Abstract: A hydrogen sulfide donor in an organic salt form and a preparation method thereof. The hydrogen sulfide donor exists as a salt formed by organic compounds with an alkaline motif and hydrogen sulfide with weak acidity. The hydrogen sulfide donor features with a simple structure, and an easy preparation method. Moreover, hydrogen sulfide donors in different forms can be prepared according to research and development needs. After the hydrogen sulfide donor enters an organism, the process of in vivo dissociation and hydrogen sulfide supply is simple, rapid, and effective, and there is no requirement for enzyme or any other complicated condition, and thus, the hydrogen sulfide donor has a great application prospect and value.
