Abstract

The invention relates to a preparation method for acquiring effective substance groups with anti-ulcerative-colitis activity by separation from callicarpa kwangtungensis and compound extract thereof and application of the effective substance groups to preparation of medicines for treating immune inflammations. Particularly, the effective substance groups are acquired by adoption of a membrane separation focused separation technology and used for preparation of medicines for treating immune inflammations including ulcerative colitis.

Description

technical field [0001] The invention discloses a traditional Chinese medicine extract for treating ulcerative colitis, which belongs to the field of traditional Chinese medicine. Background technique [0002] Ulcerative colitis (UC) is a chronic non-specific inflammatory disease that belongs to the category of autoimmune diseases. Because UC is difficult to cure, and is prone to recurrence, deterioration and canceration, it brings great physical and mental pain to patients, and has been listed as one of the modern intractable diseases by the World Health Organization (WHO). So far, the therapeutic drugs for UC mainly include traditional aminosalicylic acids, steroid hormones, immunosuppressants, and new biological agents. Traditional treatment drugs have limited therapeutic effect, and the recurrence rate is high after drug withdrawal. Newer biologics, such as tumor necrosis factor-α (TNF-α) monoclonal antibodies, can alleviate intestinal inflammation and promote mucosal r...
