Abstract

A biologically monitored fractionation of the resinous exudate extract of Haplopappus foliosus DC. is reported. Purification of the two active fractions yielded 2-α-hydroxy-cis-cleroda-3,13(Z),8(17)-trien-15-oic acid (1) and 2-α-acetoxy-cis-cleroda-3,13(Z),8(17)-trien-15-oic acid (2), two new clerodane diterpenes.
