“…Our previous study showed the similar antioxidant abilities of free phenolic extracts from rambutan peel compared with Vc and BHT (Sun et al, 2012). Zhao et al (2015) reported the similar or higher antioxidant capacities of isolated compounds from the roots and stems of Stauntonia brachyanthera compared with Vc and quercein.…”

Summary The crude rambutan peel phenolic (RPP) extracts were purified by resin adsorption technology. NKA‐9 resin with the best adsorption capacity and desorption ratio was chosen to dynamically purify crude RPP. Adsorption capacity and desorption ratio of NKA‐9 resin were 91.85 mg gallic acid equivalent (GAE) g−1 and 90.45%, respectively. Purification processes enriched total phenolic content, and the contents in crude and purified RPP were 579.72 and 877.11 mg GAE g−1 extract powder, respectively. Phytochemical compounds of RPP were qualitatively and quantitatively indentified by mass spectrometry. Purification of the resin as expected elevated the concentrations of major phenolic compounds, especially geraniin and ellagic acid. Antioxidant and antiglycation activities of crude and purified fractions were evaluated in vitro. Crude and purified RPP had high inhibitory effects on oxidation and glycation, and purified RPP showed stronger bioactivity than crude RPP (P < 0.05), which might be due to their differences in phenolic profiles.

“…The radical scavenging activities of the isolated compounds were carried out using an improved ABTS decolourisation assay with some modifications (Zhao, Guo, Zhang, Meng, & Sha, 2015). ABTS radical cation (ABTS• + ) was produced by reaction of 7 mM stock solution of ABTS with 2.45 mM potassium persulphate (final concentration) and allowing the mixture to stand in the dark at room temperature for 12-16 h before use.…”

Available online A B S T R A C TFour new phenolic compounds, vitexnegheteroins A-D (1-4), were isolated from the seeds of Vitex negundo var. heterophylla, together with eight known compounds. Their structures were established on the basis of extensive 1D and 2D NMR experiments, as well as their mass spectroscopic data. The absolute configuration of compound 4 was determined by comparing its experimental CD spectrum with that calculated by the time-dependent density functional theory (TDDFT) method. The antioxidant and anti-inflammatory activities of these phenolics were also evaluated. Most of the compounds showed strong ABTS radical scavenging activities and all the tested isolates exhibited inhibitory effects on lipopolysaccharideinduced NO production in murine microglial BV-2 cells. The bioactive studies supported the traditional use of this edible aromatic plant and disclosed the potency of it to be developed as new antioxidant and anti-inflammatory functional food.

“…Furthermore, S. brachyanthera is traditionally accepted by local people for the treatment of various diseases and symptoms such as pain, inflammation and also used as diuretics for a long time (Chen & Meng, 2013). Our previous studies on this plant resulted in the isolation of more than 30 known compounds (Chen, Li, Meng, Li, & Li, 2011;Wang, Zhu, Meng, Li, & Li, 2012;Zhang, Zhu, Meng, Li, & Li, 2012) and some of them have proven to have potential antioxidant activities (Zhao, Guo, Zhang, Meng, & Sha, 2015). Nor-oleanane triterpenoid saponins, the main constituents of the plant, have been confirmed to possess diverse biological activities like hepatoprotective effects and gastrointestinal tract protection (Xu, Zheng, & Meng, 2013), which indicate its potential possibility to be a hepatoprotective agent in the health industry, and the additional values of the plant as economic crop in agriculture.…”
