OBJECTIVE
To study and approach the processing methods and mechanism which can markedly reduce the content of aristolochic acid in Aristolochia manshuriensis and lighten the nephrotoxicity of aristolochic acid.
METHODS
A traditional "attenuation" processing method was used and 30 types of samples
OBJECTIVE
To develop a HPLC method to determine the contents of aristolochic A in aristolochia debilis and Asarun spp..
METHODS
Methanol-water-formic acid extracts were separated on an Alltech C18 column with methanol-water-acetic acid (68:32:1) as mobile phase. The flow rate was 1.0 mL x min(-1).
OBJECTIVE
To explore the hypothesis that chronic dietary poisoning by aristolochic acid could account for the unique geographical distribution, specific pattern of tubulointerstitial fibrosis, occurrence of chronic renal insufficiency, and an increased risk of developing upper urothelial cancer, all
OBJECTIVE
The acute toxic effects of Aristolochia manshuriensis (GMT) and the total aristolochic acids (TA) were compared in mice with aristolochic acid A (AA) as the dose standard. The dose relationship of the renal toxicity induced by Aristolochia manshuriensis was determined.
METHODS
A single
The medicinal use of Aristolochia clematitis has been known for some time. The main active agent of this medicinal plant is aristolochic acid, a nitrophenanthrenecarbonic acid. Very recently, however, the Federal Health Office withdrew the licence for all drugs containing aristolochic acid, because
Aristolochia species have been administered by those trained in traditional Chinese medicine (TCM) for centuries. After determining Aristolochia fangchi was an adulterant that caused death due to renal failure in a number of patients at a Belgian weight loss clinic, many countries took steps to
Stephania tetrandra ("hang fang ji") and Aristolochia fangchi ("guang fang ji") are two different plant species used in Traditional Chinese Medicine (TCM). Both are commonly referred to as "fang ji" and S. tetrandra is mistakenly substituted and adulterated with the nephrotoxic A. fangchi as they
