Integrated GC–MS and FT‐NIRS Characterization of Metabolic Differences Between Fresh and Dried Fruits of Five Genus Amomum

open access: yesJournal of Food Biochemistry, Volume 2026, Issue 1, 2026.
Amomum is a diverse genus whose metabolites are dominated by volatile compounds; however, differences in metabolism levels between fresh and dried fruits remain unclear. Our results indicated that metabolite differences between fresh and dried fruits were expressed in relative content rather than in species.

Sesquiterpene Lactones from Staehelina fruticosa

open access: yesJournal of Natural Products, 2008
The phytochemical analysis of Staehelina fruticosa led to the isolation of four germacranolide-type sesquiterpene lactones (1- 4), including two new glycosides. The structures of these sesquiterpene lactones were elucidated using spectroscopic techniques, and enzymatic hydrolysis was carried out to confirm the nature of the two glycoside derivatives ...
