Problems solved by technology

[0003] At present, the aboveground parts of Jerusalem artichoke flowers and Jerusalem artichoke leaves, as well as the underground part of Jerusalem artichoke tubers are widely used, but the fibrous roots of the underground parts are not currently researched and utilized, and are directly wasted, which reduces the degree of development and utilization of the whole plant of Jerusalem artichoke, resulting in resource loss. waste
At present, there are related studies on the use of Jerusalem artichoke leaf extract for bactericidal and antibacterial aspects, but there is no research on the use of Jerusalem artichoke root extract, and there is no research on the use of Jerusalem artichoke root extract for antibacterial activity

Description

technical field [0001] The invention relates to the technical field of Jerusalem artichoke sterilization, in particular to an extract of Jerusalem artichoke root and its antibacterial activity application. Background technique [0002] Jerusalem artichoke is a cultivar that can form underground tubers in the genus Sunflower of the Compositae family. It is also known as foreign ginger, Jerusalem artichoke, devil ginger, etc., and its scientific name is Helianthus tuberosus L. It is a perennial herbaceous plant with a height of 1-3 meters. , with massive underground tubers and fibrous roots. Jerusalem artichoke likes warmth, but is cold-resistant; likes humidity, but is drought-tolerant; likes fertility, but is resistant to barrenness, and saline-alkali. It is planted in most areas of my country, and can also be cultivated in coastal saline soil and irrigated with seawater. The aboveground stems, leaves and underground tubers of Jerusalem artichoke are excellent feed. The und...
