    摘要: The invention provides the novel use of 20(S)-protopanaxadiol in the preparation of medicaments for the treatment of depressive psychiatric disorders. The pharmacological test results indicated that the compound could remarkably increase the level of NE, 5-HT and HAV in the brains of model rats having depressive disorders, remarkably enhance tremors induced by 5-hydroxytryptophan (5-HTP) and behavioral effects induced by levodopa, and inhibit the re-uptake of 5-HT and NA.

    摘要: A synthetic method of 20(s)-ginsenoside Rh2, that is 20(S)-protopanaxdiol-3-O-β-D-glucopyranoside, is comprised of: protecting protopanaxdiol (A1) selectively first to produce monosubstituted protopanaxdiol (A2); and Glycosidating the monosubstituted protopanaxdiol with Glucopyranosyl donor in the presence of Lewis acid catalyst; Deprotecting the product; Then separating and purifying to obtain 20(s)-ginsenoside Rh2. The method is conducted under mild condition at low cost, and affords product with high stereoselectivity, high yield and purity. Therefore, the synthetic method of the present invention is suitable for production on large scale.
