South Korea Regulates The Flavonoid Ratio Of Ginkgo Biloba Extract

Jul 01, 2022

Recently, the Ministry of food and drug safety (MFDS) of South Korea updated the specification changes of two extract raw materials, mainly involving Saw Palmetto Berries Extract and Ginkgo biloba extract.

Ginkgo is known as a "living fossil" in the plant world, with a survival history of 270Million years. Its leaves and fruits can be used as medicine and have a long history of application.

Ginkgo biloba is a rare relic tree species of the Mesozoic era, and it is also a specialty of China. China's Ginkgo resources are mainly distributed in Shandong, Zhejiang, Anhui, Hubei, Jiangsu, Hunan, Sichuan, and other provinces. At present, the output of Ginkgo accounts for 70% of the global market, belonging to a large country of Ginkgo resources.

From the perspective of the plant extract industry, Ginkgo biloba extract is one of the mainstream varieties of raw materials in the extract industry, and its main applications include brain health, antioxidation, visual fatigue, etc. In recent years, Ginkgo biloba extract has always been one of the top 10 export raw materials of extracts in China, and the overall demand in overseas markets is relatively stable.

Adjustment of flavonoids proportion 

The main components of Ginkgo biloba extract are flavonoids, terpene lactones, ginkgolic acid, and other components, of which there are as many as 20 kinds of flavonoids, including quercetin, kaempferol, and isorhamnetin.

In the past, because the proportion standard of quercetin and kaempferol was not clear, many enterprises had corresponding challenges in the production and promotion of this raw material.

Based on this situation, South Korea MFDS has adjusted the proportion of key flavonoids in Ginkgo biloba extract. Specifically, the proportion of quercetin and kaempferol has been changed to 1:0.8~1.2, which will provide a good reference standard for raw material suppliers and end application brands.
