BACKGROUND
Aconitum carmichaelii (AC) is a well-known herbal medicine for its excellent pharmacological effects and toxicity. The monoester-diterpenoid alkaloids (MDAs), including benzoylmesaconine (BMC), benzoylaconine (BAC) and benzoylhyaconine (BHC), are the main active components in AC. It was

C19 -diterpenoid alkaloids are the main components of Aconitum duclouxii Levl. The process of separation and purification of these compounds in previous studies was tedious and time consuming, requiring multiple chromatographic steps, thus resulted in low recovery and high cost. In the present work,
