Name of Marker Compounds and Their Chemical Nature:
1. Flavonoid Glycosides:
Such as quercetin, kaempferol, and isorhamnetin.
These compounds are antioxidants and contribute to the majority of ginkgo's free radical-scavenging activity.
2. Terpene Lactones:
Including ginkgolides and bilobalide, which are unique to ginkgo.
These compounds are thought to improve blood flow and protect nerves
Medicinal Uses and Health Benefits:
1. Cognitive Function and Dementia:
Ginkgo biloba is widely used to improve cognitive function, memory, and to possibly slow down cognitive decline in conditions such as Alzheimer's disease.
Studies have shown mixed results, with some suggesting slight improvements in cognition and others showing no significant effect.
2. Circulatory Health:
Ginkgo's ability to improve blood flow, including to the brain, makes it a popular supplement for circulatory problems.
It's been used to treat conditions like claudication (pain caused by too little blood flow during exercise) and Raynaud's phenomenon.
3. Antioxidant and Anti-inflammatory:
Ginkgo's flavonoid content provides significant antioxidant benefits, which can help reduce the damage from free radicals and inflammation.
4. Eye Health:
The antioxidants in ginkgo may help protect the eyes from damage caused by free radicals, which is linked to age-related macular degeneration and glaucoma.
