Embodiment 1
[0017] The first step: the galls produced by the larvae of the Gallaceae insect Gallaceae parasitizing on the twigs of the Fagaceae Quercus infectoria Oliv. are selected as the Gallaceae medicinal material;
[0018] Step 2: Grind the gallic medicinal material, pass through a 30-mesh sieve, use water as a solvent, and reflux extract the crushed gall for 3 times for 2 hours each time, and combine the extracts;
[0019] The third step: the combined extract obtained in the second step is subjected to column chromatography on a polyamide resin or a macroporous adsorption resin in an exchange device, firstly eluted with pure water and then with a 30% ethanol aqueous solution gradient, and analyzed by liquid mass spectrometry The fractions containing mass-to-charge ratios of 321±1 and 635±1 were measured and collected, and the effective fractions of gallic tannins were obtained after drying. The contents of gallic acid and total tannins were 83% based on dry product weight. The effec...
Embodiment 2
[0021] The first step: the galls produced by the larvae of the Gallaceae insect Gallaceae parasitizing on the twigs of the Fagaceae Quercus infectoria Oliv. are selected as the Gallaceae medicinal material;
[0022] The second step: crush the medicinal material of gall, pass through a 40-mesh sieve, use 50% ethanol water as a solvent, and reflux extract the crushed gall twice for 3 hours each time, and combine the extracts;
[0023] The third step: the combined extract obtained in the second step is subjected to column chromatography on a polyamide resin or a macroporous adsorption resin in an exchange device, firstly eluted with pure water and then with a gradient of 25% methanol aqueous solution, and analyzed by liquid chromatography-mass spectrometry The fractions containing mass-to-charge ratios of 321±1 and 635±1 were measured and collected, and the effective fractions of gallic tannins were obtained after drying. The contents of gallic acid and total tannins were 85% base...
Embodiment 3
[0025] The first step: the galls produced by the larvae of the Gallaceae insect Gallaceae parasitizing on the twigs of the Fagaceae Quercus infectoria Oliv. are selected as the Gallaceae medicinal material;
[0026] The second step: pulverize the gallic medicinal material, pass through a 30-mesh sieve, use ethyl acetate as a solvent, and reflux extract the pulverized gallic twice for 3 hours each time, and combine the extracts;
[0027] The third step: the combined extract obtained in the second step is subjected to column chromatography on a polyamide resin or a macroporous adsorption resin in an exchange device, and firstly eluted with pure water and then with a 25% ethanol aqueous solution gradient, and liquid chromatography-mass spectrometry The fractions containing mass-to-charge ratios of 321±1 and 635±1 were measured and collected, and the effective parts of gallic tannins were obtained after drying. The contents of gallic acid and total tannins were 81% based on dry pro...
