Just as resveratrol in recent years,Ginkgo extract was a star product in the early 90s.However,in a short term,a great mumber of manufacters emerged to supply ginkgo extract without deliberation,both the throughput and production level varied widely.Consequently,the price dropped severely to a few hundred yuan per kilogram now from  4000 US/kg 20 years ago and some orginal enterprises either bankrupted or turned to other industries.In a word,ginkgo extract has become a mass product.

   There are many standards on ginkgo biloba extract,such as CP2002 edition,CP2005 edition and CP2010 edition as well as USP,EB,EGB and so on.Although there are definite restrictions on total ginkgo flavonoids, ginkgolide,ginkgo acid,bilobalide and so on,the ginkgo extract industry is still in disorder.According to herbridge.com,Some of ginkgo extract was adulterated with quercetin and kaempferol whose ratio is around 1.3.

   Some manufacturers in China predominately supply the domestic market,for example, Dapeng natural product Co.Ltd. Some other manufacters mainly supply international market,especially the U.S.market.According to herbridge.com,the price for ginkgo biloba extract without any additives is estimated at 800RMB/kg.

   Jiangsu Pizhou is China’s rural ginkgo where Xuzhou Hengkai Ginkgo Product Co.,Ltd.is located.Although they began to supply ginkgo biloba extract just three or four years ago,their annual output has reached 200 tons.They get ready to enter international market with confidence recently.Dapeng natural product Co.Ltd.has been dedicated to the production of ginkgo biloba extracts since 1993, providing 80-100 tons annually now. Pizhou Fortis Biological Products Co., Ltd.,specialized in ginkgo biloba extract,can supply about 100 tons extracts every year.
