Embodiment 1

[0033] Example 1 Preparation of total phenolic acid extract of hydrangea flower leaves (1)

[0034] The dried medicinal materials of 2kg of pulverized hydrangea leaves were added in 60% ethanol for 12 hours in a ratio of 1:5 by weight of the medicinal materials: ethanol solution, and then heated and refluxed for 3 times, each extraction time was 2h, 2h, 2h. Combine the three extracts, filter, recover the solvent, and concentrate to a relative density of 1.00-1.20. The concentrated liquid was extracted three times with petroleum ether and n-butanol respectively, and extracted according to the ratio of concentrated liquid: solvent weight ratio of 1:1. The three n-butanol extracts were combined and concentrated to obtain 67.8 g of the n-butanol extract. The n-butanol extract was dissolved in 1.5L of distilled water, filtered, and the filtrate was adsorbed on a 2kg AB-8 type macroporous resin column, and the adsorption was repeated three times. First, use 3 times the column volume...

Embodiment 2

[0035] Example 2 Preparation of total phenolic acid extract of hydrangea flower leaves (2)

[0036] 2kg of the dried medicinal materials of the pulverized hydrangea leaves were added with 70% ethanol at a weight ratio of 1:10, soaked in 70% ethanol for 12 hours, and then heated and refluxed for 3 times, each extraction time was 2h, 2h , 2h. Combine the three extracts, filter, recover the solvent, and concentrate to a relative density of 1.00-1.20. The concentrated liquid was extracted three times with petroleum ether and n-butanol respectively, and the concentrated liquid: solvent weight ratio was 1:1. The three n-butanol extracts were combined and concentrated to obtain 85.3 g of the n-butanol extract. The n-butanol extract was dissolved in 2.8L of distilled water, filtered, and the filtrate was adsorbed on a 4kg HPD300 type macroporous resin column, and the adsorption was repeated three times. For the first time, use 4 times the column volume of distilled water and 5 times t...

Embodiment 3

[0037] Example 3 Preparation of total phenolic acid extract of hydrangea flower leaves (3)

[0038] The dried medicinal materials of 2kg of pulverized hydrangea leaves were added with 90% ethanol at a weight ratio of 1:20 in the ratio of medicinal materials: ethanol solution for 24 hours, and then heated and refluxed for 3 times, each extraction time was 3h, 3h , 3h. Combine the three extracts, filter, recover the solvent, and concentrate to a relative density of 1.00-1.20. The concentrated liquid was extracted three times with petroleum ether and n-butanol respectively, and the concentrated liquid: solvent weight ratio was 1:1. The three n-butanol extracts were combined and concentrated to obtain 167 g of n-butanol extract. The n-butanol extract was dissolved in 2.0L of distilled water, filtered, and the filtrate was adsorbed on a 3kg D101 macroporous resin column, and the adsorption was repeated three times. For the first time, use 6 times the column volume of distilled wate...

Abstract

The invention belongs to the field of traditional Chinese medicine and natural medicine pharmacy, and relates to hydrangea leaf extract and its pharmaceutical composition, preparation method and application. The purpose of the present invention is to provide the application of the total phenolic acid extract of hydrangea leaves in the preparation of medicine for treating thyroid cancer. The preparation method of the hydrangea leaf extract of the present invention is as follows: (1) take the hydrangea leaf, pulverize, add a solvent to soak and extract; (2) filter, and concentrate the filtrate for later use; (3) extract the concentrated solution to obtain an extract, extract Add water and filter to obtain the filtrate; (4) adsorb the filtrate to a macroporous resin column, successively use distilled water, 10-20% ethanol aqueous solution, 20-30% ethanol for elution, and 30-40% ethanol for elution, and collect 30-40 % ethanol eluate, concentrated and dried, crushed, and sieved to obtain Hydrangea leaf extract. The total phenolic acid content in the hydrangea leaf total phenolic acid extract is as high as 40%, and the quality is stable and controllable. The extract has a clear therapeutic effect on thyroid cancer through in vivo and in vitro anti-thyroid cancer pharmacological tests.
