The removal of organic dyes used in many sectors such as textile, paper, leather, and packaging from water sources is very important in terms of preventing the spread of industrial pollutants to the environment. Transition metal complexes supported to an inorganic solid material are frequently used for the degradation/reduction of organic dyes causing this pollution. In this study, new Pd (II) complexes with Schiff base ligands were synthesized and structurally characterized by nuclear magnetic resonance (NMR), Fourier‐transform infrared spectroscopy (FT‐IR), mass spectrometry (MS), and single‐crystal X‐ray diffraction (sc‐XRD) spectroscopic methods. Then, the Al2O3‐impregnated materials of these Pd (II) complexes were prepared and characterized by scanning electron microscopy with energy dispersive X‐ray analysis (SEM‐EDX), FT‐IR, and thermogravimetry (TG) techniques. The catalytic activities of the synthesized Pd (II) complexes and their Al2O3‐impregnated materials were comparatively analyzed to investigate the degradation/reduction of organic dyes (2‐nitroaniline, 4‐nitroaniline, 4‐nitrophenol, eosin yellow, and methylene blue). The catalytic results indicate that Al2O3‐impregnated materials are very active catalysts for the degradation/reduction of organic dyes under those circumstances. Conversions of up to 98% for all substrates were obtained after 5 min at ambient temperature.

Siddha herbo mineral formulation Ayakaandha Abraga Chendhuram indicated as a best choice of drug to treat diabetes. AAC was evaluated for its antidiabetic activity on streptozotocin induced diabetes in rats. At the end of the results, can found that these drug AAC has hypoglycaemic effect. Oral administration of AAC (25mg/kg), significantly reduced the elevated blood glucose levels as the duration of drug administration increases. Further clinical study will be carried out for the benefit of diabetes patients.
