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
mantegazzianum, an umbelliferous species which is of value as a
source of natural coumarins.
Three groups of seeds were tested to determine the presence
of a germination requirement for moist cold and the possible value
of gibberellic acid in obviating...
There are numerous references in the literature concerning
the use of various Arctostaphylos species as medicinal plants.
One of the species, A. uva-ursi, was listed in the United States
official compendia from 1820 until 1946 as a urinary antiseptic.
Many species indigenous to the Pacific Northwest were employed
by the...
In view of the stimulant effects of gibberellic acid on plant
growth, and its interesting modifications of various metabolic products,
it was decided to determine whether this growth regulator
would induce a favorable effect on total alkaloid production, especially
on the antineoplastic alkaloids, of Catharanthus roseus (L.) G. Don
(Vinca...
