Abstract

The present work was aimed to carry out pharmacognosical and phytochemical evaluation of individual root, stem, and leaves of orchid “Dendrobium ochreatum.” The plant was sun dried and was grounded to fine powder using mechanical grinder followed by sieving. The fine powder was collected and subjected to different pharmacognostical studies like fluorescence analysis under uv light at different wavelength. Physiochemical parameters were also evaluated of the dried plant parts like ash values, loss on drying. Each part of plant like root, stem and leaves were separated and subjected to extraction using soxhletion using different polarity solvents i,e hexane, chloroform, ethanol in gradient elution technique. All total nine plant extracts were obtained, phytochemical screening revealed the presence of important phytoconstituents like alkaloid, glycoside, saponins etc whereas only chloroform extracts of stem exhibited the presence of steroid/phytosterol.

Abstract

Biomedical waste is defined as the waste generated during the diagnosis, treatment or immunization of human beings or animals or in research activities pertaining thereto or in the production or testing of biological, and including categories mentioned in schedule I of the Biomedical Waste (Management and handling) (second amendment) Rules 2000, by Ministry of Environment and Forests notification. Proper handling, treatment and disposal of biomedical wastes are important elements of healthcare infection control program. There may be increased risk of nosocomial infections in patients due to poor waste management which can lead to change in microbial ecology and spread of antibiotic resistance. It is not only the health of the patient, but also the health of persons in health care industry equally important. This article speaks about how the hospitals present in Guwahati treat their waste material and the effect of the waste in the environment Keywords: Biomedical waste, waste management, effect on environment, risk associate.

Abstract

Polygonum muricatum is widely used by the local people of Meghalaya for anthelmintics. An attempt has been made to evaluate the pharmacognostical, preliminary phytochemical and pharmacological parameters of leaves of Polygonum muricatum. The physicochemical constants like moisture content, ash values such as total ash, acid insoluble ash and water soluble ash, extractive values such as water soluble extractive value and alcohol soluble extractive value were determined. The extract obtained by successive solvent extraction was subjected to preliminary phytochemical analysis to find out the presence of compounds. The plant Polygonum muricatum leaves were extracted with the solvent benzene, acetone, ethanol and water by soxhlet apparatus method. The extract was evaluated for anthelmintic activity with Indian earthworm. Ethanol extract of the plant Polygonum muricatum has shown the significant activity.
