Solubility of cycasin
Did you know?
WebCycasin has a solubility of 56.6 gL-1. Given a plentiful supply of water the leaching of toxins from cycads was a rather simple process, yet the time required could vary from a few … WebOral administration results in severe toxicity and greatly reduced urinary excretion of cycasin. Methylazoxymethanol (MAM), the aglycone of cycasin prepared by enzymic hydrolysis of cycasin proved to be toxic when injected. Thus it was demonstrated that the toxic component is the aglycone and not cycasin per se.

Cycads are dioecious plants; there are separate male and female plants. The female plant produces seeds, and the male plant produces cones filled with pollen. The most popular cycad is the sago palm. How much cycasin is in a cycad?
Cycasin is a carcinogenic and neurotoxic glucoside found in cycads such as Cycas revoluta and Zamia pumila. Symptoms of poisoning include vomiting, diarrhea, weakness, seizures, and hepatotoxicity. In metabolic conditions, cycasin is hydrolyzed into glucose and methylazoxymethanol (MAM), the latter of which dissociates into formaldehyde and diazomethane. WebCycasin is metabolized by plant, bacterial, or mammalian β-glucosidases (hydrolysis of β-glycosyl linkage) to liberate the aglycone MAM [92,120]. β-Glucosidases play important roles in diverse aspects of plant physiology including the synthesis and activation of chemical defense compounds (e.g., azoxyglycosides) against herbivores and pathogens [121,122].
