Figure 3. Comparison of alkylamide yield in fresh 1:2, dry 1:11 and dry 1:5 E. purpurea root ethanolic extracts.

Figure 3

All concentrations represent the mean from four replicate extractions at room temperature. Error bars denote standard error of the mean (SEM). Comparisons were made between Fresh 1:2, Dry 1:11 and 1:5 extracts, with * indicating p<0.005; ** indicating p<0.001. Alkylamide yield is similar in the fresh 1:2 and dry 1:11 extracts, indicating no loss of alkylamides in the drying process. Better yield of alkylamide J was obtained for the fresh 1:2 versus dry 1:11 extract.
