BACKGROUND
The crude secondary roots of Aconitum carmichaelii Debeaux (Fuzi), together with its processed products, including Yanfuzi, Heishunpian and Paofupian, are commonly applied in clinic using for thousands of years, such as collapse, syncope, rheumatic fever, painful joints and various tumors.
OBJECTIVE
To explore the different effects of Fuzi and its processed products on energy metabolism, with mitochondria as the model with the aim of guiding the clinical use of Fuzi and its products. fingerprints of Fuzi, Yanfuzi, Heishunpian and Paofupian were established by Ultra-high Performance Liquid Chromatography (UPLC) and effects of Fuzi and its processed products on rat's liver׳s mitochondrial metabolism were studied by microcalorimetry. Spectrum-effect relationships between UPLC fingerprints and energy metabolism of mitochondria were investigated using canonical correlation analysis (CCA).
RESULTS
Because of their inherent differences in chemical compositions, the main activities of energy metabolism of mitochondria were different among Fuzi and its processed products. The potential bioactivity sequence of the tested products was Fuzi>Heishunpian>Paofupian>Yanfuzi. RESULTS of CCA showed that compounds mesaconitine, benzoylaconitine, and benzoylhypacoitine might be the principal active components.
CONCLUSIONS
Altogether, this work provides a general model of combination of UPLC and microcalorimetry to study the spectrum-effect relationships of Fuzi and its processed products which can offer some references for detecting principal components of traditional Chinese medicine on bioactivity to mitochondrial growth.
