从栽培玫瑰花的乙醇提取物中分离出一种结晶形式的细胞分裂因子。冠瘿瘤组织。该结晶物质显示出核糖基-反式-玉米素，即6-（4-羟基-3-甲基-反式-2-丁烯基氨基）-9-β-D-呋喃核糖基嘌呤的熔点、质谱、紫外光吸收光谱、溶解度、色谱迁移值、离子交换行为和预期的生长活性。这种化合物似乎是提取物中的主要细胞分裂因子，也从肿瘤组织生长的液体培养基中结晶出来，显然是这种培养基中唯一的活性化合物。
A cell division factor in crystalline form has been isolated from ethanolic extracts of cultured Vinca rosea L. crown gall tumor tissue. The crystalline material shows the melting point, mass spectrum, ultraviolet-light absorbancy spectra, solubilities, chromatographic migration values, ion-exchange behavior, and growth activities expected of ribosyl-trans-zeatin, that is, 6-(4-hydroxyl-3-methyl-trans-2-butenylamino)-9-beta-D- ribofuranosylpurine. This compound, which appears to be a major cell-division factor in the extracts, has also been crystallized from liquid media in which the tumor tissue had been growing and apparently was the only active compound in such media.
