Analysis of isoquinoline alkaloids from Mahonia leschenaultia and Mahonia napaulensis roots using UHPLC-Orbitrap-MSn and UHPLC-QqQLIT-MS/MS
Mahonia leschenaultia (ML) and Mahonia napaulensis (MN) are less known and unexplored medicinal plants of the family Berberidaceae. They are used by the Todas of Nilgiris in their religious and medical practices but chemically less identified. Hence, we decided to do extensive phytochemical analysis to explore the potential of these plant extracts. An ultrahigh performance electrospray tandem m...
متن کاملChemical profiling analysis of Maca using UHPLC-ESI-Orbitrap MS coupled with UHPLC-ESI-QqQ MS and the neuroprotective study on its active ingredients
Lepidium meyenii (Maca), originated from Peru, has been cultivated widely in China as a popular health care food. However, the chemical and effective studies of Maca were less in-depth, which restricted its application seriously. To ensure the quality of Maca, a feasible and accurate strategy was established. One hundred and sixty compounds including 30 reference standards were identified in 6 ...
متن کاملIsolation of quaternary alkaloids from Mahonia aquifotium
Five alkaloids were isolated from the underground part of Mahonia aquifolium of domestic origin: magnoflorine, berberine, palmatine, jatrorrhizine, and columbamine. The aerial part of this plant contained only berberine, palmati ne, and jatrorrhizine. The identity of the isolated bases was corroborated by colour reactions in the u.v. light, by i.r. and mass spectra, optical rotation and compar...
متن کاملTertiary alkaloids of Mahonia aquifolium
The bisbenzylisoquinoline alkaloids aromoline and obamegine and the protoberberine alkaloid oxyberberine were isolated for the first time from the roots of Mahonia aquifolium (PURSH) NUTT. in addition to further two bisbenzylisoquinoline alkaloids berbamine and oxyacanthine, which have al ready been found in this species. Seeds of this plant contained the bisbenzyliso quinoline alkaloid isote...
