From: Does patchouli oil change blood platelet monoamine oxidase-A activity of adult mammals?
A Effect of various concentrations of serotonin (0.05–0.4 mM) on blood platelet MAO-A activity in control and short-term single patchouli oil-exposed rats. Results are expressed as mean ± SEM of 4–6 separate observations. Each observation was made from a single rat. The filled circle represents the control, the filled diamond represents five drops patchouli oil of 1-h single exposure, and the filled triangle represents ten drops patchouli oil of 4-h single exposure. Other details are the same as were described in the legend of Fig. 3. B Lineweaver–Burk plot of blood platelet MAO-A activity in control and short-term patchouli oil-exposed rats. Lineweaver–Burk plot was drawn from the progress curve with varying substrate concentration as presented in A
