Effect of Ginkgo biloba on Memory.

Ginkgo  also known as the Maidenhair Tree after Adiantum is a unique species of tree with no close living relatives. Extracts of Ginkgo leaves contain flavonoid glycosides and terpenoids (ginkgolides, bilobalides) and have been used pharmaceutically. Ginkgo supplements are usually taken in the range of 40–200 mg per day. Recently, careful clinical trials have shown Ginkgo to be ineffective in treating dementia or preventing the onset of Alzheimer's Disease in normal people.
Recent study about Ginkgo biloba published in Brain Research journal evaluated evaluated the effects of acute (one dose)or subacute treatments (one daily dose/seven days) with EGb 761 (0.5 g kg−1 and 1.0 g kg−1) onrats submitted to a conditioned emotional response (CER) in comparison with positive (4 mg
kg−1 Diazepam) and negative (12%Tween 80) control groups.

I gone through pages of this

I gone through pages of this website and dont know if this is a place to freely discuss over scientific validity of Ginkgo or not? But if I am not wrong, I want to ask if the herbs or medicines that we extract from a plant and tree are STANDARDS or not? I want to know if lets suppose I used a chemical derived from plant A from species1 and some other person derives from plannt B of specoes1 from different location, can it be same? As we all know due to diffrent climatic conditions plant have diffrent characteristics that may appear in the quality of the extract.
