已报导,从葛根(Pueraia hirsuta Matsumura)的水提取液中获得氯化胆碱和氯化乙酰胆碱。为了使这些天然成分稳定地保持乙酰胆碱样作用,从葛根的水提取液中除去具有抗胆碱作用的黄豆甙原(Daidzein),黄豆甙(Daidzin)等异黄酮类和鞣质类,制成了具有一定乙酰胆碱样作用的糖浆状提取物,命名为 MTF-101。MTF-101为棕褐色糖浆状物质,在水和甲醇中易溶。将该物质1克溶解在10毫升水中时,水溶液 It has been reported that choline chloride and acetyl chloride are obtained from an aqueous extract of Pueraria hirsuta Matsumura. In order to stably maintain the acetylcholine-like action of these natural ingredients, Daidzein and Daidzin, which have anticholinergic effects, are removed from the aqueous extract of Pueraria root to prepare isoflavones and tannins A certain acetylcholine-like syrupy extract, named MTF-101. MTF-101 is a tan syrup that is soluble in water and methanol. When 1 g of this material was dissolved in 10 ml of water, an aqueous solution was added
