ABSTRACT
Objective To study the solubility of lipo-alkaloids from prepared aconite root(Radix Aconiti Lateralis Preparata) and identify the sources of lipo-alkaloids in Sini Decoction.Methods The electrospray ionization mass spectrometry was employed to analyze the alkaloids in crude aconite roots,Sini Decoction,the gruffs of concocted aconite roots and the decoction of prepared aconite root and pinellia tuber(Rhizoma Pinellae).Results Lipo-alkaloids were observed in Sini Decoction,however,no lipo-(alkaloids) were found in the decoction of aconite roots with pinellia tuber.Lipo-alkaloids were the dominant components in the gruffs of concocted aconite roots.Conclusion Lipo-alkaloids are barely soluble in boiling water.The alkaloids existed in the Sini Decoction stem from the ester-exchange reactions of diester-diterpenoid alkaloids and fatty acid in the boiling water.
ABSTRACT
AIM:To study the bioactive components effect of every kind of herbal in Naru Sanwei Pill (Fructus litseae, Fructus chebulae) on Radix Aconiti kusnezoffii. METHODS: Analysising the Naru Sanwei Pill, adding the extraction of Radix Aconiti kusnezoffii to Fructus chebulae and Fructus litseae and was analyzed by ESI-MS~n. RESULTS: The quantity of mesaconitin was low in the extraction of Aconitum kusnezoffii Reichb,and Fructus chebulae.Long Pepper did not have much effect on alkaloids of Aconiti kusnezoffii Reichb. CONCLUSION: Fructus chebulae reduced toxicity in the process of Radix aconiti kusnezoffii,through lowering the dissolving-out of aconitine.
