Study on the Screening of Anti‐Osteoporosis Components in Processed Epimedium‐Based on Spectrum‐Effect Analysis

Chemistry &Biodiversity, EarlyView.
ABSTRACT Epimedium (EP) is a traditional Chinese medicine that has been used to treat osteoporosis for several years, but its mechanism of action is unclear. We used ultrahigh‐performance liquid chromatography coupled with triple–quadrupole mass spectrometry (UPLC–QQQ–MS/MS) to detect the components of raw and processed EP samples.

Piper auritum (Kunth) Fungal Endophytes: A Source of Metabolites to Inhibit the Formation of Advanced Glycation End Products

Chemistry &Biodiversity, EarlyView.
Endophytic fungi of P. auritum were evaluated for their ability to produce inhibitors of formation of advanced glycation end products (AGEs). Neopestalotiopsis sp. H2 and Diaporthe sp. H5 extracts were the most active. So, we performed their chemical profiling by untargeted and phenolics‐targeted metabolomic approaches to identify the potential ...
