A total of 37 commercial samples of paeoniae radix (Paeonia lactiflora Pall. = P. albiflora Pall, and P. vitchii Lynch), were collected from Taiwan's herbal market. The contents of eight constituents (gallic acid, oxypaeoniflorin, albiflorin, paeoniflorin, benzoic acid, pentagalloylglucose, paeonol, and benzyoylalbiflorin) in these samples were determined by high-performance liquid chromatography. It was found that constituent contents in P. lactiflora samples were generally higher than in P. vitchii samples except for the albiflorin/oxypaeoniflorin ratio and paeonol content. The major compounds of P. lactiflora were paeoniflorin, albiflorin, and pentagalloylglucose, while those in P. vitchii were paeoniflorin, pentagalloylglucose, and oxypaeoniflorin. The peak-area ratio of albiflorin/oxypaeoniflorin was higher than unity in P. lactiflora samples but lower than unity in P. vitchii, and the ratio can be used to differentiate the origin of Paeonia species clearly. In addition, the former had higher contents in the core wood but the latter in the cortex. 相似文献

Insights into the neutral loss of 30 Da of Paeonia monoterpene glycosides in electrospray ionization tandem mass spectrometry and the rapid screening of monoterpene glycosides by LC/MS/MS 下载免费PDF全文
Monoterpene glycosides are the major bioactive compounds of Paeonia lactiflora Pall (P. lactiflora). Characteristic neutral loss of 30 Da has been extensively reported for monoterpene glycosides in tandem mass spectrometry. However, little is known about mechanism of this fragmentation. The neutral loss of 30 Da was studied for eleven monoterpene glycosides (1–11) from P. lactiflora by ion trap mass spectrometry in this report. Compounds 1–5 with a hemiacetal structure could readily lose 30 Da at low collision energy of 30% in MS/MS by ion trap mass spectrometry. For compounds 6–11, neutral loss of 30 Da could also be observed at low abundance, but the collision energy had to be increased to 60%. In both cases, high-accuracy mass spectrometry assigned the 30 Da as CH2O. After careful analysis of the structures and mass spectra, we believe that the neutral loss of 30 Da in compounds 1–5 was due to cleavage of the hemiacetal structure, whereas it was ascribed to the cleavage of 5¢-hydroxymethyl group of the glucosyl residue in other monoterpene glycosides. Furthermore, the characteristic neutral loss of 30 Da at low collision energy was used to screen hemiacetals from crude extracts of P. lactiflora and related plant species. Significant differences among Paeonia species were observed by 30 Da neutral loss analysis. 相似文献
