in natural medicines has greatly reduced the time required for extraction, making the extraction work more efficient, and to a certain extent, it has also strengthened the volatile oil in natural medicines. The extraction rate makes the extraction of volatile oil in natural medicines better.
The extraction of flavonoids is of great significance to the study of natural medicine extraction, and has a great influence on the effect of medicines. It can play a good role in the treatment of cardiovascular and cerebrovascular diseases, and can also achieve better therapeutic effects. .
Supercritical fluid extraction technology has also played a very important role in the extraction of flavonoids, and it is also very helpful for the extraction of flavonoids.
Strengthening the research on the application of supercritical fluid extraction technology in the extraction of flavonoids can make the extraction of flavonoids more efficient.
The thermal and polar solvent instability of coumarins is relatively high. The use of supercritical fluid extraction technology for the extraction of coumarins has a very good effect, and it also greatly helps the extraction work. The extraction of vegetables is also easier.
Glycosides also play an important role in natural medicines, and are also a relatively important part of natural medicines. They play a great role in the treatment of hypertension and have a good effect in the treatment of diseases.
In the extraction process of glycosides, a higher temperature is required, which is more conducive to the extraction work, and to a certain extent makes the extraction rate higher.
During the extraction process, ethanol can be added as an additive to achieve better extraction results.
In the traditional extraction process of alkaloids, its pertinence is strong and the extraction range is small. The application of supercritical fluid extraction technology in the extraction of natural medicines has increased the extraction rate of alkaloids, and correspondingly reduced impurities, and improved the purity of alkaloids, making subsequent work better.
Quinone compound extraction
Quinone compounds also play a great role in natural medicine, and there are certain difficulties in the process of extraction.
The amount of quinone compounds is relatively small, and the recovery of some solvents is also more complicated, which has a certain impact on the work.
Supercritical fluid extraction technology has a better extraction effect for quinone compounds in the extraction process of natural medicines.
However, it is important to note that in the extraction process of quinone compounds, the recovery of solvents will have a certain impact on the environment and cause certain damage to the environment.
Supercritical fluid extraction technology has great advantages in the extraction of terpenoids, which improves the extraction rate to a certain extent.
The supercritical fluid extraction technology for the extraction of terpenoids also reduces the cost required for extraction, can achieve better economic benefits, and also makes the extraction work easier.
Extraction of other ingredients
In the process of extracting natural medicines, other medicinal ingredients need to be extracted, and the extraction is carried out according to the actual needs of each substance.
And in the extraction process, we must pay attention to the impact of pressure and temperature on the extraction work, and work according to the different needs of the extract.
With the improvement and development of science and technology, the improvement and optimization of extraction technology in natural medicine will greatly help the work to a large extent.
The development of supercritical fluid extraction technology, to a large extent, promotes better extraction work. While improving the extraction rate of natural medicines, it also improves the purity of the extracts to a great extent, which can make natural medicines better. Play a role.
