Embodiment 1

[0007] Embodiment 1, bamboo leaf total flavonoids extraction process:

[0008] 1. Determination of ethanol concentration

[0009] Weigh 19 dianthus leaf powder at 75. C, the ratio of solid to liquid is 1:20, leaching for 2 hours, the pH is not adjusted, under the condition of leaching once, leaching is carried out with 10%-90% (v / v) ethanol in turn, the absorbance measured at 510rim Relationship with ethanol concentration.

[0010] 2. Selection of material-to-liquid ratio

[0011] Weigh Dianthus diaphylla leaf powder 19, select the volume of extraction solvent according to the ratio of material to liquid from 1:15 to 1:40 (w / v), extract at 75°C with 65% 7, alcohol for 2 hours, and adjust the pH , leaching 1 time, the relationship between the total absorbance value of the solution after leaching (per milliliter of leaching solution absorbance value X total volume after solvent leaching) and the initial volume of the solvent was measured at 510nm.

[0012] 3. Selection of ex...

Embodiment 2

[0020] Embodiment 2, refining process of total flavonoids of Dianthus diaphylla leaves:

[0021] 1. For leakage under different adsorption flow rates, take a certain volume of ADS-17 wet resin and pack it into a column so that the ratio of diameter to height is 1:5. By adjusting the flow rate of the constant flow pump, the adsorption flow rate of the upper column sample liquid should be selected. The latest adsorption flow rate at the leakage point is appropriate. Therefore, under the condition that the concentration of the sample liquid is 13.79 "g / mL, and the volume of the sample liquid is 100 mL, the leakage conditions at three adsorption flow rates of 1 mL / min, 2 mL / min, and 4 mL / min are compared.

[0022] 2 Leakage under different diameter-to-height ratios, under the condition of a certain resin volume, by selecting packed columns with different column diameters, different diameter-to-height ratios are obtained to observe the impact on the leakage point, which is also a f...

Abstract

The invention relates to an extraction technology and purification method for Dianthus chinensis L. var. subulifolius leaf total flavonoids. By adopting macroporous adsorption resin and utilizing ADS series macroporous adsorption resin, the invention puts forward ADS-17 resin with good purification refining functions on bamboo leaf flavonoid, opens up a new way for the refining technology of bamboo leaf flavonoid, also greatly reduces the organic solvent consumption, shortens the production cycle, accordingly reduces the production cost, and improves the market competitiveness of the art product.

Description

technical field [0001] The invention relates to a process for extracting compounds, in particular to a process for extracting and purifying total flavonoids from Dianthus persicae. Background technique [0002] Bamboo is a perennial evergreen plant of Gramineae, and it is one of the most valuable plants in the world today. There are more than 70 genera and more than 1,200 species in the world, and the bamboo forest area is about 20 million km2 (300 million mu). my country is located in the center of the world's bamboo distribution. It is known as the "Bamboo Kingdom" and has extremely rich bamboo resources. Among them, Bamboo is the main economic bamboo species cultivated in my country, with high economic value, wide application, large area, and the largest production of commercial bamboo. The development of bamboo leaf resources has extremely important economic and social significance. The whole body of bamboo is a treasure, and it is one of the most valuable plants in the...
