Tribal people in India traditionally practiced to use available spice materials in cooking, medicine, food preservations and as well as in perfumes. Zanthoxylum rhetsa DC is thorny tree growing in different region of India. Its extract has multiple effect like antioxidant, anti-inflammatory, antimicrobial, antibacterial etc. The present work designed to study the antioxidant effect of zanthoxylum rhetsa DC dry fruit in controlling rancidity of groundnut oil. Peroxide value and para anisidine value of dried coarse powder and methanol extract in groundnut oil were found to be controlled in compare to the blank oil at incubated temperature 60oC. Duration of 20 days’ incubation at 60oC, the 1 gm dry fruit powder and methanol extract of 1 gm powder in groundnut oil shown peroxide and para anisidine values 16.8meqO2/kg, 16.5 meq O2/kg and 17.4, 17.9 respectively to that of blank oil 19.4 meqO2/kg as peroxide value and 20.3 para anisidine value. The control butylated hydroxyl toluene (BHT) and -tocopherol recorded a peroxide and para anisidine value11.6 meq O2/kg, 16.3 meq O2/kg and 9.3, 10.4 resspectively. The ethanol, ethyl acetate and water extract have maximum peroxide and para anisidine values (19.7, 20.1, 20.9 meqO2/kg and 21.1, 22.2, 22.3) with the control and blank oil. Dry fruit coarse powder as whole and 1gm methanol extract stabilize the groundnut oil by controlling primary and secondary oxidation. This study suggested that the dry fruits of Zanthoxylum rhetsa DC is natural antioxidant to control rancidity of groundnut oil
The synthesis of some copper (II), cobalt (II), nickel (II) and iron (II).Complexes of norfloxacin (Nor) are studied & reported. Their structures were elucidated by elemental analysis, UV and IR Spectroscopy. It was observed from the study that norfloxacin molecule coordinated to metals through the two oxygen of the 3- carboxylate and 4-keto groups. Antimicrobial and toxicological studies carried out on some of the products showed a level of antimicrobial activity and toxicity comparable with their respective parent drug.
