The aim of this study was to investigate the effect of Fritillariae Cirrhosae Bulbus, Fritillariae Thunbergii Bulbus, Pinelliae Rhizoma in different ratios with Wu-tou decoction （2：1, 1：1, 1：2） by measuring the therapeutic effects in Wu-tou decoction of main seven alkaloids including benzoylaconitine （BA）, benzoylmesaconitine （BM）, benzoylhypaconitine （BH）, hypaconitine （HA）, fuziline （FU）, niaolin （NE） and deoxyaconitine （DA）. The permeability of aconitum alkaloids extract through a Caco-2 cell monolayer was analyzed in the absence and presence of Fritillariae Cirrhosae Bulbus, Fritillariae Thunbergii Bulbus, and Pinelliae Rhizoma, respectively. The results showed that Pinelliae Rhizoma could reduce the absorption of the alkaloids and increase the excretion of the alkaloids, which would attenuate the therapeutic effects of Wu-tou decoction. Therefore, Pinelliae Rhizoma is an incompatible herb of Wu-tou decoction because of the inhibition of the absorption of alkaloids in the intestine. And that Fritillariae Cirrhosae Bulbus and Fritillariae rhunbergii Bulbus showed the effects to improve the permeability of the alkaloids in Wu-tou decoction. These effects of these two herbs were similar, but the former was stronger than the latter, which most likely is due to the fact that the compositions of these two traditional Chinese medicines are similar. The in vitro data suggests that the compounds such as fritillary presented in alkaloids in the formula maybe improve the therapeutic function caused by the increased bioavailability of alkaloids in intestine.展开更多

In this study, Caco-2 cell monolayer model was used to study compatibility of the transport of the Veratrum alkaloids in different proportions with Panax ginseng. A specific ultra-high performance liquid chromatographic-electrospray ionization-mass spectrometric（UPLC-ESI-MS） method is developed for the semi-quantitative determination of Veratrum alkaloids on intestinal transport with berberine as internal standard（IS）. In the Caco-2 model constructed, three influencing factors are investigated, including time, concentration and recovery rates of the Veratrum alkaloids during the uptake from AP（apical side） to BL（basolateral side）. The results suggest that the flux of Veratrum alkaloids is time dependent and concentration dependent. And the absorption of all eight Veratrum alkaloids increase after compatibility with Panax ginseng compared to the single Veratrum nigrum extraction. This research was studied from the perspective of intestinal absorption by the UPLCESI-MS method. This method was successfully applied to transport studies of the Veratrum alkaloids and the interaction mechanism between Veratrum nigrum and Panax ginseng.展开更多
