The present study elucidates the secondary metabolite profile of leaves of Pseudarthria viscida, one of the main ingredient of dasamula in Ayurveda. Alkaloids, phenolic compounds and flavonoids were estimated in different solvent-extracts. Acetone extract of leaves showed highest content of phenols and flavonoids. The leaves are quite rich in alkaloids and is found to be 1.9 mg g-1. GC-MS analyses revealed the presence of 20 major volatile organic compounds and were identified by their mass fragmentation pattern in comparison with NIST library. Most of the compounds have antioxidant, anti-inflammatory, antimicrobial and anticancer properties. The present study has identified a major compound Neophytadiene which is a well-known enzyme...

Bacterial pathogens are known to pester Mankind from times immemorial; even though significant efforts in getting rid of these harmful microbes have been made the results are very faint with only few organisms that have been eradicated, such as Small pox virus. But the efforts to eradicate bacterial diseases have shown no passable results as in case of viruses. This is due to the exceptional adaptation and transformation abilities of bacteria to varying environmental Conditions. Though a large number of antibiotics are being used from decades now, there are no affirmative solutions available due to resistance developed towards antibiotics by these bacteria. This resistance developed by the bacteria calls for dire necessity to discover new drugs which can at least reduce the hazards posed by these microbes if not eradication. Hence in this study we have focused on bio prospecting of Clerodendrum paniculatum and Saraca asoka against the highly virulent and extremely adaptable organisms E. coli and K. pneumoniae which currently pose a severe threat to humans due to...

A series of novel 2-Benzamido-3-(4-nitrophenyl)-N’-(substituted) benzylidene-acrylohydrazide (4a-l) analogues were designed by incorporating the few pharmacophoric fragments to enhance the activity profile of molecules. Title compounds were synthesized by the microwave irradiation of α-Benzamido-(4-nitro)-cinnamahydrazide (3) reveals with aromatic/ heteroaromatic aldehydes under acidic conditions, characterized by IR, 1H & 13C NMR, Mass and evaluated for antimicrobial activity by using Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis and Candida albicans strains. Compounds 4e and 4k exhibited significant protection against bacterial strains (MIC: 3.12-50µg/ml; 3.12-100µg/ml respectively) and compound 4h showed better activity (MIC: 12.5 µg/ml) against fungal strain. And also molecular docking interactions with FAB protein for evaluating the antimicrobial activity was done by using XP GLIDE module of Schrodinger suite and this study highlights, all the analogues exhibited significant affinity towards the 5BNM (FAB Protein) have good docking scores (-4.51 to -8.78) than standard drug ciprofloxacin (-4.74). Of the 12 new analogues, compound 4e was identified as most active ligand with good activity profile against bacterial strains and also have higher...

Aim and Objective: To evaluate the antioxidant property of fish oil by its free radical scavenging activity using three different antioxidant models. Materials and Methods: In vitro antioxidant activity of fish oil was evaluated by DPPH radical scavenging activity, lipid peroxidation, ABTS radical scavenging activity using olive oil as positive control. Different concentrations of the fish oil, 0.02 – 4 mg/ml were used for the free radical scavenging activity by different method and the IC50 value was calculated. Results: Different concentrations of the fish liver oil exerted a dose dependant free radical scavenging activity on the different antioxidant models used in the study. The maximum inhibition was 96.87±0.76% at 4mg/ml in case of DPPH free radical scavenging activity with IC50 value 0.148mg/ml. The maximum inhibition on LPO activity was 96.10±0.38% at 4mg/ml with IC50 value of 0.265mg/ml. The fish oil also exerted its maximum inhibition 90.21 2.10% on ABTS free radical scavenging activity at 4mg/ml with IC50 value of 0.331...

The prescription pattern of analgesic was investigated for the months of June, July, August 2016 by studying 253 (143 male + 110 female) BHTs of in patients of the orthopaedic department. The data mainly age, sex, diagnosis and line of management available from BHTs was analysed in the form of percentage, average of variable. The generic name cost of treatment per patient and rationality of prescription were evaluated by referring NLEM, CIMS, WHO indicators of drug utilisation. A total of 599 analgesics were prescribed to the patients. The average number of analgesic per prescription was 2.33. The maximum number of patients was in the age group of 41-51 years. Diclofenac was the most commonly prescribed analgesic 152 (26.2%).Only 51 patients received single analgesic and majority of patient received parenteral (45.6% i.m) preparations. Only 9 (1.0%) analgesics from NLEM but no generic name drug was prescribed. And again gastro protective drugs 240 (95.17%) and antibiotics 290 (114%) were frequently prescribed with the analgesics. The average cost of treatment per patient...
