Embodiment 1

[0029] Detection of anti-ulcerative colitis drug components of the present invention

[0030] 1. Experimental method

[0031] The content of the main component of the aescin drug is determined, and HPLC is used for detection, and the chromatographic conditions are as follows:

[0032] Chromatographic column: Agilent 5HC-C18, 4.6*250mm, 5.0μm;

[0033] Column temperature: 30°C;

[0034] UV detection wavelength: 220nm;

[0035] Flow rate: 1.0ml / min;

[0036] Mobile phase: A, 0.1% phosphoric acid aqueous solution; B, acetonitrile;

[0037] Isocratic elution: B: 42%.

[0038] 2. Experimental results

[0039] The HPLC chromatograms of the main components are shown in figure 1 and content see figure 2 . The HPLC chromatogram of aescin and the chromatographic peak information table of each component are shown in the table. Among them, the content of the main component aescin A in aescin accounts for 30.42% of the total content, the content of aescin B accounts for 15.38% o...

Abstract

The invention discloses the use of aescin in the preparation of medicine for treating ulcerative colitis. Aescin obtained from the traditional Chinese medicine Su Luozi has the functions of clearing away heat, stopping bleeding, reducing inflammation, and dispelling blood stasis, and has significant preventive and therapeutic effects on abdominal pain, diarrhea, mucus, pus, and bloody stools caused by ulcerative colitis.

Description

technical field [0001] The invention discloses the use of a traditional Chinese medicine extract, in particular to the use of aescin in the preparation of medicines for treating ulcerative colitis. Background technique [0002] Ulcerative colitis (UC) is a chronic nonspecific inflammatory disease that belongs to the category of autoimmune diseases. UC is refractory, prone to recurrence, deterioration and canceration, and has been listed as one of the modern intractable diseases by the World Health Organization (WHO). UC is a chronic non-specific inflammatory disease of the colon and rectum whose etiology is not yet clear, and the lesions are limited to the mucosa and submucosa of the large intestine. The lesions are mostly located in the sigmoid colon and rectum, and can also extend to the descending colon, or even the entire colon. The course of the disease is long and often recurrent. The disease is seen at any age, but it is most common in 20-30 years old. Diarrhea-ty...
