Steroidal alkaloids of Veratrum lobelianum Bernh. and Veratrum nigrum L.
Twelve steroidal alkaloids were isolated from four populations of Veratrum lobelianum Bernh. and Veratrum nigrum L. Full NMR data for veralosinine (1), and extensive 1H NMR data for veralosine (3) and teinemine (5) are presented here for the first time. (+/-)-15-O-(2-Methylbutyroyl)germine (10) is undescribed up to now. The antiproliferative activities of veranigrine, veralosinine, and neogermi...

متن کاملSteroidal alkaloids from Veratrum taliense
Phytochemical reinvestigation of the roots and rhizomes of Veratrum taliense yield three known (solanidine, veramiline-3-0-~D-glucopyranoside and stenophylline B-3-0-~D-glucopyranoside) and two novel steroidal alkaloids. The structures of the new compounds have been established by a combination of spectroscopic methods as 3angeloylzygadenine-I3-N-oxide and (20S,25S)-22,26-epiminocholesta-5,22-d...

متن کاملAlkaloids from Veratrum album subsp. lobelianum
I n our preceding paper [1] we reported t h e isolation of a novel, amorphous ester alkaloid from Veratrum album subsp. lobelianum (BERNH.) Suessenguth. This al kaloid has been found, together with protoveratrine A, germitetrine and veratroylzygadenine in the ester alkaloid fraction [2]. Acetylveratroylgermine designated originally amorphous alkaloid [1] [a]f) + 6 . 6 ° (chloroform) has, accor...
