  • Red Maple Toxicosis
    potentially fatal methemoglobinemia Gallic acid and tannins from A rubrum leaves have been implicated as the toxic compounds responsible for Red Maple Toxicosis Boyer et al 2002 but this study found that pyrogallol is a more potent inducer of methemoglobinemia Figure 1 Results of the incubation of simple phenolics with equine blood samples at 37 C for 3 hours Dark color is indicative of methemoglobin formation Key A Tannic Acid 200 g mL B Gallic Acid 200 g mL C Pyrogallol 25 g mL D Pyrogallol 50 g mL E Pyrogallol 100 g mL F Pyrogallol 200 g mL G Catechol 200 g mL H Ferulic Acid 200 g mL I p Coumaric Acid 200 g mL J trans Cinnamic Acid 200 g mL K Control blood sample Hypothesis Objectives Given that the conversion of gallic acid to pyrogallol involves a decarboxylation reaction and the literature suggests a microbial basis for the metabolism of tannins to gallic acid and subsequent pyrogallol production it is hypothesized that the hydrolysable tannins and free gallic acid in in A rubrum leaves are protoxic and undergo metabolism to the oxidative agent pyrogallol as outlined above The objective of this study is to isolate and identify compounds in A rubrum capable of inducing toxicosis in equids and elucidate their mechanism of action Results Gallic acid was metabolized to pyrogallol most consistently in the equine ileum in the first 24 hours Incubation of tannic acid with ileum contents produced gallic acid and subsequently pyrogallol The same pathway was observed using A rubrum leaves Unfiltered suspensions of ileum incubated with gallic acid demonstrated pyrogallol formation but filtered suspensions did not suggesting a microbial metabolic pathway Bacteria isolated from the ileum capable of forming pyrogallol from maple leaves were identified as Klebsiella pneumoniae and Enterobacter cloacae Figure 2
