Influence Alkaloids from the Marine-derived Strain of the Fungus Aspergillus Fumigatus Fresen. on the Growth of Seedling Roots of Buckwheat (fagopyrum Esculentum Moench)

ABSTRACT The effect of alkaloids fumitremorgin С (1), 12,13-dihydroxyfumitremorgin C (2), verruculogen (3), spirotryprostatin А (4), 6-methoxyspirotryprostatin В (5), spirotryprostatin F (6), fumiquinazoline С (7), bisdethiobis(methylthio)gliotoxin (8), and tryptoquivaline F (9) from the marine-derived strain of the fungus Aspergillus fumigatus on the growth of sprout roots of buckwheat at the concentration range 10 -5 -10 -17 M was studied. It was shown that the alkaloids 1, 3, 4, 6, and 7 had a stimulatory effect on the growth of seedling roots of buckwheat. The stimulatory effect of compounds 3, 4, 6, 7 was shown at ultra-low concentration (10 -12 −10 -16 M). The doze–effect curve had a bimodal character.
