The water quality of six drinking surface water sources of Pithoragarh district of hilly state Uttarakhand has been accessed. The spatial and temporal variations of water quality parameters have been explained with the help of Box and Whisker plots. The selected surface water sources of Pithoragarh district were evaluated on pre-monsoon and post mo...

The seasonal variation in surface water quality of district Bageshwar, Uttarakhand (India) has been evaluated for 3 years from 2010 to 2012 for determining the suitability of water for drinking and irrigation needs. Water samples collected from different drinking water sources during pre-monsoon and post-monsoon seasons in each year were analysed f...

This review highlights the pharmacology, biological properties and traditional uses of a very important folklore medicine, known as ‘Keeda jadi’. In nature, it is found at high altitudes of 3500-5000 m on the high Himalayan mountains in India, Nepal and Tibet. It is an entomo-fungal combination of a larva of small moth, Hepialus armoricanus and a p...

In the present study, groundwater quality of district Udham Singh Nagar was evaluated using chemometric techniques, such as cluster, principal component and factor analysis to investigate the spatial variation of the most significant water quality parameters and to determine origin of pollution sources. Water samples collected from 6 sampling sites...

Water quality of Himalayan Rivers has been steadily deteriorating over several decades due to anthropogenic activities, dumping of treated or untreated effluents, poor structured sewerage and drainage system etc. In the present study, the water quality of five important rivers namely Gola, Kosi, Ramganga, Saryu and Lohawati Rivers were investigated...

In the present study, seasonal variation in hydrochemical characters of Kosi River water has been evaluated and assessed the suitability of water for human consumption and irrigation purposes. Water samples were collected during pre-monsoon (PRM) and post-monsoon (POM) seasons of the years 2010 and 2011 and analysed for various physico-chemical, me...

The Ganga Canal emerging out from Ganga river has great ritual importance among pilgrims and tourists at Haridwar, Uttarakhand, India. The Canal is being polluted due to mass bathing, washing, disposal of sewage, industrial waste and these human activities are deteriorating its water quality. To determine the impact of these activities, Ganga Canal...

The purpose of the study was to examine the variation in the essential oils composition of Juniperus wallichiana collected from four different locations of North-Western Himalaya of Uttarakhand (India) as well as antimicrobial activity against six clinical isolate microbial strains. The essential oils were obtained through hydro-distillation of the...

Objective The purpose of this study was to evaluate the essential oil composition as well as antibacterial activities of essential oil and leaves extracts of Lantana camara against five bacterial strains.Methods Essential oil was obtained by hydro-distillation from the leaves and analyzed by GC and GC-MS. The antibacterial activities of essential o...

The essential oils obtained by hydro-distillation of shade dried leaves, seeded leaves and pericarp of Zanthoxylum armatum were analyzed by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS) led to the identification of 23, 21 and 24 different constituents, representing 99.5%, 99.3% and 99.2% of the total oils. The volatil...

The volatiles constituents obtained by hydro-distillation of all the aerial parts of two Lamiaceae plants were analyzed by GC and GC/MS. The Hyssopus officinalis (L.) was collected from Malari (Chamoli) while the Thymus serpyllum (L.) collected from three places Malari; Indradhara near Badrinath (Chamoli) and Chakrata (Dehradun) of the Garhwal regi...

The freshwater resources are under siege in Uttarakhand. More than 2 million people do not have consistent access to clean water and more than twice that number lack access to sanitation in hills as well as plan areas of the state. Surface drinking water sources are disappearing and level of ground sources is falling abruptly. Moreover, water quali...

ABSTRACT Objective: The purpose of this study was to evaluate the essential oil composition as well as antibacterial activities of essential oil and leaves extracts of Lantana camara against five bacterial strains. Methods: Essential oil was obtained by hydro-distillation from the leaves and analyzed by GC and GC-MS. The antibacterial activities of...

Objective: To examine the composition of Cinnamomum tamala and Murraya koenigii essential oils and their antimicrobial activities against nine microbial strains. Methods: Essential oils were obtained by hydrodistillation from the leaves of two spice trees and were analyzed by GC and GC/MS. The oils were also tested for their antimicrobial activity...

A new isocratic reversed-phase high performance liquid chromatographic (HPLC) method with diode-array UV detection was developed and validated for the determination of lisinopril in pharmaceutical formulation. The method validation of lisinopril was performed by using Nucleosil (125 x 4.0mm, 5mm) as stationary phase with mobile phase consisting of...
