Antimutagenicity of sweetpotato (Ipomoea batatas) roots.
Antimutagenicity of the water extracts prepared from the storage roots of four varieties of sweetpotato with different flesh colors was investigated using Salmonella typhimurium TA 98. The extract from the whole roots of the purple-colored Ayamurasaki variety effectively decreased the reverse mutation induced not only by Trp-P-1, Trp-P-2, IQ, B[a]P, and 4-NQO but also by dimethyl sulfoxide extr...
متن کاملThe hydrolysis of mono-, di-, and triglutamate derivatives of folic acid with bacterial enzymes.
A soil organism of the genus Flavobacterium was isolated from a medium containing folic acid as the sole source of carbon and nitrogen (ATCC 25012). This organism resembles but is not identical with a previously described strain, Flavobacterium polyglutamicum. It utilizes the glutamate released from pteroylmonoglutamate by the action of an intracellular enzyme, folate amidase. The relative rate...

متن کاملSynthesis , Structure , and Spectroscopic Characterization of Unassociated Mono - , Di - , and Triamido Derivatives of Aluminum and Gallium
As part of a study of the possible existence of n-interactions in A1-N or Ga-N bonds, the synthesis and spectroscopic and structural characterization of several unassociated amido derivatives of aluminum and gallium are described. The compounds Mes*GaCl(N(H)Ph}.0.25 (hexane), 1, Mes*zGaN(H)Ph, 2, MesAl(N(SiMe3)2]2, 3, Mes*Ga(NHPh)z, 4, and ClGa{N(SiMe3)2)2, 5 (Mes = 2,4,6-Me&sH2, Mes* = 2,4,6-t...
متن کاملEffect of aqueous extract of Ipomoea carnea leaf on isolated frog and mouse heart.
Ipomoea carnea fam. Convolvulaceae is a poisonous plant and its toxicity is supposed to be due to the cardiac and respiratory failure. The present paper describes the cardiac effect of aqueous extract of the fresh leaves of I. carnea using mouse and frog heart. The aqueous extract produced an initial blockade of isolated frog heart for 5-10 sec followed by dose dependent increase in both amplit...
