Regression analysis of marker compound level versus bioactivity.

<p>A regression line comparison (Co-Variance) between the marker compound level and bioactivity of each botanical is shown. A “CONTROL” regression line representing a 1:1 cause and effect relationship is shown for comparison. The p-value representing the statistical difference between the marker compound level and bioactivity is shown.</p

Marker compound level and bioactivity of antifungal herbs.

<p>Part A) Marker compound level (percent of total weight) of courmarin (from <i>C</i>. <i>burmanii)</i> and piperine (from <i>P</i>. <i>cubeba)</i> and <i>Candida albcians</i> hyphal growth ID₅₀ values (microliters/ml) are shown from three commercial sources. Part B) Marker compound ratios and bioactivity ratios were normalized to 100 (max. level) and graphed.</p

Marker compound level and bioactivity of antiviral herbs.

<p>Part A) Marker compound level (percent of total weight) of glycyrrhizic acid (from <i>G</i>. <i>glabra)</i> and hyperforin (from <i>H</i>. <i>perforatum)</i> and HSV-1 ID₅₀ values (μl/ml) are shown from three commercial sources. Part B) Marker compound ratios and bioactivity ratios were normalized to 100 (max. level) and graphed.</p

Marker compound level and bioactivity of immune-stimulatory herbs.

<p>Part A) Marker compound level (percent of total weight) of cafteric acid, echinacoside and cichoric acid (from <i>E</i>. <i>purpurea)</i> and astragaloside I (from <i>A</i>. <i>membranaceus)</i> and cytokine induction values (relative to untreated) are shown from three commercial sources. Part B) Marker compound ratios and bioactivity ratios were normalized to 100 (max. level) and graphed.</p

Marker compound level and bioactivity of antibacterial herbs.

<p>Part A) Marker compound level (percent of total weight) of eucalyptol (from <i>E</i>. <i>globulus)</i> and arbutin (from <i>T</i>. <i>diffusa)</i> and <i>Staphylococcus aureus</i> MIC values (microliters/ml) are shown from three commercial sources. Part B) Marker compound ratios and bioactivity ratios were normalized to 100 (max. level) and graphed.</p
