Characterization of alkaloid profile of L. and subsp. (Kreyer) Avet by LC-MS and NMR.

The alkaloid profile of L. and subsp. (Kreyer) Avet have not been characterized yet.

Qualitative and Quantitative Phytochemical Analysis of Hairy Root Cultures.

Hairy root cultures are genetically and biochemically stable, and they regularly possess the same or better biosynthetic capabilities for specialized (secondary) metabolite production compared to the intact plant. species are well-known herbal remedies in ethnopharmacology and rich sources of isoflavonoids. Besides isoflavones, less prevalent isoflavones and pterocarpans with valuable biological effects can be found in species as well.

Quantitative determination of isoflavonoids in Ononis species by UPLC-UV-DAD.

Introduction: The root of the Ononis species has been used internally and externally in ethnomedicine for centuries and contains biologically valuable isoflavonoid compounds. Therefore, it is important to obtain quantitative information about the isoflavonoid profile of these plants.

Objectives: In this article we aimed to develop an optimised sample preparation protocol alongside a validated method for the quantitative measurement of isoflavones, isoflavanones and pterocarpans in the form of glucosides and aglycones, in order to compare the specialised metabolites of Ononis spinosa L.

Separation and characterization of homopipecolic acid isoflavonoid ester derivatives isolated from Ononis spinosa L. root.

Spiny restharrow root (Ononis spinosa L.) and its preparations are mainly used for the treatment of urinary infections or bladder stones in numerous countries. Spiny restharrow root is rich in isoflavonoids (formononetin, calycosin and pseudobaptigenin), pterocarpans (medicarpin and maackiain) and dihydroisoflavonoids (onogenin and sativanone), which metabolites are present as glucosides, glucoside malonates, glucoside acetates and free aglycones in the root.

[Phytopharmacological review of bathurst burr (Xanthium spinosum L.)].

Bathurst burr (Xanthium spinosum L.) is an invasive species that is also known as a medicinal plant. Our goal is to make known the plant and its therapeutic effects in larger scale.

Characterization and identification of isoflavonoid glycosides in the root of Spiny restharrow (Ononis spinosa L.) by HPLC-QTOF-MS, HPLC-MS/MS and NMR.

Restharrow root has been used in traditional medicine for thousands of years; however, the active ingredients responsible for the diuretic effect are still unknown. Previous studies have proved that the root extract contains isoflavonoids, however only few derivatives were identified, mostly relying on retention times or UV data. The aim of our work was to perform a detailed structural characterization of the complete isoflavonoid profile in the aqueous-methanolic extract of Ononis spinosa root by high-performance liquid chromatography coupled with electrospray ionization accurate-mass quadrupole time-of-flight and tandem mass spectrometry in positive ionization mode (HPLC-ESI-QTOF-MS, HPLC-ESI-MS/MS) and nuclear magnetic resonance spectroscopy (NMR).

Targeted tumor therapy by Rubia tinctorum L.: analytical characterization of hydroxyanthraquinones and investigation of their selective cytotoxic, adhesion and migration modulator effects on melanoma cell lines (A2058 and HT168-M1).

Background: Alizarin and purpurin are di- and trihydroxyanthraquinones derived from Rubia tinctorum L. Previous pharmacological studies have demonstrated that they exhibit certain degree of selective inhibitory effects towards cancer cells suggesting their application as a targeted drug for cancer. Our present work was aimed to investigate the suitability of hydroxyanthraquinones of Rubia tinctorum L.

HPLC-ESI-MS/MS of brain neurotransmitter modulator lobeline and related piperidine alkaloids in Lobelia inflata L.

There is a renewed interest in lobelia alkaloids because of their activity on the central nervous system. Lobeline, the most active of them, a nicotinic receptor ligand and neurotransmitter transporter inhibitor, is a candidate pharmacotherapy for metamphetamine abuse. In the present work, high-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometry in positive ion mode was used for investigating the alkaloid profile in Lobelia inflata L.

Simultaneous analysis of hyoscyamine, scopolamine, 6beta-hydroxyhyoscyamine and apoatropine in Solanaceous hairy roots by reversed-phase high-performance liquid chromatography.

A new high-performance liquid chromatographic method is described for tropane alkaloid analysis in genetically transformed root cultures of Datura innoxia Mill. and Atropa belladonna L. Sample preparation, tropane alkaloid extraction with chloroform-methanol-concentrated ammonia 15:5:1 (v/v/v), was followed by solid-phase extraction on Supelclean LC-18 cartridges.
