We have also shown that leaf-diastase, like malt-diastase, cannot 
carry the hydrolysis of the starch beyond the point of maltose; it 
cannot form dextrose. Leaves however contain an enzyme capable 
of inverting cane-sugar. 
We have made a great number of relative determinations of diastase 
in leaves, the results of which are g
