Desta, Kebede Taye published the artcileAntioxidant activities and liquid chromatography with electrospray ionization tandem mass spectrometry characterization and quantification of the polyphenolic contents of Rumex nervosus Vahl leaves and stems, HPLC of Formula: 69097-99-0, the publication is Journal of Separation Science (2016), 39(8), 1433-1441, database is CAplus and MEDLINE.

In the present study, four compounds, viz., hlorogenic acid, catechin, orientin, and apigenin-O-acetylglycoside, among 18 polyphenol compounds (17 flavonoids and one hydroxycinnamic acid derivative) were characterized for the first time in Rumex nervosus leaves and stems by using liquid chromatog. with electrospray ionization tandem mass spectrometry. The method validation in terms of determination coefficient, limits of detection, and quantification were ≥ 0.9979, 0.68-1.61, and 2.27-5.38 mg/L, resp. Accuracy, expressed as percent recovery for two spiking levels (10 and 50 mg/L), were in the range 78.9-110.6% with the exception of caffeic acid. The relative standard deviations were 1-17%. The total polyphenol content was higher by approx. two times in the leaf (1073 mg/kg fresh sample) than in the stem (519.86 mg/kg fresh sample). The antioxidant effects increased in a dose-dependent manner, and the scavenging activities, investigated by measuring 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) scavenging activity, ferrous ions chelating activity, superoxide anion radical scavenging activity, and ferric reducing antioxidant power activity, were significant (p < 0.05) using low concentrations of the leaf extract Overall, the present study suggests that different parts of R. nervosus have great potential for producing a range of extracts with potential applications in medicine.
