油菜素内酯又叫481,是一种新型甾醇类植物生长调节剂。1988年我国成都生物激素研究所以独特的工艺从天然物中用提取法生产油菜素内酯获得成功。 油菜素内酯主要生理特征表现在:增强植物叶片内超氧物歧化酶(SOD)的活性;促进植物组织分泌;减少细胞膜透性,保护膜的完整性;有效调 Brassinolide, also known as 481, is a novel steroid plant growth regulator. In 1988, our institute of bio-hormones in Chengdu in our country succeeded in the production of brassinolide from the natural products by the unique process. The main physiological characteristics of brassinolide are as follows: enhancing the activity of superoxide dismutase (SOD) in plant leaves; promoting the secretion of plant tissues; reducing the permeability of the cell membrane and protecting the integrity of the membrane;
