Abstract
The principal alkaloid of Cynoglossum
latifolium R.Br. is latifoline, C20H27O7N, an
ester of 7-angelylretronecine with the γ-lactone of
3,4-dihydroxypentane-2,3-dicarboxylic acid. 7-Angelylretronecine, itself,
occurs as a minor constituent. Both alkaloids are subject to substantial
decomposition during drying of the plant and 7-angelylretronecine may be formed
by enzymatic attack on latifoline.
