Abstract:

Ginkgo biloba is an important traditional economic forest and greening tree species in China. The productive value of G. biloba industry chain is 20 billion yuan, which is an important local agriculture and forestry industry. China's ginkgo resources account for 85% of the world, with ginkgo planting area of about 400 000 hm² and the number of cultivation of more than 2.5 billion. This paper summarized the ginkgo resources, distribution and main use parts, introduced main ginkgo products (Ginkgo biloba leaves extract, ginkgo preparations and gingko seed) and the present situation of processing technology, product quality control and its analysis method, analyzed the trend of the development of industry. There is a clear gap between the processing technology of Ginkgo biloba leaves in China and the international advanced level. There are generally problems such as small scale, backward equipment, weak technical force, low production efficiency, poor product quality and product standard not up to international standards, and lack of high, fine and sharp deep processing ginkgo products. The future ginkgo industry needs to focus on the development of high-value-added products, high-end cosmetics and biological feed field. At the same time, aiming at the new form of revitalizing the mountain village and the characteristic small town, this paper puts forward the ideas of G. biloba industry in developing the characteristic Ginkgo cultural industry, G. biloba leisure sightseeing and G. biloba characteristic rural health care industry.
