Abstract

The invention relates to an antibacterial, anti-inflammatory and antioxidant carex meyeriana extract as well as a preparation method and application thereof, and belongs to the field of phytochemistry. The preparation method comprises the following steps of crushing carex meyeriana, adding 50-95% ethanol in an amount which is 8-12 times the volume mass of the carex meyeriana, soaking for 20-60 minutes, carrying out reflux extraction twice for 20-60 minutes each time, filtering, merging filtrates, concentrating and drying to obtain the carex meyeriana extract. The invention discloses application of the antibacterial, anti-inflammatory and antioxidant carex meyeriana extract in preparation of an antibacterial agent, an anti-inflammatory agent or an antioxidant. The antibacterial, anti-inflammatory, antioxidant and carex meyeriana extract disclosed by the invention is derived from cyperaceae Carex Linn. plant carex meyeriana, is an ethanol extract of whole grass of carex meyeriana, and has good antibacterial, anti-inflammatory and antioxidant effects; and the extract has an inhibiting effect on gram-negative bacteria, gram-positive bacteria, fungus typical pathogenic bacteria such asstaphylococcus aureus, escherichia coli, pseudomonas aeruginosa, candida albicans and the like.

Description

technical field [0001] The invention belongs to the technical field of phytochemistry, and relates to the field of natural product extracts and preparations, in particular to an extract of Uralia sativa and its application, and to a plant-derived antibacterial, anti-inflammatory, and antioxidant plant extract and its preparation method and application . Background technique [0002] Candida albicans is the main pathogen of candidiasis. Candida albicans in the oral cavity is generally not harmful to healthy individuals, and its growth is inhibited by the immune barrier and other commensal microorganisms in the niche. However, when these barriers subside, C. albicans overgrowth can cause mild local discomfort and altered taste, which can lead to serious systemic infection, especially in young children, the elderly, and immunocompromised populations with high morbidity and mortality. If Candida albicans grows unchecked in the oral cavity, it can lead to oral candidiasis, whic...
