PENG Shao, LIU Li-ping, JIN Yong-ri, et al. Determination of Songorine in Aconiti Kusnezoffii Radix by RP-HPLC-ELSD[J]. Chinese journal of experimental traditional medical formulae, 2016, 22(11): 80-83. DOI: 10.13422/j.cnki.syfjx.2016110080.
Objective: To establish a method for determining the content of songorine (a kind of diterpenoid alkaloids) in Aconiti Kusnezoffii Radix. Method: RP-HPLC was carried out on an Agilent Extend-C18(4.6 mm×250 mm
5 μm) with acetonitrile-0.1% triethylamine solution (40: 60) as the mobile phase at a flow rate of 1.0 mL·min-1 and column temperature of 25℃. The drift tube temperature of ELSD was set at 96℃
with the gas (air) pressure of 2.50 bar
and the impactor was in a closed status. Result: The songorine showed good linear relationship in the range of 1.5-30 μg (r=0.999 5). Its average recovery rate was 96.86% with RSD of 1.7%. Conclusion: This established method is simple
quick and accurate
which can be used to determine the content of songorine in Aconiti Kusnezoffii Radix and provide reference for quality evaluation of Aconiti Kusnezoffii Radix.
