Title (EN) METHOD FOR EXTRACTING AND SEPARATING GINKGOLIDES
(FR) PROCÉDÉ D'EXTRACTION ET DE SÉPARATION DE GINKGOLIDES
(ZH) 一种银杏内酯的提取分离方法
Abstract:
(EN) A method for extracting and separating ginkgolides. The ginkgolides obtained through steps of extraction on a ginkgo leaf, further extraction, column chromatography, crystallization, and crystal mixing comprise 25.0% to 50.0% of bilobalide (C15H18O8), 20.0% to 45.0% of ginkgolide A (C20H24O9), 10.0% to 30.0% of ginkgolide B (C20H24O10), and 5.0% to 15.0% of ginkgolide C (C20H24O11). The total quantity of the bilobalide, the ginkgolide A, the ginkgolide B, and the ginkgolide C is over 95%.
(FR) L'invention concerne un procédé d'extraction et de séparation de ginkgolides. Les ginkgolides obtenus par les étapes d'extraction sur une feuille de ginkgo, nouvelle extraction, chromatographie sur colonne, cristallisation et mélange de cristaux comprennent de 25,0 % à 50,0 % de bilobalide (C15H18O8), de 20,0 % à 45,0 % de ginkgolide A (C20H24O9), de 10,0 % à 30,0 % de ginkgolide B (C20H24O10) et de 5,0 % à 15,0 % de ginkgolide C (C20H24O11). La quantité totale du bilobalide, du gingkolide A, du gingkolide B et du ginkgolide C est supérieure à 95 %.
