Anti-viral and in-vitro free radical scavenging activity of leaves of rubia cordifolia

The aim of this research was to develop the pharmacognostical parameters and phytochemical screening along with histological studies and the leaf powder of Rubia cordifolia. The dried leaves of Rubia cordifolia. (Family: Rubiaceae) were subjected to standardization by following pharmacognostical and phytochemical screening methods. Rubia cordifolia was investigated for preliminary phytochemical analysis and characterization by various instrumental techniques. Methanolic extracts of Rubia cordifolia leaves was very good antibacterial activity and also minimum inhibitory concentrating of different virus using HEL cell cultures, HeLa cell cultures and Vero cell cultures but MIC of Herpes simplex - 1 and 2, vaccinia virus, vesicular stomatitis and Herpes simplex-1 (TK ACVI) were observed very good antiviral activity of Rubia cordifolia leaves DMSO extracts has good minimum cytotoxic concentration activity and also screening for various pharmaceuticals activities. Such as anti oxidant and microbial activities. Keywords: Antiviral and Microbial activity, Phytochemical and Pharmacognostical screening, DPPH, free radical scavenging activity, Rubia cordifolia

Effective Use of Ferrous Sulfate and Alum as a Coagulant in Treatment of Dairy Industry Wastewater

ABSTRACT Dairy plants need usually large quantities of clean water. More than 90% of clean water is converted into wastewater demonstrating very high potential risk of environmental pollution. The present study was undertaken to compare, under the same analytical conditions, the efficiency of ferrous sulfate and alum used as coagulant in chemical treatment of raw wastewater collected from dairy plant. Results of visual and physicochemical evaluation of chemically treated wastewater indicated significant improvement of their selected characteristics, however different response to the coagulant treatment was observed within the tested samples. Removal efficiencies for individual parameters varied in the wide range between 20.9 and 97.2%

The novel compound structures have been established on the basis of their substituted N-chloro aryl acetamide derivatives. All the compounds have been characterized by FT-IR, mass spectra, 1H and 13C NMR spectroscopy. These new compounds have been evaluated for their in vitro antibacterial and anti-fungal activities.</span
