AbstractAn inorganic coordination complex of single crystal containing sodium and aluminum (SA) was grown at room temperature by slow evaporation technique. The crystal was characterized using single crystal X-ray diffraction (XRD), FT-IR, UV-Vis, SHG, SEM, EDX and TG/DTA analyses. The size of the grown crystal was around 17 mm × 15 mm × 5 mm. Both optical and SEM photographs confirmed that the crystal is transparent with smooth surface. The XRD data showed that the crystal belongs to the BCC crystal structure. The crystal shows excellent transparency in the entire region of visible light (cut-off value is 339 cm−1). The dielectric constant as well as dielectric loss of the sample was calculated by varying frequencies at different temperatures and the presence of low dielectric loss proved that this crystal can be used for the NLO application.

The single crystal of cis-2,6-bis(4-chlorophenyl)-3,3-dimethylpiperidin-4-one (4C3DMPO) has been grown using a slow evaporation technique. 4C3DMPO is a non-centrosymmetric crystal which crystallizes in the orthorhombic system with space group Pna21. Benzene is used as a solvent for the crystal growth based on solubility studies. The mechanical studies, using microhardness methods, have also been carried out. The compound is characterised using UV, FT-IR and NMR spectral studies. Furthermore, the thermal stability of the crystal is established by TG/DTA. The nonlinear optical studies (SHG) of the crystal have been determined using the Kurtz and Perry powder technique and the activity observed is 2.5 times greater than that of KDP.

Optically transparent single crystals of potassium acid phthalate (KAP, 0.5 g) 0.05 g and 0.1 g (1 and 2 mol %) trytophan were grown in aqueous solution by slow evaporation technique at room temperature. Single crystal X- ray diffraction analysis confirmed the changes in the lattice parameters of the doped crystals. The presence of functional groups in the crystal lattice has been determined qualitatively by FTIR analysis. Optical absorption studies revealed that the doped crystals possess very low absorption in the entire visible region. The dielectric constant has been studied as a function of frequency for the doped crystals. The thermal stability was evaluated by TG-DSC analysis.

Carthamus tinctorius Linn, also known as safflower, is a plant with the potential of being used in the production of antimalarial drugs. The purpose of this study was to isolate and identify the steroid compounds in the safflower and determine its antimalarial activity in vitro. The isolation process was conducted through extraction and chromatography methods. Then, the characterization of the isolated compounds was conducted through spectroscopic techniques which include Fourier Transform Infrared Spectroscopy (FT-IR), NMR 1-D (1H and 13C-NMR), and NMR 2-D (HMQC, HMBC, and H-H COZY) as well as comparing data with the existing literatures. In addition, the tests conducted were with variations of isolate concentrations (10, 1, 0.1, 0.01, and 0.001 μg/mL) against 3D7 strain of Plasmodium falciparum. Based on the FT-IR spectroscopic data, the steroid compounds isolated from safflowers might be stigmasterols. In addition, the isolates had -OH functional group in the region of 3431 cm-1, C-O in the region of 1053 cm-1, and Csp3-H in regions of 2960, 2934, and 2865 cm-1. The NMR 1-D data showed presence of 29 carbon atoms, while the protons were 48 in number. Furthermore, the IC50 value of the compound was 34.03 μg/mL with a percentage inhibition of 43.92% against the growth of P. falciparum. Therefore, it was classified as inactive agent in inhibiting the growth of malaria parasites, however, it could be used as a marker compound in C. tinctorius Linn extract.
