“…In the region of 600 and 660 cm -1 wavenumber two peaks were noticed due to the bending vibration of SO 4 2group. Similar types of bending vibrations were reported in the literatures [31,32]. On the other hand, asymmetric stretching vibration was resulted in the region of 1118 cm -1 wavenumber for the presence of SO Please do not adjust margins and 3541 cm -1 .…”

Gypsum products (calcium sulfate dihydrate, CaSO4·2H2O) were synthesized through an eco-friendly and low-cost process by two different renewable calcium carbonate sources (CaCO3), hen and duck eggshell wastes, with product yields obtained of 84.73 and 87.74%, respectively. The X-ray fluorescence results indicated that calcium oxide (CaO) and sulfur trioxide (SO3) are the major elemental components of CaSO4·2H2O prepared from both calcium sources. The Fourier transform infrared results confirmed the vibrational characteristics of SO42− and H2O functional groups in the chemical structure of the prepared samples. The X-ray diffraction patterns of CaSO4·2H2O prepared from both calcium sources confirmed the sample’s crystal structure as well as the chemical formula, after comparing them to the standard powder diffraction file. The crystallite sizes of CaSO4·2H2O products were calculated from the experimental diffraction peak through the Scherrer equation and found to be 19–20 nm. The positive preferential growth (Pg) value highlighted the excellent stability of the synthesized CaSO4·2H2O. The scanning electron microscopic results showed the agglomeration particles of hen- and duck-CaCO3 raw agents, whereas plate-like particles were observed for hen- and duck-CaSO4·2H2O products but the particle sizes were different.

“…The lower concentration of lipid molecules with a long carbon chain in tubers made these peaks more uncertain. Unlike tuber parts, carbonyl peaks in the 1734 cm À 1 C=O ester bond, which are seen only in flower parts, [33] aromatic structures of 1506 cm À 1 C=C, [35] 1231 cm À 1 shows the CÀ O peaks of phenolic structures [36] and 827 cm À 1 shows the out-of-plane CÀ H peaks observed in alkenes and aromatic compounds [38] .Spectral analysis revealed that the first and second tubers are identical, but there are differences in the flowers. According to these data, the functional groups in the studied organs of A. coriophora are polysaccharides, lignin, and proteins.…”

This study aims to investigate the functional groups and phytochemical profile of Anacamptis coriophora seeds, tubers, and flowers. Symbiotic seedlings produced using the ex vitro method were transferred to their natural habitat and grown to analyze the functional groups and phytochemical profiles of tubers and flowers. The life cycles of the transferred seedlings were monitored, and tubers and flowers were harvested for analysis. ATR‐FTIR spectroscopy revealed the presence of functional groups such as polysaccharides, lignin, and proteins in both tubers and flowers. Differences in spectral frequencies between first‐year and second‐year tubers were observed. Fatty acid analysis identified 30 different compounds in seeds, flowers, and tubers, with linoleic acid being the most abundant (27% in seeds, 33% in tubers), and palmitic acid present in flowers (24%). GC‐MS analysis of ethanol extracts from these components highlighted the presence of 32 compounds, including hydroxyacetic acid, hydrazide, cytidine (Z)‐7‐hexadecenal, 2,2‐dimethoxyethane, 2,5,6‐trimethyldecane, and butanamide, 4‐amino‐N‐hydroxy. A. coriophora's tubers, flowers, and seeds may contain active metabolites with therapeutic potential. These results are valuable for the commercial cultivation of the plant.
