Ginkgo biloba, renowned for its medicinal and nutritional value, is a remarkable tree with unique properties. Among its components, polysaccharides have garnered significant attention due to their potential health benefits. The extraction of these polysaccharides from ginkgo fruits has seen notable advancements, particularly with the utilization of supercritical carbon dioxide (CO2) extraction technology.
Polysaccharides are complex carbohydrates found in various natural sources, including plants, and have been recognized for their potential health-promoting properties. In ginkgo fruits, these polysaccharides play a vital role, contributing to their therapeutic and nutritional significance. Ginkgo biloba polysaccharides are known for their antioxidant, anti-inflammatory, and immune-boosting properties.
Three Key Stages Of Supercritical CO2 Extraction Proecss
Supercritical CO2 extraction is an advanced separation and purification technology that utilizes supercritical carbon dioxide as a solvent. In the supercritical state, CO2 combines the properties of both a gas and a liquid, offering unique advantages for extracting bioactive compounds from natural sources. This technology involves three key stages:
In this phase, supercritical CO2 is used to dissolve and extract the target compounds from the ginkgo fruit material.
The extracted compounds are separated from the supercritical CO2 by reducing pressure, allowing the CO2 to revert to a gaseous state.
The final step involves collecting the extracted polysaccharides in a concentrated form.
Top 5 Advantages Of Supercritical CO2 Extraction Proecss
The application of supercritical CO2 technology for polysaccharide extraction offers several significant advantages:
- Selectivity : Supercritical CO2 extraction process can be fine-tuned to selectively target specific compounds, ensuring the purity of the extracted polysaccharides.

Supercritical Co2 Extraction Technology Involves Four Major Steps To Extract Polysaccharides From Ginkgo Fruits
- Pre-Treatment :Ginkgo fruits are typically cleaned and dried to remove impurities and moisture, ensuring a pure extraction.
- Extraction :Supercritical CO2 is introduced into a high-pressure extraction vessel containing the pre-treated ginkgo fruit material. Under controlled temperature and pressure conditions, the CO2 selectively dissolves the polysaccharides.
- Separation :The CO2-polysaccharide mixture is then depressurized, causing the CO2 to revert to a gaseous state and leaving behind a concentrated solution of polysaccharides.
- Collection :The collected solution is further processed to remove any remaining CO2, resulting in a purified form of ginkgo fruit polysaccharides.
Top 4 Applications and Future Prospects
The extracted ginkgo fruit polysaccharides hold immense potential for various applications, including:
- Pharmaceutical Industry : Ginkgo biloba polysaccharides have shown promise in pharmaceutical applications, particularly in the development of drugs with antioxidant and anti-inflammatory properties.
