Structural Similarity in Natural Products Leading to Sample Misidentification: A Case Study of the Bisbenzylisoquinoline Alkaloids Oxyacanthine and Berbamine.

The similar structures of natural compounds and the absence of NMR data for commercial products raise the risk of misidentification. This work reports a case in which purchased samples labeled as "berbamine" from 14 suppliers are oxyacanthine (). The NMR data of all purchased samples were consistent.

Discrimination of the Essential Oils Obtained from Four Apiaceae Species Using Multivariate Analysis Based on the Chemical Compositions and Their Biological Activity.

The chemical composition of the essential oils obtained from the aerial parts of four Apiaceae species, namely (EA), (EP), (FC), and (HI), were determined using gas chromatography. Altogether, 100 volatile metabolites representing 78.97, 81.

Sugar Containing Compounds and Biological Activities of .

Phytochemical investigation of the methanolic extract obtained from the aerial parts of (Lamiaceae) afforded the new compound 1-methoxy-3---glucopyranosyl-α-l-oliose () together with five known glycosides, namely sitosterol-3---glucoside (), stigmasterol-3---glucoside (), pinitol (), 6-hydroxyl-7--loganin (), and chlorotuberoside (). The structures of these compounds were elucidated by extensive spectroscopic analyses, especially HR-MS, 1D and 2D NMR spectroscopy. The in vitro cytotoxic activity of the methanolic extract and the isolated compounds was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) and crystal violet (CV) staining assays.
