This patent outlines a new method of extraction and application of natural Brassinolide analogs, covering applications to promote plant development, improve plant germination rates, enhance plant resistance to cold temperatures, and salt resistance. Further, the patent lists an agricultural composition, which includes natural Brassinolide analogs.
Brassinolide is recognized around the world as a high-efficient, broad spectrum, nontoxic plant growth regulator, regarded as the sixth plant hormone after auxins, gibberellins, cytokinins, abscisic acid, and ethylene. It features high physiological activity with distinctive functions for plant growth and development, requiring the minimal amount of use. It works with only one-thousandth of the amount needed by any of the other five hormones, making it a very promising option for future applications.
Chengdu Newsun Crop Science Ltd is one of the first enterprises in China to engage in Brassinolide development, production, and promotion. The company is dedicated to researching the technical process of extracting natural Brassinolide from plant material. The patent obtained in the United States protects its latest research findings on Brassinolide, which in the meantime paves the way for the company's product to enter the US market.
