Example Embodiment

[0020] The present invention uses Tween-80 to prepare a 50% solution of industrial alcohol extracts of 200 plant-derived traditional Chinese medicines, and conducts an in vitro killing test of rabbit itchy mites (Psoroptes cuniculi), which can kill all the tested mites within 240 minutes There are 35 flavors of mites. Among them, clove has a miticidal time of only 15 minutes, showing high miticidal activity. Further through solvent fraction separation, column chromatography separation, thin layer chromatography purification and activity tracking, a highly effective miticidal activity is obtained. The active ingredient, its thin-layer chromatography behavior and acaricidal activity are consistent with the eugenol reference substance, and this highly effective acaricidal active ingredient is determined to be eugenol.

Abstract

A plant extract used as miticide in the form of liquid is prepared from the powder of raw plant through immersing in industrial alcohol, thermal reflux extracting in water bath twice, collecting liquid extract, vacuum recovering of solvent, and dissolving in tween-80. Said plant extract may be caryophyllene alcohol containing eugenol.

Description

1. Technical field: [0001] The invention relates to a high-efficiency, low-toxicity and environment-friendly plant extract for killing acarids, in particular to a plant extract for killing acarids. 2. Background technology: [0002] Acariasis is an ectoparasitic disease caused by parasitic mites of the pruritic acaridae and scabies acarids on the surface or in the epidermis of animals. The production performance of sick animals is reduced, the digestion and absorption function is reduced, and they become emaciated, and even cause individual or large numbers of animals to lose weight. death, but also a threat to human health. Acarid disease not only directly affects the development of animal husbandry, increases the cost of feeding and treatment, and causes serious losses to animal husbandry production, but also endangers leather processing and other related industries. Nodules are formed on the surface, which directly affects the utilization value of leather. Livestock and...
