specific Embodiment approach 1

[0026] Specific embodiment one: the method of this embodiment is realized through the following steps: take 1 kg of Xanthos radix radix kernels and dry them, press the dried Xeroxes radix radix kernels with an oil press to obtain cake powder, add the weight of cake powder to the cake powder 2 to 3 times of n-hexane extraction 3 to 5 times, 4 to 6 hours each time, the extract was decompressed to recover n-hexane, dried to become xanthophyll fruit kernel cream, take 900 ~ 1100g of xanthophyll fruit kernel cream, and pour it to Add 4-8 liters of alcohol solution with a concentration of 55-85% to the fruit kernel cream, heat to reflux or ultrasonically extract for 2-4 hours, extract again in the same way, filter the extracts, combine them, and depressurize at a low temperature of 60°C-70°C Recover the alcohol until there is no alcohol smell, add 1-2 liters of water to dissolve, filter, add 1-2 liters of n-butanol to the filtrate to extract, extract again in the same way, filter the...

specific Embodiment approach 2

[0027] Specific embodiment 2: In this embodiment, the resin column is filled with yin and yang resin, D201, AB8, HP20, HP825 or D101 adsorption resin, the filling height is 30-100 cm, and the alcohol is washed with water for later use. Other methods are the same as in the first embodiment.

specific Embodiment approach 3

[0028] Embodiment 3: In this embodiment, the inner diameter of the resin column is 3-8 cm. Other methods and specific

[0029] Embodiment 1 or 2 are the same.

Abstract

Disclosed is a method for extracting effective site of Xanthoceras sorbifolia hulled seed which comprises the following steps: charging n-butanol into filtrate for extraction, filtering the extract, merging and reclaiming ethanol till no alcohol smell is present, charging water for dissolving, filtering, injecting the dissolved matter to treated resin columns, adsorbing for 20-40 minutes, washing with water and alcoholic solutions.

Description

technical field [0001] The invention relates to a method for extracting effective parts of traditional Chinese medicine. Background technique [0002] Among Xingguan fruit kernels, substances used to treat frequent urination, urinary incontinence, mental retardation in children, brain aging, middle-aged and elderly dementia, and Parkinson's syndrome, which can improve brain function and brain activity, have been identified as total saponins of Xingguan fruit. Extracting the total saponins of X. radix sorbifolium from kernels of X. sorbifolium is quite difficult. In the prior art, the content of the total saponins of X. sorbifolium can only reach 30% of the total substance in the effective part extracted from the kernels of X. sorbifolium. This involves the use of accurate pure compound indicators to directly measure the accuracy of the total saponins content of X. xantha. More than 50% of the total substances can be called total saponins. However, the current method for ca...
