Previous research conducted by the Pharmacognosy department
at Oregon State University on Datura tatula indicated that
AMO 1618 and maleic hydrazide (MII) affected the growth and alkaloid
biogenesis of the plant. AMO 1618 treatment increased the
fresh and dry weights of the plants, but decreased the alkaloid
content. MH treatment...
A pharmacognostic study was made of the root of Heracleum
