Periploca sepium fat soluble component extract no public pollution fishing medicine and its preparing method

Abstract

The present invention discloses fish medicine with the liposoluble extract of Periploca sepium as main component. The technological key points include extracting liposoluble extract with Periploca sepium root and stem bark and through crushing, methanol reflux extraction at 60-70 deg c, and concentrating the extracted liquid to 10-15 wt% of material; and compounding the fish medicine with liposoluble extract of Periploca sepium as active component in 20-75 wt%, surfactant in 3-10 wt% and solvent as the rest part. Compared with chemical fish medicine, the fish medicine with the liposoluble extract of Periploca sepium as main component has the advantages of no influence on aquatic product quality, no residue, no pollution, less drug resistance, safety on aquatic product, etc.

Description

technical field

[0001] The invention belongs to an insecticide and a control agent in the aquaculture industry, in particular to a fish parasitic monogenetic trematode control agent mainly composed of Periploca sepium extract. Background technique
