Phytochemical profiling of spiny coriander (Eryngium foetidum L.) – A potential perennial spicing-culinary herb of eastern India

Abstract

Spiny coriander (Eryngium foetidum L.) is a perennial medicinal herb grown in the tropical regions worldwide. In India, it is used as a potential spice for garnishing and flavoring the dishes and treating several ailments. Eryngium spp. found in coastal Odisha, India has a strong aroma similar to the seasonal Coriandrum. The volatile flavor constituents of the unique plants were analyzed through headspace solid-phase microextraction (HS-SPME) using capillary gas chromatography (GC) and gas chromatography-tandem mass spectrometry (GC–MS/MS). The volatile compounds exhibited high chemodiversity, with 10-undecenal as the major component in leaves (44.98%) and branches (57.43%). Fourier-transform infrared (FTIR) spectroscopy identified eight major peaks grouped into six main regions. Chemo profiles of these two corianders were overlapped and showed similar area differences in the spectral peak. The lesser-known perennial Eryngium with high chemodiversity would be a better alternative to the seasonal coriander for aromatic, pharmaceutical, and industrial uses.

Evaluation of Antifungal Activity of Ag Nanoparticles Synthetized by Green Chemistry against Fusarium solani and Rhizopus stolonifera

“…In the spectrum, the broad band was observed in the wavenumber range from 3700 to 3000 cm −1 and centered around 3300 cm −1 , and it can mainly be attributed to the O-H stretching vibrations of coriander proteins and phenols [ 23 , 25 , 26 ]. A pair of peaks was observed at wave numbers of 2975 cm −1 and 2883 cm −1 , corresponding to the stretching vibrations of the CH 2 group [ 27 , 28 , 29 ]. We also identified a peak at wave number 1654 cm −1 , corresponding to stretching vibrations of the C=C group; we further identified peaks at 1044 cm −1 and 1083 cm −1 associated with the stretching of the C–O–C or C–O groups that, together with C=C groups, are related to phytochemicals such as flavones, alkaloids, phenols and anthracenes that can help generate metallic nanoparticles according to the literature [ 30 ].…”

Molecular Phylogeny, DNA Barcoding, and ITS2 Secondary Structure Predictions in the Medicinally Important Eryngium Genotypes of East Coast Region of India

“…A recent study depicted that the component, 10-undecenal, is the reason for a strong aroma similar to the seasonal coriander in the Eryngium spp. collected from the east coast of India [ 9 ]. This perennial lesser-known herb possesses high chemo diversity importance for the pharmaceutical and aroma industries.…”

“…The correct nomenclature and accurate species identification need the utmost attention for the safe use and commercialization of medicinally important plants. Eryngium is a hemicryptophyte perennial herb with spiny leaf margins, light blue inflorescence, and a tap root system [ 9 ]. Reports on molecular characterization for species discrimination in Eryngium are scanty.…”

“…Reports on molecular characterization for species discrimination in Eryngium are scanty. The subgenera and species of Eryngium have been categorized based on their morphological features, such as leaf margin, color, odor, and chemical constituents [ 9 , 10 ]. A few reports are available on the infrageneric relationship using chloroplast DNA ( trnQ–trnK ) and nuclear internal transcribed spacer ( ITS ) sequencing [ 11 ].…”
