其他名称：芸苔素内酯；八仙丰产素；(22R，23R,24R)-2α,3α,22,23-四羟基-24甲基-5α-胆甾-6-酮
CAS号：78821-43-9
C28H48O6=480.68
级别：High Purity Grade
含量：≥98.0%
熔点：256～258℃
干燥失重：≤0.7%
性状：白色结晶粉末。可溶于甲醇、乙醇、四氢呋喃、丙酮等有机溶剂。水中溶解度5mg/L。毒性LD50(mg/kg)：大白鼠急性经口大于2000原药/kg，小白鼠急性经口大于1000mg原药/kg。Ames试验表明无致突变作用
用途：生化研究。低毒作物生长调节剂。在低浓度下（10-5～10-6mg/L）能显示各种活性，其增加植物的营养体生长和促进受精的作用。现已从几十种植物体中分离出这类化合物，含量很低，如植物体中含有吲哚乙酸（IAA）和脱落酸（ABA）分别约为2mg/kg和60mg/kg，而芸苔素内酯仅0.1mg/kg。 用0.05～0.5mg/L芸苔素内酯对小麦浸种24h，促进根系和株高生长发育；分蘖期进行叶片施肥，增加分蘖数；也可在孕穗期以0.01～0.02、0.01～0.02（750L/ha次）、0.01～0.04mg/L（750L/ha次）药液喷雾处理或浸种
