mesaconitine/aconitum

Aconiti tuber, roots of aconite (Aconitum japonicum), has been used for centuries in Japan and China to increase peripheral body temperature. We previously reported that mesaconitine, an alkaloid from Aconitum japonicum, elicits endothelium-dependent and nitric oxide-mediated relaxation in isolated

Mesaconitine, one of Aconitum carmichaelii Debx bioactive compounds, was shown to evoke Ca²⁺ homeostasis and its related physiological effects in endothelial cell types. However, the effect of mesaconitine on Ca²⁺ signaling and cell viability in human brain microvascular

To establish a method for the content determination of indexes for measuring aconitic compounds contained in Shenfu injection, in order to provide basis for the evaluation of the curative effect of monkshood in Shenfu injection. The sample were purified and enriched with HF-LPME. ACQUITY UPLC BEH

Aconiti tuber, roots of aconite (Aconitum japonicum), is an oriental herbal medicine used for centuries in Japan and China to improve the health of persons with a weak constitution and poor metabolism. We investigated the effects of mesaconitine, one of the aconite alkaloids in Aconiti tuber, on the

OBJECTIVE This study was conducted to evaluate the percutaneous absorption of aconitine and mesaconitine in extracts of Radix Aconitum kusnezoffii. METHODS The extracts of Radix Aconitum kusnezoffii were collected by using Franz diffusion cells after permeation through the skin of rats. Then rate

BACKGROUND Aconitum carmichaelii Debx. (Fuzi), a commonly use traditional Chinese medicine (TCM), has often been used in combination with Rhizoma Glycyrrhizae (Gancao) to reduce its toxicity due to diester diterpenoid alkaloids aconitine, mesaconitine, and hypaconitine. However, the mechanism of

1 The effects of mesaconitine, the main alkaloid contained in Aconiti tuber, were investigated by use of extracellular recordings of stimulus-evoked population spikes and field excitatory postsynaptic potentials (e.p.s.ps) in the CA1 region of rat hippocampal slices. 2 At a concentration of 10 nM,

The aim of the present study was to investigate if the plant alkaloid, mesaconitine, which has been reported to have antinociceptive effects via stimulation of the noradrenergic system, inhibits epileptiform field potentials. The experiments were performed as extracellular recordings on rat

The title compound, (1α,3α,6α,14α,15α,16β)-3,8,13,14,15-penta-hydr-oxy-1,6,16-trimeth-oxy-4-methoxy-methyl-20-methyl-acon-itan-8,14-diyl 8-acetate 14-benzoate, C(33)H(45)NO(11), a C(19) diterpenoid alkaloid, obtained from the roots of Aconitum kusnezoffii, has been crystallographically characterized

The Aconitum species (Ranunculaceae) are widely distributed in northern Asia and North America. Their roots are popularly used in herbal medicines in China and Japan. Many cases of accidental, suicidal and homicidal intoxication with this plant have been reported; some of these were fatal because

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

A rapid, specific and precise method using GC/SIM was applied to separate and quantify Aconitum alkaloids in Aconitum tubers. The TMS derivatives of each alkaloid produced a well defined peak on selected ion recording (SIR). Good linear response over the range of 100 pg - 7.5 ng was demonstrated for

In order to find the cardiotonic constituents of lateral roots of Aconitum carmichaelii Debx., the investigation was carried out. Silica gel column chromatography, Sephadex LH-20, medium-pressure MCI and reverse phase ODS column chromatography were used to separate the 90% EtOH extract of the

An ultra performance liquid chromatography (UPLC) method was established and validated to simultaneously determine the contents of six aconitum alkaloids in mother, daughter and fibrous roots of 19 batches of Aconitum carmichaelii from Sichuan province. The separation of the six alkaloids was

The roots of Aconitum carmichaelii Debx. show excellent effects against rheumatism and cardiovascular diseases, but the effective compounds, C19-diester and monoester diterpenoid alkaloids (DDAs and MDAs) are toxic for their narrow therapeutic windows. It is noteworthy to investigate intestinal
