Abstract

The invention discloses a gastrodia elata extract and a preparation method and application thereof, relates to the technical field of food production and application, and solves the technical problemsthat the preparation method of the gastrodia elata extract in the prior art is relatively simple, relatively low in extraction rate and relatively low in content of effective components. The gastrodia elata extract comprises 40% to 50% of gastrodia elata polysaccharide, 1% to 4% of gastrodin, 0.5% to 1.5% of p-hydroxybenzyl alcohol, 0.01% to 0.02% of p-hydroxybenzaldehyde, 0.005% to 0.010% of 3,4-dihydroxybenzaldehyde, 6% to 8% of paricoside A, 1% to 2% of paricoside B and 35% to 45% of paricoside C. According to the gastrodia elata extract and the preparation method thereof, the requirementof fully utilizing gastrodia elata resources can be met. In addition, the gastrodia elata extract is used for preparing a product for improving learning and memory, is safe and free of toxic and sideeffects, and has the effect of remarkably improving the learning and memory functions.
