Chemical constituents of Aconitum brachypodum from Dong-Chuan area / 中国中药杂志

ABSTRACT

Aconitum brachypodum is traditionally known to be toxic chinese medicie, but its chemical constituents is not enough studied to date. To further elucidate the chemical constituents of A. brachypodum, 80% ethanol extract of A. brachypodum collected from Dong-Chuan area was investigated, which led to isolation of seventeen compounds. By spectroscopic methods, their structures were determined as hypaconitine (1), mesaconitine (2), talatisamine (3), neoline (4), fuziline (5), aconine (6), bullatine A (7), lepeine (8), songrine (9), isocorydine (10), beta-sitosterol (11), daucosterol (12), stearic acid (13), triacontanol (14), palmitic acid (15), benzoic acid (16), and inosine (17), respectively. All compounds except for compounds 1 and 7 were isolated from A. brachypodum for the first time.
