The invention discloses a plant type vapor phase copper corrosion inhibitor and a preparation method thereof. The volatile matter of the corrosion inhibitor contains 5wt%-20wt% of dipropenyl trisulfide, 2wt%-10wt% of dipropenyl disulfide, 2wt%-10wt% of 1-oxygen-4,6-disulfide Azoctane‑5‑thione and 30wt%‑50wt% eucalyptol. It is a mixture of garlic extract and bay leaf extract in a weight ratio of 3:1. The plant-type gas-phase copper corrosion inhibitor provided by the invention has obvious corrosion inhibition effect, simple preparation method, safety, non-toxicity and environmental friendliness.

The invention relates to a controlled-release hydrogen sulfide donor. The donor is obtained by reacting diallyl trisulfide with an ordered mesoporous silicon dioxide nanoparticle materials. The invention also provides a preparation method and application of the hydrogen sulfide donor. The controlled-release hydrogen sulfide donor is capable of slowly releasing medium-concentration hydrogen sulfide, can be regulated by use of glutathione and has no obvious cytotoxicity; as a result, the controlled-release hydrogen sulfide donor is an ideal hydrogen sulfide donor for in-vivo and in-vitro experiments and clinical application.

The invention provides an environmentally friendly fertilizer for pest dispelling, pest killing, bacterium inhibiting and bacterium killing, and a production technology and a use method thereof. The fertilizer is a neutral or weakly acidic fertilizer, and contains a diallyl disulfide and diallyl trisulfide mixture. The pH value of a saturated aqueous solution of the fertilizer can be 5-7, and preferably 6.5-7. The fertilizer can have the following one or more characteristics: 1, a compound fertilizer or a composite fertilizer; 2, a slow release fertilizer or a controlled release fertilizer; 3, an organic fertilizer or an inorganic fertilizer or an organic-inorganic compound fertilizer; 4, urea, a urea-ammonium mixed nitrogen fertilizer and polypeptide urea; 5, monoammonium phosphate and diammonium phosphate; and 6, potassium chloride and potassium sulfate. The fertilizer can provide crop nutrients, effectively purifies soil and control the diseases and insect pests of crops, and diallyl disulfide and diallyl trisulfide are from garlic extracts, are most safe biological pesticides proved in the laboratory at present, have no toxic side effects, no drug residual and no drug resistance, and are best additives substituting antibiotics to produce nuisance free products.

A sustained-release composition is provided in the present disclosure for producing a therapeutic gas, such as hydrogen sulfide or hydrogen. The sustained-release composition includes a precursor and a carrier. The precursor is diallyl trisulfide or magnesium, and the carrier includes a poly lactic-co-glycolic acid copolymer for carrying the precursor with an efficient amount.

The invention discloses a preparation method of hydrogen sulfide sustained-release gel and its application in the preparation of medicines for treating diabetic skin ulcers, including preparing cyclodextrin inclusion compound DATS@CD containing diallyl trisulfide respectively DATS@CD‑Alginate Gel and CaCl with Glutathione 2 ‑Chitosan gel; DATS@CD‑sodium alginate gel and CaCl prepared by the present invention 2 ‑Chitosan gel compound can slow down the reaction between DATS and GSH, realize H 2 For the purpose of sustained release of S, at the same time, the joint application of DATS@CD‑sodium alginate gel and CaCl 2 ‑Chitosan gel can effectively promote diabetic skin wound healing.
