Embodiment 1

[0019] Take 5000g of the raw material of Pseudomonas gentiana, first reflux extraction with 75% ethanol 20 times the weight of the raw material for 3 times, each extraction for 1.5 hours, combine the above extracts, concentrate under reduced pressure to a paste, and then suspend in water to obtain a suspension liquid medicine.

[0020] After suspending the obtained suspension medicinal solution with water, load it to D101 type macroporous adsorption resin column chromatography (resin weight 80g, column volume 100ml, column diameter: column height=1: 2) for adsorption, and the sample loading flow rate is per hour 1.2 times the column volume, rinse the column with distilled water after loading the sample until the water eluent is nearly colorless, discard the water eluate, and use 6 times the column volume to elute with 60% ethanol aqueous solution, and the flow rate of the eluent is controlled at 0.5 times the column volume per hour, during the elution process, use TCL to detec...

Embodiment 2

[0022] Take 5000g of the raw material of Pseudomonas gentiana, first reflux extraction with 75% ethanol 20 times the weight of the raw material for 3 times, each extraction for 1.5 hours, combine the above extracts, concentrate under reduced pressure to a paste, and then suspend in water to obtain a suspension liquid medicine.

[0023] After the suspending medicinal liquid of gained is suspended with water, load sample to AB-8 type macroporous adsorption resin column chromatography (resin weighs 80g, and column volume 100ml, column diameter: column height=1: 2) is adsorbed, and sample loading flow rate is 1.2 times the column volume per hour, wash the column with distilled water after loading the sample, until the water eluent is nearly colorless, discard the water eluate, and elute with 6 times the column volume containing 60% ethanol aqueous solution, the flow rate of the eluent is The column volume is controlled at 0.5 times per hour. During the elution process, TCL is used...

Embodiment 3

[0025] Take 5000g of the raw material of Pseudomonas gentiana, first reflux extraction with 75% ethanol 20 times the weight of the raw material for 3 times, each extraction for 1.5 hours, combine the above extracts, concentrate under reduced pressure to a paste, and then suspend in water to obtain a suspension liquid medicine.

[0026] After suspending the obtained suspension medicinal solution with water, load it to H103 type macroporous adsorption resin column chromatography (resin weight 80g, column volume 100ml, column diameter: column height=1: 2) for adsorption, and the sample loading flow rate is per hour 1.2 times the column volume, rinse the column with distilled water after loading the sample until the water eluent is nearly colorless, discard the water eluate, and use 6 times the column volume to elute with 60% ethanol aqueous solution, and the flow rate of the eluent is controlled at 0.5 times the column volume per hour, during the elution process, use TCL to detec...

Abstract

The invention discloses a gentianella acuta extract for treating arrhythmia. The extract consists of ketone compounds, iridoid compounds and flavonoid compounds. The invention also discloses a preparation method and application of the gentianella acuta extract. The gentianella acuta extract disclosed by the invention comprises 20-40% of ketone compounds based on the total weight of the extract, 5-15% of iridoid compounds based on the total weight and a small amount of flavonoid compounds, wherein the ketone compounds include 1,3,5,8-tetrahydroxy tetrahydro-ketone, nor-chiratin, 3,8-O-beta-D-diglucopyranose-1,5-dihydroxy-keton, nor-bellidifolin, 1,3,5-trihydroxy-ketone, 2-O-beta-D-n glucopyranose-1-hydroxy-5,6-dimethoxy-ketone and 1,2,8-trihydroxy-5,6-dimethoxy-ketone; the iridoid compounds include gentiopicroside, swertiamarin and decentapicrin; the flavonoid compounds include isoorientin and isovitexin. Chemical and pharmacological experiments prove that the gentianella acuta extract can be used for treating arrhythmia caused by coronary heart disease and ischemic heart disease. The gentianella acuta extract can be made into drugs of various dosage forms independently or by compatible combination or can be used as a raw medicine.
