摘要:
A method for producing a purified extract of ginseng root which comprises contacting an aqueous extract of ginseng root with a solid absorption resin so as to absorb active saponins contained in the extract on the resin and eluting active saponins from the resin.Also a method of analyzing a ginseng extract which comprises subjecting the extract to silylation to convert saponins contained in the extract to trimethylsilyl ethers, separating the ethers by gas-liquid chromatography and detecting the separated ethers.
摘要:
The present invention relates to compositions comprising Andrographis paniculata extracts combined with Ginkgo biloba extracts complexed with phospholipids.Moreover, the compositions administered in oils rich in ω-3 polyunsaturated fatty acids demonstrate a further synergic effect between the ingredients.Said compositions are useful in the treatment of neurodegenerative disorders, in particular Alzheimer's disease and multiple sclerosis.
