ABSTRACT
OBJECTIVE: To investigate the chemical constituents of Arisaema rhizomatum.
ABSTRACT
Objective: To study the chemical constituents from herb with the roots of Adonis amurensis. Methods: The compounds were isolated and purified by silica gel column, Sephadex LH-20, MCI, and reverse phase HPLC chromatographies, and the structrures of the isolated compounds were elucidated by spectral analysis and physicochemical properties. Results: Fifteen compounds were isolated from EtOAc and n-butanol fraction of the 95% ethanol etract in the herb with the roots of A. amurensis, including seven cardenolides, i.e. strophanthidin (1), convallatoxin (2), convalloside (3), somalin (4), digitoxigenin (5), cymarin (6), and periplorhamnoside (7); five flavonoids, i.e. luteolin (8), apigenin (9), apigenin-7-O-β-D-glucuronide (10), orientin (11), and isoquercitrin (12); and three lignans, i.e. pinoresinol (13), pinoresinol-8-O-β-D-glucopyranoside (14), and 9'-decarboxy rosmarinic acid-4'-O-(1→4)-galactosyl rhamnoside (15). Conclusion: Compounds 10 and 13-15 are firstly isolated from the plants of Adonis L. and compounds 3, 10, and 13-15 are isolated from A. amurensis for the first time.
