Four new 8,9,30-phragmalin orthoesters (1-4), along with six related known compounds, namely xyloccensins O-S (5-9) and V (10), were isolated and characterized from the twigs and leaves of the Chinese mangrove Xylocarpus granatum. The structures of the new compounds were determined on the basis of extensive spectroscopic analysis and by comparison with those of related known compounds in the literature. The absolute configuration of xyloccensin Q (7) was revised as its enantiomer by X-ray… 
Novel and Neuroprotective Tetranortriterpenoids from Chinese Mangrove Xylocarpus granatum Koenig
TLDR
Eight new tetranortriterpenoids were isolated from the twigs and leaves of the Chinese mangrove plant Xylocarpus granatum, together with four related known ones, and displayed moderate effects against H2O2-induced neurotoxicity in PC12 cells at the concentration of 10 μM.
Ethnomedicinal Use, Phytochemistry, and Pharmacology of Xylocarpus granatum J. Koenig
TLDR
Overall, it can be stated that X. granatum may be one of the hopeful medicinal herbs for the treatment of various diseases in human beings and in-depth studies are required to understand the mechanism of action.
Influence of Pickling Process on Allium cepa and Citrus limon Metabolome as Determined via Mass Spectrometry-Based Metabolomics
TLDR
In general, the pickling process appeared to negatively impact the abundance of secondary metabolites in both onion and lemon, suggesting a decrease in their food health benefits.
