用自制ＭＡＡ荧光试剂，对兔体中苦参碱和氧化苦参碱进行２４ｈ监测，检出限分别为１．４１×１０－１１ｇ／ｍＬ和４．５×１０－１２ｇ／ｍＬ，血中苦参碱和氧化苦参碱的浓度在１０－９～１０－８ｇ／ｍＬ之间，该法快速、灵敏、效果良好．
The MAA fluorescent reagent was used to monitor the matrine and oxymatrine in rabbits for 24 hours. The detection limits were 1.41 × 10-11g / mL and 4.5 × 10-12g / mL respectively. The concentration of caffeine and oxymatrine is between 10-9 and 10-8g / mL. The method is fast, sensitive and effective.
