The invention discloses a composition for controlling feather louses and application of the composition in preparation of a pigeon nest inner pad with insect-expelling and mildew-proof functions, and belongs to the technical field of livestock and poultry breeding appliances. The composition for controlling feather louses comprises acorus calamus leaves and artemisia apiacea leaves. The inner pad is a bowl-shaped inner pad which can be placed in a hard pigeon nest basin, adopts a composite structure design, adopts a bowl-shaped slow-release carrier layer woven by reed stalks, and is filled with a compound active filler which is formed by compounding and crushing acorus calamus leaves and sweet wormwood leaves. The key point is that through the specific structure, the physical slow release characteristic of the reed stalks is combined with the synergistic gain effect of the acorus calamus leaves and the artemisia apiacea leaves, so that the inner pad can continuously and efficiently exert the dual effects of expelling parasites and preventing mildew in the egg laying, hatching and brooding periods of pigeons.

This invention discloses a method for extracting Artemisia annua extract from Artemisia annua leaves and its application. The method includes the following steps: taking Artemisia annua leaves, packaging and drying them; placing the dried Artemisia annua leaves into a wide-mouth bottle, ensuring the leaves are fully soaked, and then placing the fully soaked leaves into an ultrasonic instrument for ultrasonic-assisted extraction; after ultrasonic-assisted extraction, filtering to obtain filter residue, and then repeating ultrasonic-assisted extraction to obtain all the filtrate; rotary evaporating all the filtrate to obtain a concentrated solution, which is then dissolved again in an appropriate amount of pure water, subjected to chromatographic separation, and gradient elution; collecting the specified eluent fraction, and then rotary evaporating it again to obtain Artemisia annua extract. This invention provides a method for extracting Artemisia annua extract from Artemisia annua leaves and its application, which can extract other active ingredients from Artemisia annua, improve the bioavailability of other active ingredients in Artemisia annua, and expand its application in pharmaceuticals and cosmetics.
