Simultaneous high-performance liquid chromatography with tandem mass spectrometry quantification of six bioactive components in rat plasma after oral administration of Yougui pill.
    Journal of separation science, 2019, Volume: 42, Issue:10

    Yougui pills are a classic Chinese medicine that shows significant effects on nerve regeneration and neuroprotection in modern pharmacological studies. With a complex formula, Yougui pills have faced significant challenges in the fields of bioanalysis and pharmacokinetics in animals and human studies. In the present study, a specific and accurate high-performance liquid chromatography with tandem mass spectrometry method was developed and validated for the quantitative determination of the six bioactive components in rat plasma after oral administration of Yougui pills. Chromatographic separation was performed on a C18 column with a gradient elution system. Samples were analysed using positive ion mode with multiple reaction monitoring mode. The assay showed good linearity for all six bioactive components in the dynamic range of 0.50 to 50 ng/mL with acceptable intra- and inter-batch accuracy and precision. The lower limits of quantification were 0.50 ng/mL for all six bioactive components. The method was successfully applied to rat pharmacokinetics after oral administration of Yougui pills. All six bioactive components were detected in rat plasma, including songorine, benzoylhypaconitine, benzoylmesaconitine, neoline, karacoline, and sweroside, while some other target compounds were not detected, such as rhmannioside A, loganin, and cornuside I. After oral administration of Yougui pills at a dose of 2500 mg/kg, all six bioactive components were rapidly absorbed, resulting in t

Alkaloidal constituents from Aconitum jaluense.
    Archives of pharmacal research, 2003, Volume: 26, Issue:9

    Aconitum jaluense Komar. (Ranunculaceae) is one of the Aconitum plants growing in Korean peninsula. An investigation of the alkaloidal constituents of this species led to the isolation of seven C19-norditerpenoid and a C20-diterpenoid alkaloid. Three of them have been identified as neoline, mesaconitine, and hypaconitine, which were isolated from this plant collected from Mt. Bultasan in the north part. The other five alkaloids were determined as lipomesaconitine, lipohypaconitine, 15alpha-hydroxyneoline, hokbusine A, and napelline, which have not been found in this plant. Structures of those alkaloids were determined on the basis of their spectral data. It is of interest to note that a comparison of the present work and the previous report showed some differences in the alkaloidal contents.
