应用生物活性鉴定技术、TLC及化学成分检验法，论证了苦楝果实中含有对植物生长促进的活性物质，并初步证明这些活性物质为极性较大的萜类化合物，笔者将这些活性物质称为“苦楝生长素类”。 The bioactive identification techniques, TLC and chemical composition test were used to demonstrate that the fruits of Melia azedarach contained active substances for plant growth promotion. The active compounds were primarily proved to be terpenoids with higher polarities. The authors described these active substances as “Flesh Melin auxin class.”
