A new pyranone, (S)-2-(4-hydroxyphenylethyl)-6-methyl-2,3-dihydro-4H-pyran-4-one, with unusual carbon skeleton, and three new aristolochic acid derivatives (7-O-methylaristolochic acid F, sodium 7-O-methylaristolochate F and sodium aristolochate F) were isolated from Aristolochia urupaensis (Aristolochiaceae) stems together with 31 known compounds. The structures of the compounds were determined by spectroscopic analyses, including Fourier transform infrared (FTIR) and 1D and 2D nuclear… Expand

ARISTOLOCHIC ACID I DETERMINATION IN ARISTOLOCHIA CLEMATITIS L. RAW MATERIALS BY HPLC METHOD
Aristolochia clematitis has long ago been applied in Asian traditional medicine and demonstrates multidirectional pharmacological activity. Contemporary research has confirmed its expressedExpand
Recent developments in detoxication techniques for aristolochic acid-containing traditional Chinese medicines
Aristolochic acids (AAs) have attracted significant attention because they have been proven to be the culprits in the mass incidents of AA nephropathy that occurred in Belgium in 1993. From then on,Expand
A novel and efficient synthesis of phenanthrene derivatives via palladium/norbornadiene-catalyzed domino one-pot reaction
TLDR
A novel palladium-catalyzed reaction that results in phenanthrene derivatives using aryl iodides, ortho-bromobenzoyl chlorides and norbornadiene in one pot has a wider substrate range, shorter reaction times and higher yields of products than previously reported methods. Expand
A Rapidly Method for the Discrimination of Aristolochic Acid and its Analogues Using SVM and PCA
Many traditional Chinese herb medicines containing aristolochic acid (AA) have been implicated in multiple cancer types, especially in upper tract urothelial carcinomas. The detection of AA and itsExpand
1D convolutional neural network for the discrimination of aristolochic acids and their analogues based on near-infrared spectroscopy
TLDR
An end-to-end 1-dimensional convolutional neural network model on the basis of NIRS is developed to distinguish AAs and their analogues in this paper, which extracts feature wavelengths from the original input data instead of using wavelength selection manually. Expand
