Abstract

The invention belongs to the field of traditional Chinese medicines, and particularly provides a callicarpa nudiflora extract composition for treating a hand-foot-and-mouth disease. According to the parts by weight, the composition is prepared by 22-40 parts of total callicarpa nudiflora flavone, 20-26 parts of total callicarpa nudiflora phenolic acid, and 40-50 parts of total callicarpa nudifloraphenylethanoid glycosides. The invention further discloses an application of the composition. Three components used by the composition are extracted from callicarpa nudiflora, and the components of the composition are clear. Through the synergistic effect of each component, the composition has the good efficacy of treating and / or preventing the hand-foot-and-mouth disease.

Description

technical field [0001] The present invention relates to an extract composition and application thereof, in particular to an extract composition of Auranthus nudica with the effect of treating hand, foot and mouth disease and an application thereof. Background technique [0002] Hand, foot, and mouth disease (HFMD) is a common acute infectious disease in pediatrics, which often occurs in preschool children. The clinical manifestations are fever, sore throat, oral herpes, rash on hands and / or feet or other parts, herpes or small ulcers , can be cured in about 7 days. However, there are still some children with severe complications such as encephalitis and pulmonary edema. The main harm of hand, foot and mouth disease to young children and infants is the high mortality rate and high disability rate of severe and critical hand, foot and mouth disease. , especially HFMD patients with brainstem encephalitis, neurogenic pulmonary edema, and cardiorespiratory failure. HFMD is high...
