To identify the products of hypaconitine in
water and methanol, electrospray ionization mass
spectrometry (ESI-MS) method is used to trigger
a full scan product ion experiment for
confirmation. Six hydrolysates were detected,
and their pseudo-molecules are 470, 556, 574,
484, 452 and 588, respectively, indicating
hypaconine, pyrhypaconitine, benzoylhypaconine,
8-methoxyl-hypaconine, dehydration hypaconine
respectively. Among them, 8-methoxyl-hypaconine,
8-methoxyl-14-benzoyl-hypaconine and dehydration
hypaconine are identified first in the reaction
products of hypaconitine in methanol.
