Characterisation of flavonoids in Orostachys japonicus A. Berger using HPLC–MS/MS: Contribution to the overall antioxidant effect

Chemical composition and antioxidant activity of a Lebanese plant Euphorbia macroclada schyzoceras

“…The sticky residue was loaded onto a silica gel column and eluted with methanol/dichloromethane (1:1, 300 mL). The solvent was removed to give a mixture of flavonoids, which is analyzed in LC-MS and NMR instrument to determine their structure [12] . …”

Orostachys japonicus induce p53‐dependent cell cycle arrest through the MAPK signaling pathway in OVCAR‐3 human ovarian cancer cells

“…Orostachys japonicus is reported to contain 16 types of flavonoid contents. They have been confirmed to have antioxidant activity using DPPH assay (Lee et al., 2011). However, the exact activity of its physiological effects and the cell signaling pathways involved remain unknown.…”

Phenolic Characterisation and Antioxidant Activity of Primula vulgaris and Its Antigenotoxic Effect on Fibroblast Cells

“…Determining the antioxidant activity of the tested natural product is therefore accepted as a starting point for more comprehensive studies (21). Many in vitro assay are used to determine the antioxidant capacity of herbal extracts, and at least two different methods are recommended (22,23). Total phenolics content is often used to examine the antioxidant properties of plant extracts since it is useful, rapid, and costeffective (24).…”
