Halocnemum strobilaceum is a halophyte present in the humid and arid bioclimatic regions of Egypt. The current study aimed at UPLC/PDA/ESI-MSn qualitative chemical profiling of the phytoconstituents underlining both antioxidant and cytotoxic activities of the bio-active fraction in comparison with the other fractions. It resulted in detection of several related compounds to prenylated flavonol ...

A large body of evidence highlights that propolis exerts many biological functions that can be ascribed to its antioxidant and anti-inflammatory components, including different polyphenol classes. Nevertheless, the molecular mechanisms are yet unknown. The aim of this study is to investigate the mechanisms at the basis of propolis anti-inflammatory and antioxidant activities. The effects of two...

An amphoteric (cocamidopropylbetaine, CAPB) and a nonionic (alcohol polyethoxylate, AE) surfactant were characterized by electrospray ionization quadrupole ion trap mass spectrometry (ESI-MS) as to their homologue distribution and ionization/fragmentation chemistry. Quantitative methods involving reversed-phase gradient HPLC and (+)ESI-MSn were developed to directly determine these surfactants ...

Apples (Malus domestica) are one of the most widely grown and consumed fruits in world that contain abundant phenolic compounds possess remarkable antioxidant potential. The current study characterised from five different varieties Australian apples (Royal Gala, Pink Lady, Red Delicious, Fuji Smitten) using LC-ESI-QTOF-MS/MS quantified through HPLC-PDA. content potential were determined various...

Danggui Buxue Tang (DBT) is a Traditional Chinese Medicine (TCM) formula primarily used to treat symptoms associated with menopause in women. Usually, DBT is composed of one portion of Radix Angelicae Sinensis (RAS) and five portions of Radix Astragali (RA). Clinically, Radix Hedysari (RH) is sometimes used by TCM physicians to replace RA in DBT. In order to verity whether the chemical constitu...

BACKGROUND Azorella compacta is traditionally used in the form of tea (infusion), in the Andean region of South America, to treat various chronic diseases. However, the health-promoting properties of this herbal tea have not yet been extensively explored. MATERIALS AND METHODS The free radical scavenging activity of A. compacta infusion (ACI) was evaluated by the 1,1-diphenyl-2-picrylhydrazyl...
