Metabolic exploration of the developmental abnormalities and neurotoxicity of Esculentoside B, the main toxic factor in Phytolaccae radix.

P: radix is a perennial herb, and its extracts have various biological properties that make it a potential candidate for the treatment of tumors, edema, and lymphatic stasis. However, the main factor contributing to its toxicity are not clear. Here, we used a zebrafish toxicological model to study the main toxicity factor of P.

Metabolomic navigated Citrus waste repurposing to restore amino acids disorder in neural lesion.

The fruit juice food industry produces huge waste annually, mainly Citrus peel and seeds. We investigated their chemical composition using hydrophilic interaction chromatography (HILIC-) and reverse phase liquid chromatography tandem mass spectrometry (RPLC-MS/MS), revealing 277 compounds, mainly containing flavonoids and limonoids. As the primary representative component in Citrus waste, limonin was selected to be explored new bio-functions.

Metabolomics Mechanism and Lignin Response to Laxogenin C, a Natural Regulator of Plants Growth.

Laxogenin C (LGC) is a natural spirostanol deriving from plant hormone which has shown growing regulation similar to those of brassinosteroids. In the present study, LGC showed a promoting effect on tomato seed germination and seedling growth in a dose-dependent manner. We applied LC-MS/MS to investigate metabolome variations in the tomato treated with LGC, which revealed 10 differential metabolites (DMs) related to KEGG metabolites, associated with low and high doses of LGC.
