Embodiment Construction

[0012] The present invention provides the entire process of extracting effective ingredients from water peanuts as follows:

[0013] Collection and primary processing of water peanuts: wash with water and dry. When in use, place it in a drying box for drying, use a small grinder to pulverize it into powder, and pass through a 60-mesh sieve for use.

[0014] Extraction of active ingredients of water peanut: The effective ingredients of water peanut are extracted by microwave-assisted ethanol extraction. The specific method is: weigh 1 kilogram of water peanut hay powder, add a certain amount of distilled water, heat it with microwave for 5 minutes, and then add ethanol solvent , Make the ethanol concentration reach 75%, filter for 24 hours after leaching, repeat the extraction 3 times, combine the extracts, distill under reduced pressure to recover the ethanol, the concentrated liquid is fixed in a 500mL volumetric flask for use.

[0015] Preparation of test bacterial solution: The...

Abstract

A medicine for preventing and treating the disease of aquatic animals is prepared from Alternanthera philoxeroxides through extracting to obtain its coarse extract.

Description

1. Technical Field [0001] The invention belongs to the technical field of medicine preparation for preventing and treating diseases of aquatic animals. 2. Background technology [0002] In aquaculture, people often use a large number of chemical synthetic drugs to prevent and treat aquatic animal diseases. Although they have achieved obvious curative effects, repeated use of chemical drugs can cause pathogenic microorganisms to develop drug resistance and cause "three causes" (carcinogenic, teratogenic) And mutagenicity) and other issues. This not only harms the growth and development of aquatic animals, but also the food safety of aquatic products is worrying, so people began to use Chinese herbal medicine to treat aquatic animal diseases (Song Xuehong et al., 2001 and Gao Hanjiao et al., 1996). Water peanut Alternanthera philoxeroidesGriseb. belongs to Amaranthaceae, Alternanthera, perennial amphibious herb. Commonly known as revolutionary grass, hollow amaranth, Alternanthera ...
