What’s the only living connection between our present world and the age of dinosaurs? The ginkgo biloba plant. Also known as the maidenhair tree, it is regarded as a living fossil and has been around for more than 200 million years. Ancient civilizations in China were already mastering ginkgo processing centuries ago and the tradition soon flourished around the world.

Falling film evaporators concentrate components in gingko processing
A falling film evaporator pumps heating fluid through a heat exchanger, transmitting thermal energy to the ginkgo plant material and vaporizing the solution. The technology concentrates the heat-sensitive components in the extracts.
The concentrate evaporates with the interface of liquid and vapor and prevents the formation of crystals.
Deep eutectic solvents (DES) reduce the ecological impact of extraction
Green chemistry is developing Deep Eutectic Solvents (DES) to reduce the environmental impact of solvent extraction methods.
DES are biodegradable liquids produced by combining hydrogen bond acceptors such as quaternary ammonium salts with hydrogen bond donors. Extraction using DES achieves a high degree of product purity.
Gingko biloba extracts have applications in preventive medicine
The main active ingredients extracted from gingko biloba are ginkgo flavone glycosides and terpene lactones. Clinical formulations typically standardize extracts into EGb 761, containing a 24% concentration of flavonoids and 6% terpenes.
The extract is applied as a protective agent for a range of diseases, from vascular disorders to neurodegenerative conditions.
