Embodiment 1

[0024] 1. Raw materials: The research results of the dynamic change of chlorogenic acid content in maple leaves of Yuanbao with seasons show that the content of chlorogenic acid in maple leaves of Yuanbao in Shaanxi Guanzhong area is the highest from June to August, and the chlorogenic acid in leaves decreases with the growth of tree age The tendency is that young trees are significantly higher than old trees, especially the chlorogenic acid content in the leaves of 1-year-old seedlings is 6.99%; therefore, harvesting the leaves of 1-year-old Yuanbao Maple seedlings between June and August can obtain the best preparation method for chlorogenic acid. raw material.

[0025] 2. Crush: Crush 1000kg of maple ingots into 8-10 meshes.

[0026] 3. Extraction:

[0027] Chlorogenic acid is a phenylpropanoid derivative, which is lively in nature and easy to oxidize and decompose. When helping to extract, the temperature, time and pH value during extraction should be controlled as much a...

Embodiment 2

[0035] Yuanbao Maple Leaf 1000g, crushed to 8-10 mesh, placed in a 100-liter circulating ultrasonic extraction device to extract chlorogenic acid, the organic solution in the circulating ultrasonic extraction device is 60% acetone, because chlorogenic acid is a phenylpropanoid derivative , the nature is active, easy to oxidize and decompose, so the extraction temperature should be controlled at 40°C, the extraction time should be controlled at 30 minutes, and the pH value should be controlled at 5-6. Controlled at 4-5, the flow rate of adsorption liquid is 8-10ml / s. The flow rate of the eluent is 5-6ml / s; the chlorogenic acid in the resin is dissolved by ethanol to obtain the chlorogenic acid eluate, and then it is concentrated in an external circulation under reduced pressure, the temperature is controlled at 50°C, and the heating time is controlled for 40 minutes , to get 40% of the finished dry powder.

Abstract

The invention relates to a process for extracting medicinal herb component, specifically a process for extracting chlorogenic acid from shoe-shaped ingot maple leaves, wherein low-temperature extraction is employed and under the conditions of controlled time, pH value and feed liquid ratio. The advantages of the process are high leaching ratio, simplicity of operation, low cost, and no toxin.

Description

1. Technical field: [0001] The invention relates to a process for extracting medicinal plant components, in particular to a process for extracting chlorogenic acid from ingot maple leaves. 2. Technical background: [0002] Chlorogenic acid is a phenylpropanoid substance formed by plants in the process of aerobic respiration. It has various pharmacological effects such as antibacterial, choleretic, blood circulation, and meridian. With the increasing development of society, pharmaceutical manufacturers and health food manufacturers are more interested in The demand for chlorogenic acid is also increasing day by day, and the purity of chlorogenic acid is getting higher and higher; in industry, most of foreign countries are extracted from coffee beans, and now it has been transferred to extract from Eucommia leaves and honeysuckle buds. It is extracted from Eucommia leaves and honeysuckle buds. Generally, boiling extraction method, boiling alcohol precipitation method, 70% eth...
