Brief history of natural brassinolide:

Natural brassinolide (or Brassinosteroids, BRs) are a class of polyhydroxysteroids that have been recognized as a sixth class of plant hormones. These were first explored nearly 40 years ago, when promotion was reported in stem elongation and cell division by the treatment of organic extracts of rapeseed (Brassica napus) pollen.

 

Chengdu Newsun began the research on Brassinosteroids in 1985. It successfully isolated six most active compounds from Brassinosteroids, and realized commercial production. Now it has been the largest manufacturer and exporter of natural brassinolide technical and formulation products in China.
