aconine/aconitum

The chemical components in the decoctions of Chinese herbal medicines are not always the same as those in the crude herbs because of the insolubility or instability of some compounds. In this work, a high-performance liquid chromatography (HPLC) coupled with electrospray ionization (ESI) tandem mass

An efficient and refined method for the separation of six aconitine-type alkaloids from the alkaline prepared "Kusnezoff monkshood root" was extablished. It is the first study that two new lipo-alkaloids were successfully isolated from refined sample by pH-zone-refining counter-current

Aconitum brachypodum is traditionally known to be toxic chinese medicie, but its chemical constituents is not enough studied to date. To further elucidate the chemical constituents of A. brachypodum, 80% ethanol extract of A. brachypodum collected from Dong-Chuan area was investigated, which led to

A rapid, convenient and effective identification method of alkaloids was established and an attempt on isolating and analyzing the alkaloids in Aconitum pendulum Busch was conducted successfully. In this article, four high-content components including deoxyaconitine, benzoylaconine, aconine and

BACKGROUND Crude radix Aconitum kusnezoffii (RAK) has great toxicity. Traditional Chinese medicine practice proved that processing may decrease its toxicity. In our previous study, we had established a new method of RAK processing (Paozhi). However, the mechanism is yet not perfect. OBJECTIVE To

OBJECTIVE Aconitum carmichaelii Debx. (Fuzi) is usually compatible with Rheum palmatum L. (Dahuang) in clinic. The study is conducted to investigate the influence of Dahuang on the pharmacokinetics of Fuzi. METHODS Twelve rats were randomly divided into two groups. Fuzi group was orally administered

OBJECTIVE To study the processing principles of different processed products of Aconitum pendulum. METHODS Using high performance liquid chromatography and acute toxicity test to compare the changes in chemical composition and toxicity of the roots and processed products of A. pendulum. RESULTS The

Diterpenoid alkaloids with remarkable chemical properties and biological activities are frequently found in plants of the genera Aconitum, Delphinium, and Garrya. Accordingly, several diterpenoid alkaloid constituents of Aconitum and Delphinium plants as well as their derivatives exhibited cytotoxic

The stability of diester-diterpenoid alkaloids (DDA) from plants of the genus Aconitum L. has been studied in different solvents and pH buffers. The HPLC/ESIMS method for analysing the concentration of DDA was established and DDA's decomposition products were elucidated by HPLC/ESI-MS/MS(n). In

The Aconitum species, which mainly contain bioactive Aconitum alkaloids, are frequently administered concomitantly with other herbal medicines or chemical drugs in clinics. The potential risk of drug-drug interactions (DDIs) arising from co-administration of Aconitum alkaloids and other drugs

OBJECTIVE To study the change of chemical compound after decocting the flowers of Aconitum kusnzoffii Reichb (FAK) by analyzing the alkaloids in FAK and the decoction of FAK qualitatively. METHODS The alkaloid extracts of FAK and alkaloid mixtures in the decoction of FAK were directly analyzed by

Determination of fourteen alkaloids, toxic Aconitum alkaloids, aconitine, mesaconitine, jesaconitine, hypaconitine and deoxyaconitine, and their hydrolysis products, benzoylaconines and aconines, have been established using capillary liquid chromatography (LC) fast atom bombardment mass spectrometry

Aconitines, including bulleyaconitine A, probably the most bioactive and abundant alkaloids in Aconitum plant, are a group of diester C19-diterpenoid alkaloids with one acetylester group attached to C8 of the diterpenoid skeleton and one benzoylester group to C14. Hydrolysis of both groups is

A convenient and accurate high-performance liquid chromatography coupled with evaporative light scattering detection (HPLC-ELSD) method using solid phase extraction (SPE) was established for quantification of five aminoalcohol-diterpenoid alkaloids (ADAs), including mesaconine, aconine, hypaconine,

OBJECTIVE Aconitum alkaloids mainly contain highly toxic aconitine (AC), mesaconitine (MA), and hypaconitine (HA) and less toxic benzoylaconine (BAC), benzoylmesaconine (BMA), benzoylhypaconine (BHA), aconine, mesaconine, and hypaconine. The efflux transporters including P-glycoprotein (P-gp),
