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
Hypaconitine (HC) is one of the main aconitum alkaloids in Aconitum carmichaelii (AC), which is considered to be effective on cardiovascular disease, although it also has high toxicity. Sini Decoction (SND), composed of Aconitum carmichaelii, Glycyrrhiza uralensis and Zingiber officinale, is a
In this paper, the contents of hypaconitine in the roots of Aconitum coreanum and its processed products were determined by high performance liquid chromatography. The result provides scientific basis for processing the roots of Aconitum coreanum.
Hypaconitine is an active component of Aconitum carmichaelii Debx, a Chinese medicinal herb for the treatment of cardiovascular diseases, but the mechanism underlying its effect remains elusive. In this study, we found that hypaconitine, rather than aconitum alkaloids in A. carmichaelii (e.g.
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
Hypaconitine (HA), an active and highly toxic constituent derived from Aconitum species, is widely used to treat rheumatism. Little is known about the hepatic cytochrome P450-catalyzed metabolism of HA. The present study investigated the metabolism of HA in vitro using male human liver microsomes
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
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
Amino alcohol alkaloids are the active components in the lateral root of Aconitum carmichaelii Debx. (Fuzi), and they have a variety of pharmacological activities. However, the chemical fingerprints of the ester alkaloids reported to date were mainly obtained from high-performance liquid
Aconitum jaluense Komar. (Ranunculaceae) is one of the Aconitum plants growing in Korean peninsula. An investigation of the alkaloidal constituents of this species led to the isolation of seven C19-norditerpenoid and a C20-diterpenoid alkaloid. Three of them have been identified as neoline,
Despite their well-known toxicity, Aconitum species are important traditional medicines worldwide. Aconitum carmichaelii, known in Chinese as (fuzi), is an officially recognized traditional Chinese medicine with characteristic analgesic and anti-inflammatory activities, whose principal
BACKGROUND
Aconitum carmichaelii Debx. (Fuzi in Chinese) has been widely clinically used to treat heart failure and rheumatism. Whereas its serious toxicity, Radix et Rhizoma Glycyrrhizae (Gancao in Chinese) was combined with it as traditional Chinese medicine (TCM) herb-pair for toxicity reduction
BACKGROUND
In traditional Chinese medicine, processed aconite root (lateral root of Aconitum carmichaelii Debx.) is used as the principle herb of the Si-Ni decoction (SND) formula due to its cardiotonic effect, while its cardiotoxicity and neurotoxicity caused by diester and monoester diterpenoid
In the present study, an ultra performance liquid chromatography coupled with time-of-flight mass spectrometry (UPLC/Q-TOFMS) based on chemical profiling approach to evaluate chemical constitution between mixed decoction and co-decoction of monkshood-pinellia combination of the eighteen incompatible
