Ginkgo flavonoids have the effects of expanding coronary blood vessels, antispasmodic, and scavenging free radicals in the body. They can be used to treat coronary heart disease and have analgesic and anti-aging effects.

Ginkgolides and white lactones are unique components of Ginkgo biloba and are the natural medicines of choice for the treatment of cardiovascular and cerebrovascular diseases and neurological diseases. Ginkgolide is a very effective platelet-activating factor antagonist and has significant effects on preventing and treating atherosclerosis, hypertension, cerebral ischemia, etc.

Ginkgolide has a unique effect on the treatment of neurological diseases such as Alzheimer’s disease and encephalopathy. In addition, ginkgo phenol and ginkgos, which represent the harmful components of ginkgo Biloba, have anti-cancer effects in addition to pesticides.

Supercritical Carbon Dioxide Extraction of Ginkgo Flavonoids

Since the content of total lactones in the standard extract of Ginkgo biloba leaves is relatively low, the molecular structure of impurities is similar to the medicinal components, and the polarity difference is small, the extraction and separation process of the effective components is more complicated.

Supercritical carbon dioxide extraction is a new separation method.

It has many advantages such as high extraction efficiency, no residual toxicity of solvents, natural active ingredients and heat-sensitive ingredients that are not easy to decompose and destroy, maximum retention of the natural characteristics of the extract, and selective separation. Supercritical fluids are called “super solvents”.

The technology of supercritical carbon dioxide extraction of ginkgo flavonoids uses the characteristics of supercritical fluids.


Top 4 Pros Of the CO2 Extraction Process

Clean And Green

As far as non-polar solvents are concerned, CO2 is among the safest. CO2 is a naturally occurring compound. It exists all around us and our bodies produce it. CO2 extraction systems are by far the cleanest for consumers, producers, and the environment alike.


Supercritical CO2 fluid kills any microbial bacteria, mold, mildew, or insect mites that shouldn’t be in your weed in the first place.


While pricey, supercritical extractors compare well to the cost of other solvent-based approaches when taking into account the safety equipment and special facilities legally required in some countries for working with flammable solvents.

Safest Products

Supercritical CO2 extraction is that there’s no need to use potentially harmful chemicals in the process. Because there are no chemical denaturants or volatile solvents left over in a ScCO2 product, it is undoubtedly the safest extraction process to create a safe product for consumers. The absence of these extra chemicals makes supercritical CO2 concentrates safer to consume and tastier to experience thanks to the preservation of terpene aromas.
