Chemical Fingerprinting of Spiranthes spiralis L. Methanol Seed Extract: Spectroscopic, Chromatographic, and Computational Approaches

open access: yesFood Science &Nutrition, Volume 14, Issue 2, February 2026.
Spiranthes spiralis L. seed methanol extract was morphologically and chemically characterized using microscopy, FT‐IR, GC–MS, and in silico analyses. The extract exhibited high phenolic content and strong DPPH radical scavenging activity, while GC–MS identified 22 bioactive compounds with notable binding affinity toward the GPR52 receptor.
