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 μg/mL, respectively). Additionally, a new triterpene that demonstrated an ED50 of 8.5 μg/mL was isolated. On the basis of spectral analysis and chemical correlation with zeorin, the structure was shown to be 6α‐hydroxy‐A'‐neogermmacer‐22(29)‐en‐30‐oic acid (missourin).
