The extraction, separation and refining of active ingredients of herbal medicines has always been an important part and difficulty in the research of Chinese herbal medicines. Because of the low content of active ingredients of Chinese herbal medicines in Chinese herbal medicines; active ingredients and inactive ingredients coexist; similar structural components interfere with many, traditional extraction and separation The methods often have low extraction rates, are difficult to separate, and even cause pollution.
Supercritical CO2 extraction technology is a high-tech material separation and refining technology with two processes of fractionation and extraction.
It has the characteristics of convenient operation, low energy consumption, no pollution, high separation ability, and no solvent residues. It is widely used in medicine, food, environmental protection and other fields.
Myrrh CO2 oil The myrrh aroma is wonderfully warm, sweet-earthy, smooth, dense, and rich with a soft leather note; the aroma becomes sweeter in the drydown and has excellent fixative properties. It also has a somewhat deeper and richer aroma, and displays a bit more tenacity, than Myrrh essential oil. Yet even in the presence of heavy florals, it imparts… Read More »4 factors affect the CO2 extraction efficiency of myrrh oil
