Ginkgo Biloba Extract And Its Health Benefits
Reasons For The Emergence Of Counterfeit Products
Natural products are often considered to be a natural way to correct and improve people’s health systems. Unfortunately, the competitive environment has led to the emergence of counterfeit products in the market.
The active ingredients in Ginkgo Biloba Extract are flavonoid glycosides and terpene lactone, which are present in concentrations of ≥24% and ≥6%, respectively. Current common analytical methods involve a hydrolysis step that converts flavonoid glycosides into aglycones. However, many aglycones are absent in the original ginkgo plant, yet they are used as quality control indicators for Ginkgo biloba products. These inappropriate quality control indicators provide opportunities for adulterating Ginkgo Biloba Extract.
Common Adulteration Methods
Adulteration of Ginkgo Biloba Extracts can occur in various ways, with the most common being the addition of specific plant extracts or the inclusion of certain percentages of flavonoid glycosides and aglycones to meet the requirement of 24% flavonoids. Rutin, quercetin, kaempferol, and isorhamnetin are the most commonly used ingredients. Another type of adulteration involves the use of other parts of the Ginkgo tree, such as roots, bark, or seeds.
Among the aforementioned adulteration methods, the use of other plant extracts rich in flavonoids is the most common. Sophora japonica pods and sophorae flos are rich in rutin and quercetin, but also contain genistein and genistin, which are absent in Ginkgo Biloba Extracts. If Sophora japonica pods or sophorae flos are used to adulterate Ginkgo Biloba Extracts, these compounds will be detected in the analysis.
How to Avoid Inferior Products
1.Test The Sample Using Non-Hydrolysis Detection Method
2.Thin—Layer Chromatography
From the thin layer chromatography, it can be observed that the adulterated Ginkgo Biloba Extract will show obvious characteristic spots of hydrolyzed sophora japonica pods or sophora japonica pods.
