The application discloses a preparation method of cherimoya leaf extract and belongs to the technical field of natural medicine extraction and preparation. The conventional preparation method of the cherimoya leaf extract in the prior art has limited bioavailability of the extract, and lacks a systematic method for effectively enriching specific active components of the extract and stably encapsulating the specific active components in a suitable delivery system. The preparation method provided by the application comprises the following steps: crushing dried cherimoya leaves, refluxing and extracting the dried cherimoya leaves with an ethanol aqueous solution, and concentrating the extract; adding ethyl acetate to the concentrated solution to perform extraction; mixing the obtained ethyl acetate extraction phase with a phospholipid aqueous dispersion liquid composed of phosphatidylcholine and phosphatidylethanolamine in a specific ratio; performing high-pressure homogenization treatment to obtain a nanoliposome suspension liquid; and finally performing spray drying to obtain an extract powder. The extract prepared by the method can be used for preparing a medicine for treating type 2 diabetes.

The application discloses a pesticide composition containing annonaceous acetogenins and triflumuron and application thereof, and belongs to the technical field of pesticides. Effective components of the composition are the mass ratio of 1:10 to 20:1 of the annonaceous acetogenins and the triflumuron, wherein the annonaceous acetogenins are ortho-bis-tetrahydrofuran lactones extracted from seeds of Annona squamosa, and the purity is greater than or equal to 90%. The total mass percentage content of the effective components in the composition is 10% to 30%, and the rest is a pesticide adjuvant. The composition can be prepared into various dosage forms such as suspending agents, emulsifiable concentrates, suspending seed-coating agents, soluble granules or micro-capsule suspending-suspending agents. The two effective components with different action mechanisms are scientifically compounded, and the composition shows a significant synergistic effect on piercing-sucking mouthpart pests such as wheat aphids, corn aphids and brown planthoppers, and the highest co-toxicity coefficient (CTC) can reach 176.31. The composition can effectively reduce the field chemical pesticide dosage, delay the development of pest resistance and reduce pesticide residues, and has the characteristics of high efficiency, low residue and environmental friendliness.

The invention provides a selenium-rich annona squamosa production method which comprises the following steps: S1, in an annona squamosa flower bud differentiation period, carrying out selenium solution irrigation treatment on annona squamosa trees for three times at an interval of about 30 days; s2, in the flowering and fruit-setting period of the annona squamosa, spraying a selenium solution to the annona squamosa tree twice at an interval of about 30 days; s3, synchronously implementing irrigation treatment in the step S1 and spraying treatment in the step S2 on the annona squamosa trees. The selenium content of the produced annona squamosa fruits is remarkably increased, the functional value of the selenium element is added on the basis that original nutrition is reserved, the annona squamosa fruits are transformed into special functional fruits, the oxidation resistance of the fruits is improved to different degrees, and the comprehensive quality is improved.

The invention discloses an annona squamosa fruit fresh-keeping agent, fresh-keeping paper, a fresh-keeping sheet and a fresh-keeping method thereof, and belongs to the technical field of fruit and vegetable fresh-keeping. According to the preservative, a sodium carboxymethyl cellulose solution is used as a film-forming substrate and is compounded with 1-methylcyclopropene, salicylic acid, spermine, gallic acid, peppermint essential oil, eleocharis tuberosa peel extract and other bacteriostatic preservative components, and long-acting preservation of annona squamosa is achieved through a multi-target synergistic effect.
