Dear Joe and others,
Naphtoquinone (C10H6O2) consist of two forms: 1,2 naphtaquinone: This
form is insol. in water and I wonder if it would occur in our plants.
1,4 naphtaquinone: This form can be found in pigments and in vit K.
(I didn't find that this one was poisonous).
Plumbagin (C11H8O3)
The LD50 of plumbagin in mice is 0.015 g/kg! LD50 is
the lethal dosis for 50% of the mice.(here: 0.015 g
plumbagin kills 1 kg mouse...just imagine...)
naphtylisoquinoline alkalo\357ds: I didn't find much
about this, but alkalo\357ds are mostly poisonous.(this
one is a relative of curare, morfine...)
(reference: The Merck index)
I don't know if these compounds are in our CP's, but I
believe J. Schlauer.
The question that I have is: In what quantity do these
compounds occur?
Because it isn't enough for a plant to have
plumbagine, to consider it poisonous! The quantity in
which these compounds occur in the plant is also
important.
Can someone tell me more about this?
Good growing, Hendrik
Belgium
