Abstract: Medicinal plants play an essential role in the development of human life. Medicinal plants are used by local people to cure various diseases. All the plants in this study were biologically active and were used for different ailments. Phytochemicals are bioactive compounds obtained from the plant and are widely applied in the traditional herbal medicine. Preliminary screening of phytochemicals is a valuable step in the detection of bioactive principles present in medicinal plants and may lead to novel environmentally friendly drug discovery. The objective of the study was to screen such phytochemicals in selected Nigerian medicinal plants. Fresh plant material (leaves) were collected and processed prior to phytochemical screening. Alkaloids, glycosides, flavonoids, saponin, tannin, steroids, phenols and protein distribution in six medicinal plants belonging to different families were assessed and compared using aqueous and ethanolic leave extract. The medicinal plants investigated were Parkia biglobosa, Boswellia dalzielli, Carica papaya, Bridelia feruginea, Acalypha wilkesinia and Anogeissus leiocarpus. It was observed that almost all the plant leave extract (aqueous and ethanolic) contains the important phytochemicals like alkaloids, saponin, tannin and phenol. It was concluded that the plants studied were rich in phytochemicals with significant pharmacological and medicinal applications. Hence, the use of the medicinal plant should be encouraged.

Abstract: The present research trail was carried out after harvest of maize crop on calcareous soil (19% lime on w/w basis) of Pakistan, District Nowshera soil series [Piedmont alluvium, silty clay loam, Ustochrept] to study its chemical properties as affected by application of organic manures of different sources integrated with urea. The treatments of the present study were divided into 3 groups based on the combination ratios such as 1:1, 3:1 and 1:0. Total 13 treatments such as: T1=alone Urea (control), T2 [Urea+SSB (1:1)], T3 [Urea+SCB (1:1)], T4 [Urea+PL (1:1)], T5 [Urea+FYM (1:1)], T6 [Urea+SSB (3:1)], T7 [Urea+SCB (3:1)], T8 [Urea+PL (3:1)], T9 [Urea+FYM (3:1)], T10=alone SSB, T11=alone SCB, T12=alone PL, T13=alone FYM were used and each treatment was replicated thrice. The combination ratios of the treatments were based on %N (required amount of N is 120 kg/ha) received from Urea and organic manures. Results of the experiment revealed that all the treatments have significantly affected (P>0.05) the soil chemical properties such as pH, E. C, total nitrogen content and organic matter content while bulk density was non-significant. By comparing various treatments groups, treatments having 1:1 combination ratio (T2, T3, T4 and T5) have shown best results in case of pH, E. C and nitrogen content of post-harvest soil. They have mediated the pH and E. C to levels favorable for plant growth and N uptake. While in case of organic matter content maximum results were obtained for treatments having combination ratio of 1:0 i-e (T10, T11, T12 and T13). From the present study it was concluded that all the treatments except control have altered the chemical status of soil to a favorable soil enviro responsive microbial activity and plant growth. Such studies on different soil series under different climatic conditions is advised for wide spread application and authorization of results.

Abstract: Peroxidases, widespread in the biological world, are a kind of oxidoreductases important in biological antioxidant defense systems. For great potential value of them in physiology, biochemistry and treatment of industrial pollutants, etc., they receive extraordinary attention, and also a large number of peroxidases have been found and studied on the nature and catalytic properties of them to date. Especially, horseradish peroxidase is first found and given more researches on the protein structure, catalytic mechanism and practical applications, and even modified by gene engineering and protein engineering to improve its catalytic performance. In addition, also there are numerous peroxidases that are derived from various sources or used for catalytic oxidation of different substrates, which have many differences from horseradish peroxidase in amino acid composition, active site structure, catalytic characteristics and corresponding applications. To better study and selectively employ peroxidases as biocatalysts, it is critical to comprehensively recognize various peroxidases, so as to present a reference for the in-depth and accurate studies on them in the future. In this paper, various peroxidases usually focused by enzymologists are reviewed for better mastering the completed research work on them, understanding the main interests in them, and knowing the advantages and disadvantages of them. Moreover, the research aspects that hereafter may be focused on are prospected.
