Problems solved by technology

However, on the one hand, different preparation methods of extracts lead to different compositions of active components, so the antibacterial effects of extracts prepared by different extraction methods are significantly different; The antibacterial effect of different strains was significantly different
Therefore, the antibacterial mechanism of purslane has not yet been clearly determined, which will definitely affect the further development and application of purslane

Abstract

The present invention relates to applications of Chinese herb plants, particularly to a portulaca oleracea l extract and applications thereof. The preparation method of the portulaca oleracea l extract comprises: crushing portulaca oleracea l herb, screening, and extracting the total flavone from the portulaca oleracea l herb by using an ultrasonic extraction method. According to the present invention, the portulaca oleracea l extract can inhibit pathogenic bacteria, kill bacteria, and induce apoptosis of pathogenic bacteria.

Description

technical field [0001] The invention relates to the application of plant Chinese herbal medicine, in particular to extract of purslane and application thereof. Background technique [0002] In recent years, due to the wide application of chemical antibacterial drugs such as antibiotics, the rapid growth of drug-resistant bacteria has made the effective treatment of infectious diseases a serious problem that plagues human and animal health. Therefore, research on how to eliminate bacterial resistance has become a concern for everyone. hotspots. To eliminate bacterial resistance, in the past, various chemical and physical treatment methods were mainly adopted at home and abroad, but the chemical drugs used in the treatment process have severe side effects and are not suitable for human or animal organisms. [0003] Purslane (Portulaca oleracea L.) is a plant of the family Portulaca oleracea, clearing away heat and detoxification, diuresis and dehumidification, dispersing bloo...
