Ginkgo Biloba

Ginkgo biloba, commonly known as the Maidenhair Tree, is a remarkable and ancient species with no close living relatives, making it one of the most distinctive plants on Earth. It boasts a rich history of cultivation and use in traditional medicine, dating back to early human civilizations. Ginkgo biloba has garnered significant attention in modern herbal medicine due to the unique and diverse compounds it contains. These include terpene trilactones such as ginkgolides, acylated flavonol glycosides known as ginkgoghrelins, biflavones like ginkgetin, as well as ginkgotides and ginkgolic acids.

Typical Active Ingredients

Ginkgolide A

Ginkgolide A is a bioactive compound primarily found in the leaves of the Ginkgo biloba tree. It belongs to a class of diterpenoid lactones known as ginkgolides and is particularly noteworthy for its diverse pharmacological properties. Notably, Ginkgolide A acts as a platelet-activating factor antagonist and has been shown to inhibit the neurotoxicity induced by prions and amyloid-beta (1-42), making it a potential candidate for treating prion diseases and Alzheimer's disease. Additionally, Ginkgolide A exhibits neuroprotective and anxiolytic-like effects, and it is widely utilized in the treatment of cardiovascular diseases and diabetic vascular complications.

Ginkgolide B

Ginkgolide B, a member of the terpene lactone group known as ginkgolides, is particularly notable for its pharmacological effects. This diterpenoid molecule is characterized by a complex structure that includes a unique cage-like arrangement of rings. Ginkgolide B is often identified as one of the primary active components in Ginkgo biloba extracts. The compound has shown potent neuroprotective, anti-arrhythmic, anti-inflammatory, and anti-apoptotic effects. It may serve as a promising agent for inhibiting platelet function and reducing inflammation in conditions such as atherosclerosis.

Molecular structure of ginkgolide B

Bilobalide

Bilobalide is a bioactive compound that belongs to a class of compounds known as terpenoids and is particularly noted for its potential neuroprotective properties. Research suggests that bilobalide may possess various beneficial effects, including antioxidant activity, anti-inflammatory properties, and the ability to protect neurons from damage or death. These qualities make bilobalide a compound of interest in the study of neurodegenerative diseases like Alzheimer's and Parkinson's disease. Beyond its neuroprotective effects, bilobalide has also been studied for its ability to modulate neurotransmitter systems, notably through the inhibition of the gamma-aminobutyric acid (GABA) receptor. This mechanism may contribute to its effects on cognition and mood.

Ginkgetin

Ginkgetin is a naturally occurring bioflavonoid compound primarily found in the leaves of the Ginkgo biloba tree. As a biflavonoid, ginkgetin is structurally characterized by the union of two flavone units. Extensive scientific research has illuminated ginkgetin's diverse pharmacological activities, highlighting its antioxidant, anti-inflammatory, and anticancer properties. Notably, this compound also demonstrates significant neuroprotective benefits and acts as an effective inhibitor of enzymes implicated in the inflammatory response.
