Chemical profiling and biological activities of the roots of Allochrusa gypsophiloides.

ABSTRACT

Allochrusa gypsophiloides is one of the best-known endemic saponin bearing food plants of Central Asia. However, the plant's secondary metabolites remain unmapped. The current study aimed to chemical profile of the metabolite in the plant roots by an untargeted UHPLC-ESI-MS, together with the isolation of the major compounds followed by a 2D NMR and HR-MS for identification and evaluation of the antioxidant and enzyme inhibitory activity of the extracts. The results revealed the presence of 48 putatively annotated metabolites comprising triterpene glycosides, phenolic compounds and their derivatives, organic acid glycosides, and lignan glycosides. The chromatographic separation and purification of the extract resulted in the isolation of four compounds where two new compounds and along with two known triterpenes were reported. The ethanol/water extracts showed a maximum effect in antioxidant assays, while the ethyl acetate extract achieved the best effect in the enzyme inhibitory assays.
