Extraction optimization, purification and antioxidant activity of procyanidins from hawthorn (C. pinnatifida Bge. var. major) fruits

Recovery, concentration and purification of phenolic compounds by adsorption: A review

“…At acidic pH, the uptake of phenolics by different adsorbents is enhanced because the phenols are undissociated and the dispersion interactions predominate (Grant and King, 1990;Dargaville et al, 1996;Dabrowski et al, 2005;Mohanty et al, 2005;Mohan and Karthikeyan, 1997;García-Araya et al, 2003;Ugurlu et al, 2005;Caqueret et al, 2008). Hydrogen may plays an important role (Chanda et al, 1983;Grohmann et al, 1999;Ku and Lee, 2000;Ku et al, 2004;Kammerer et al, 2010a;Navarro et al, 2008a;Saleh et al, 2008;Bretag et al, 2009a;Bretag et al, 2009b;Zhang et al, 2009b;Liu et al, 2010a;Liu et al, 2010b;Pompeu et al, 2010). At alkaline pH adsorption decreases since dissociation of hydroxyl groups and carboxyl groups occur (Yoon et al, 1997;Fu et al, 2005).…”

Simultaneous determination of vitexin-4″-O-glucoside, vitexin-2″-O-rhamnoside, rutin and vitexin from hawthorn leaves flavonoids in rat plasma by UPLC–ESI-MS/MS

“…[2,3]. Today, HLF are known to exhibit a wide variety of pharmacological functions like cardiovascular regulation [4], hypolipidemic [5], antioxidative [5][6][7], anti-inflammatory and ␣-glucosidase inhibitor effects [8].…”

Identification of bioactive ingredients with immuno-enhancement and anti-oxidative effects from Fufang-Ejiao-Syrup by LC–MS n combined with bioassays

“…A number of studies have validated the blood enriching effect and anti-fatigue activity of Radix Rehmanniae Preparata polysaccharides [10]. It is also reported that Crataegus pinnatifida Bge extract had antioxidant activity [11] and neuroprotective effect [12]. These previous works have provided valuable information about bioactivities of FES, which would facilitate further systematic investigations on this TCM preparation.…”
