Abstract

The chemical ingredients of sediments from single Radix Aconiti Lateralis (Fuzi, in Chinese) decoction and Radix Aconiti Lateralis-Radix Glycyrrhizae (Gancao, in Chinese) decoction were evaluated separately by HPLC-MS for exploring their ingredients difference and discussing the mechanism of toxicity reduction of Fuzi-Gaocao herb-pair, even providing the experimental basis for extracting and purifying process of TCM preparations containing Fuzi-Gancao herb-pair. The sediments samples from single Fuzi decoction (FD) and Fuzi-Gaocao decoction (FGD) were prepared separately firstly. Then these samples were analyzed in the same chromatographic and mass spectrometry condition, estimating their HPLC-MS fingerprint and identifying their compounds by Q-TOFMS. As a result, 28 compounds in sediments samples from FD were obtained, among which 25 compounds and structures were confirmed. Besides, 36 compounds in sediments samples from FGD sample were obtained including 34 confirmed compounds and structures, among which there were 11 compounds from Gancao and 25 compounds from Fuzi. However, according to these confirmed compounds, alkaloids compounds in sediments samples from FGD were significantly different from that in sediments samples from FD. This result showed the fact that there would be some influences on alkaloid compounds in decoction after the combination of Gancao. In this study, the experiment basis of the mechanism of toxicity reduction of Fuzi-Gaocao herb-pair is provided. It also showed that much attention should be paid to the fact that there were great amount of alkaloid compounds, the effective compounds, in the sediments for which a comprehensive utilization in clinic and pharmaceutical process should be noted.
