Embodiment 1

[0042] Example 1 Preparation of kidney tea phenolic acid extract T1 of the present invention Take 1000 grams of kidney tea (Clerodendranthus Spicatus (Thunb) CYWU), after pulverization, reflux twice with 50% ethanol for 2 hours each time. The reflux filtrates were combined, and the ethanol was distilled off under reduced pressure to obtain a concentrated aqueous solution, which was diluted with deionized water, centrifuged, and set aside. Get D-101 type macroporous resin packing column, above-mentioned aqueous solution passes through this macroporous resin column with the flow velocity of 20 milliliters / minute, then wash column with 500 milliliters of deionized water with the flow velocity of 20 milliliters / minute, then use 10% ethanol Eluted, discarded, and then eluted with 50% ethanol. The eluents were combined, concentrated under reduced pressure, and dried in vacuo to obtain 39.8 g of kidney tea phenolic acid extract T1 dry powder (yield about 4%). The kidney tea phenolic ...

Embodiment 2

[0043] Example 2 Preparation of Kidney tea phenolic acid extract T2 of the present invention Take 1000 grams of Kidney tea (Clerodendranthus Spicatus (Thunb) CYWU), after pulverization, reflux twice with 30% ethanol for 2 hours each time. The reflux filtrates were combined, and the ethanol was distilled off under reduced pressure to obtain a concentrated aqueous solution, which was diluted with deionized water, centrifuged, and set aside. Get D-101 type macroporous resin packing column, above-mentioned aqueous solution passes through this macroporous resin column with the flow velocity of 20 milliliters / minute, then wash column with 500 milliliters of deionized water with the flow velocity of 20 milliliters / minute, then use 10% ethanol Eluted, discarded, and then eluted with 30% ethanol. The eluents were combined, concentrated under reduced pressure, and dried in vacuo to obtain 49.8 g of kidney tea phenolic acid extract T1 dry powder (yield about 5%). The kidney tea phenolic ...

Embodiment 3

[0044] Example 3 Preparation of kidney tea phenolic acid extract T3 of the present invention Take 1000 grams of kidney tea (Clerodendranthus Spicatus (Thunb) CYWU), after crushing, reflux twice with 50% ethanol for 4 hours each time. The reflux filtrates were combined, and the ethanol was distilled off under reduced pressure to obtain a concentrated aqueous solution, which was diluted with deionized water, centrifuged, and set aside. Get D-101 type macroporous resin packing column, above-mentioned aqueous solution passes through this macroporous resin column with the flow velocity of 20 milliliters / minute, then wash column with 500 milliliters of deionized water with the flow velocity of 20 milliliters / minute, then use 10% ethanol Eluted, discarded, and then eluted with 40% ethanol. The eluents were combined, concentrated under reduced pressure, and dried in vacuo to obtain 45.8 g of kidney tea phenolic acid extract T1 dry powder (yield about 4.5%). The kidney tea phenolic aci...

Abstract

The invention discloses a water soluble phenolic acid extract which is obtained by extracting from a medical plant of a clerodendranthus spicatus by the chemical method. The pharmacological experiment testifies that the extract has strong physiological activity and especially has strong physiological activity of resisting the generation of uric acid, and the extract is used for remedying the pain-louse and has good effect of the treatment towards the urinary tract infection or the urinary tract concretion and has little toxic and side effect.

Description

technical field [0001] The invention relates to an extract of medicinal raw materials, a preparation method and application thereof. Specifically, it refers to the water-soluble phenolic acid extract obtained from the medicinal raw material kidney tea (Clerodendranthus Spicatus (Thunb) CYWU), which has good physiological activity after pharmacological tests. Background technique [0002] Kidney tea (Clerodendranthus Spicatus (Thunb) CYWU) is a plant of the genus lerodendranthus of the Labiatae family, also known as cat's whiskers. It is believed by the people that the whole plant has diuretic, antibacterial, anti-inflammatory, stone-dissolving, and stone-dispelling effects. It is often used for acute and chronic nephritis. , cystitis, urinary tract stones, pharyngitis and rheumatoid arthritis. The chemical composition of kidney tea (Clerodendranthus Spicatus (Thunb) CYWU) is mainly composed of fat-soluble components and water-soluble components. Among them, the fat-soluble...
