Synthesis of 1-Aryl-3-phenethylamino-1-propanone hydrochlorides as possible potent cytotoxic agents.
It was observed that the best mol ratio of the ketone, paraformaldehyde and phenethylamine hydrochloridewas 1:1.2:1 (compared with a 2:2.1 ratio), and the most suitable reaction medium wasethanol containing concentrated hydrochloric acid (comparing with only ethanol or nosolvent).
Iridoid, Flavonoid, and Phenylethanoid Glycosides from Wiedemannia orientalis
Five iridoid glycosides, lamiide, ipolamiide, ipolamiidoside, 6b-hydroxyipolamiide, and 5-hydroxy-8-epi-loganin; 5 flavonoid glycosides, apigenin 7-O-b-glucopyranoside, luteolin 5-O-b-
A New Sulfated α-Ionone Glycoside from Sonchus erzincanicus Matthews
The study describes the isolation and structure elucidation of five flavonoids and two α-ionone glycosides from S. erzincanicus and found corchoionoside C 6’-O-sulfate, isolated for the first time from a natural source, was a new compound.
