UPLC‐QToF‐MS based fingerprinting of polyphenolic metabolites in the bark extract of Boehmeria rugulosa Wedd

Abstract

Boehmeria rugulosa Wedd. is an evergreen tree of Urticaceae family. Its bark has been extensively used in ethno-medicinal system for various ailments such as bone fracture, sprain, snakebite, and wound healing. Phyto-metabolites, which are considered as the principle components for biological activities, have been least explored for this plant. The present work investigated metabolite profiling of the stem bark of B. rugulosa in water extract using Ultra Performance Liquid Chromatography Quadrupole Time of Flight Mass Spectrometry (UPLC-QToF-MS) technique coupled with the UNIFI platform. We identified, for the first time, 20 polyphenolic metabolites belonging to seven groups: caffeoylquinic acids, coumaroylquinic acids, flavan-3-ols, oligomeric flavonoids, caffeic acid derivatives, coumaric acid derivative, and flavone glycoside in the B. rugulosa extract. UNIFI informatics-coupled UPLC-QToF-MS platform aids in the quick identification and fragmentation pattern of metabolites, with higher degree of reproducibility. The present study provides a chemical and therapeutic basis for further exploration of B. rugulosa as a valuable source of phytochemicals that could be instrumental in deciphering its ethno-medicinal utility for various human diseases.

“…A total of 18 flavonoids were identified. In addition to the removal of hydroxyl groups, methyl groups, methoxy groups and their glycoside moieties, their characteristic fragmentation mainly occurred in the C ring of the flavonoid nucleus in 1, 4 or 0, 3 modes ( 22 ). A total of 21 quinone compounds were identified, and all of them were derived from S. miltiorrhiza .…”
