Monoglycerides, diglycerides, triglycerides와 free fatty acids를 대상으로 brassinosteroid검정용 생물검정법인 rice inclination test에 의해 생물활성을 검정하였다. Monoglycerides 뿐만 아니라 diglycerides, triglycerides 그리고 free fatty acids의 일부도 이 생물검정법에 양성을 나타냈다. 활성을 나타낸 물질중 ${alpha}$-monoolein, diolein은 동일 농도의 indole-3-acetic acid 보다 높은 생물활성을 나타내어 olein 관련물질이 특히 높은 생물활성을 갖는 흥미로운 사실을 확인할 수 있었다.
The biological activity of monoglycerides, diglycerides, triglycerides and free fatty acids were investigated by the rice inclination test that is specific bioassay for brassinosteroids. The experimental results revealed that some diglycerides, triglycerides and free fatty acids as well as monoglycerides showed positive response. ${alpha}-Monoolein$ and diolein as active principles showed higher activity than indole-3-acetic acid at the same concentration. From the results, it can be confirmed that the active principles are related to olein which especially have a high activity.
