SHIPING c., SHAN S.], TANAKA H. and SHOYAMA Y. Effects of culture temperature on microtuber formation of Aconitum carmichaelii Debx. and aconitine -type alkaloid contents BIOTRONICS 27, 15-20, 1998. The clonally propagated Aconitum carmichaelii Debx. was used for the investigation of microtubering. The rooting condition of propagated shoots affected the establishment of transplantation to soil ...

THE TITLE COMPOUND (SYSTEMATIC NAME 8β-acet-oxy-14α-benzo-yloxy-N-ethyl-13β,15α-dihydr-oxy-1α,6α,16β-trimeth-oxy-4β-methoxy-methyl-eneaconitane), C(34)H(47)NO(10), is a typical aconitine-type C(19)-diterpenoid alkaloid, and was isolated from the roots of the Aconitum carmichaeli Debx. The mol-ecule has an aconitine carbon skeleton with four six-membered rings and two five-membered rings, whose ...

Ten diterpenoid alkaloids, including eight aconitine-type C₁₉-diterpenoid alkaloids and two hetisine-type C₂₀-diterpenoid alkaloids, were isolated from the secondary roots of Aconitum carmichaeli Debx., known as "Fuzi" in Chinese traditional herbal medicine. Their structures were established on the basis of their spectroscopic data and comparison with those of the literature. Among these alkalo...

Despite much research, there remains controversy over the role of gap junctions in seizure processes. Many studies report anticonvulsant effects of gap junction blockade, but contradictory results have also been reported. The aim of this study was to clarify the role of connexin36 (Cx36) gap junctions in neocortical seizures. We used the mouse neocortical slice preparation to investigate the ef...

A rapid and effective method was developed for separation and identification of diester-diterpenoid alkaloids (DDA) in the roots of Aconitum carmichaeli by ultra-high-pressure liquid chromatography coupled with high resolution LTQ-Orbitrap tandem mass spectrometry (UHPLC-LTQ-Orbitrap-MS(n)). According to accurate mass measurement and the characteristic neutral loss filtering strategy, a total o...
