“…Moreover, previous studies showed that washed cycad flour not only contains significant amounts of cycasin (up to 75 μg/g), but possibly other much larger concentrations of azoxyglycosides (e.g., neocycasins) [45,125]. In reply, Shaw and colleagues noted that l-BMAA was "an unlikely toxin candidate for our rodent model of cycad flour-induced parkinsonism and that a contribution from cycasin and/or MAM could not be ruled out" [252,253].
