Employing the roots of Iris missouriensis, two known triterpenes, iso-iridogermanal and zeorin, were isolated and identified. As presently reported, they were found to demonstrate cytotoxic activity toward cultured P-388 cells (ED50 = 0.1 and 1.1 microgram/mL, respectively). Additionally, a new triterpene that demonstrated an ED50 of 8.5 micrograms/mL was isolated. On the basis of spectral analysis and chemical correlation with zeorin, the structure was shown to be 6 6 alpha-hydroxy-A'-neogermmacer-22(29)-en-30-oic acid (missourin).
利用密苏里鸢尾的根,分离并鉴定出两种已知的三萜类化合物,异鸢尾醛和玉米苷。如目前所报道的,发现它们对培养的P - 388细胞具有细胞毒性活性(ED50分别为0.1和1.1微克/毫升)。此外,还分离出一种新的三萜类化合物,其ED50为8.5微克/毫升。基于光谱分析以及与玉米苷的化学关联,其结构被确定为6 6α - 羟基 - A' - 新格玛烯 - 22(29) - 烯 - 30 - 酸(密苏里苷)。
