ABSTRACT
To study the variation of six ester-type alkaloids and characteristic fingerprints in the process from Radix Aconite Lateralis to Heishunpian and lay a foundation for the study of the processing principle of Heishunpian, HPLC. analysis was performed on a Phenomenex Gemini C18 (4.6 mm x 250 mm, 5 microm) with acetonitrile and 40 mmol x L(-1) ammonium acetate (adjusted to pH 10 with concentrated ammonia water) as mobile phase. The detection wavelength was set at 235 nm. The flow rate was set at 0.8 mL x min(-1) and the injection volume was 10-20 microL. Six ester-type alkaloids were determined and characteristic fingerprints of the process were established. As the process continues, the contents of diester diterpene alkaloids were decreased step by step, while the contents varia tion of monoester diterpene alkaloids were not obvious. Each sample showed significant difference in characteristic fingerprints. With the exception of 6 known monoester diterpene alkaloids and diester diterpene alkaloids, 13 peaks were marked in the characteristic fingerprints, of which the total change rule of the other 7 unknown peaks were similar with 3 diester diterpene alkaloids. The established method is accurate, reliable and repeatable, and can provide reference for revealing change rule of index components and illuminating processing principle in the process of Heishunpian.
