Problems solved by technology

There are fewer literature reports related to cockroach antibacterial activity. Among them, people such as Wang Kui found that after Periplaneta americana was extracted with petroleum ether, the petroleum ether layer was discarded, and the ethyl acetate extract of its dregs was the antibacterial agent of Periplaneta americana. Bacteria active site, which has strong antibacterial activity against Gram-positive bacteria, but inactive against Gram-negative bacteria (Wang Kui, et al., Isolation and Antibacterial Activity Analysis of Periplaneta americana Ethyl Acetate Extract, Forestry Scientific Research, 20132,26(2))

Abstract

The invention discloses an antibacterial active part of a cockroach, and an extraction method and use thereof. Researches in the invention unexpectedly find that a petroleum ether extraction part of the cockroach has good inhibitory activity to both tested gram-positive bacterium and gram-negative bacterium; furthermore, the activity of the petroleum ether extraction part of the cockroach is obviously prior to that of an ethyl acetate extraction part; and an n-butyl alcohol extraction part and a 95% v / v ethanol extraction part do not have obvious antibacterial activity.

Description

technical field [0001] The invention relates to a cockroach extract, a preparation method and application thereof. Background technique [0002] Cockroach, recorded in "Shen Nong's Materia Medica", "Famous Doctors", "Compendium of Materia Medica" and other medical books, tastes salty, cold in nature, has the effects of dispelling blood stasis, dissolving accumulation, and detoxifying. It is a traditional medicinal insect [1] .
