Abstract

A component $F,\;C_{20}H_{30}O_4,\;M^+\;(m/e)\;334,\;mp\;258{\sim}260^{\circ},\;[{\alpha}]D=-133.25^{\circ}\;(C=0.2,\;EtOH)$, was isolated from Siegesbeckia pubescens $M_{AKINO}$. This compound was identified as $16{\beta}-(-)-kauran-17$, 19-dioic acid, using spectroscopies and synthesizing various derivatives of the compound F.
