Abstract
Cestrum nocturnum Linn. belongs to solanaceae. It is commonly known as Raat rani, lady of night or night Jessamine have great medicinal value. The plant was extracted using conventional extraction as well as microwave assisted extraction. The phytochemicals such as carbohydrate, proteins, amino acid, glycoside, phenolic compounds and tannins has been qualitatively determined. The physicochemical properties such as relative density, viscosity, surface tension and refractive index were determined. All properties of microwave assisted extract were found to be more than aqueous extract. UV-Vis and IR data was compared. The extract was screened for biological activity and aqueous extract is found to be active against E. Coli, B. Subtillis, S. Typhi, S. Aureus, Tuberculosis, Malaria
Highlights
Plants are the vital source to combat the severe diseases in the world.[1]
World health organization (WHO) reported that the more than 80 % of the world population used the remedies based on plants for their primary health care need.[2,3]
Antibacterial activity is investigated by cup plate method in which 70 μL of standard test solution was added in each cups or wels and these cups were prepared by using sterile metal borer
Summary
Plants are the vital source to combat the severe diseases in the world.[1]. World health organization (WHO) reported that the more than 80 % of the world population used the remedies based on plants for their primary health care need.[2,3] The plants are the source for the new drugs, in which the majority are still unexplored. Among the 25 000 000 to 50 000 000 plant species - several percentages of the plants are investigated for their phytochemical and biological screening.[4] India is known for the thousands of species for its medicinal value and the use of the different parts of the plant to cure specific alignment.[5]. The extraction and analytical methods of phytochemical and physico-chemical parameters like relative density, viscosity, surface tension and refractive index along with phytochemical qualitative tests were carried out as described in our earlier reports.[13,14,15,16] The UV-visible spectra were recorded in the range from 190 to 800 nm by using double beam spectrophotometer of Model Elico-159 and λmax values were determined. Antibacterial activity is investigated by cup plate method in which 70 μL of standard test solution was added in each cups or wels and these cups were prepared by using sterile metal borer. For the present study Streptomycine is used as a standard against bacterial culture
