Shikimic Acid in the Leaves of Eucalyptus sieberiana F. Muell.

Shikimic acid was determined in leaves, at different stagesof growth, from 1- and 4-year-old specimens of Eucalyptus sieberianaF. Muell. A linear relationship was found between the shikimicacid concentration (mg./g.) and the weight of the leaf up tothe point where the leaf had reached full size. As the leavesbecame older the shikimic acid content decreased.
