Potentilla anserina (Rosaceae) is a traditional medicinal plant in India, and it is available throughout the Northern hemisphere. This study was intended to evaluate the antinociceptive activity of methanolic extract of Potentilla anserina in acetic acid-induced writhing test in mice and Eddy’s Hot Plate method in Albino rats at the dose level of 75, 150 and 300 mg/kg p.o and the study was compared with the standard drug Indomethacin 10 mg/kg. The data were expressed as mean ± S.E.M. The statistical analysis was done using ANOVA followed by Dunnett‟s post hock test. The methanolic extract of Potentilla anserina showed significant antinociceptive activity in the acetic acid-induced writhing method the PAME (75, 150, 300 mg/kg, p.o) 1hr before a pain stimulus significantly reduced the nociceptive response. In the hot plate method, there was no significant difference in nociceptive behavior. The antinociceptive activity could be associated with the presence of several flavonoid-based bioactive compounds and their synergistic action with non-volatile bioactive...

Background: The standard management of operable LABC is by initial modified radical mastectomy. Because of the high risk of metastasis, systemic therapy is involved as an additional integral part of treatment. The postmastectomy radiation is given to reduce the high risk (20-40%) of loco-regional relapse following adjuvant systemic therapy. The loco-regional control ranges from 85% to 90% for 10 years survival of 40% to 50% for operable stage III breast cancer treated through modified radical mastectomy, adjuvant systemic therapy, and post-mastectomy radiation. Objective: The Aim and objective of the study were to compare the loco-regional response in two arms for 4 weeks after completion of radiation therapy and at the end of six months of follow up and to compare acute and chronic toxicities in the two arms. Methods: In this study, patients with histopathologically established breast cancer were selected from out-patient Department of J. K. Cancer Institute Kanpur and were placed randomly into two different arms. Arm A delivered “40 Gy in 15 fractions over 3 weeks,” and...

Incidence of fungal infections is increasing at an alarming rate, presenting an enormous challenge to healthcare professionals. Despite advances in preventive, diagnostic, and therapeutic interventions, the invasive fungal infection causes significant morbidity and mortality in immunocompromised patients. An effective alternative to conventional synthetic antifungal agents can be the use of medicines from natural sources for treatment of fungal infections. The present study is based on a comparative evaluation of preliminary phytochemical screening and in-vitro antimicrobial activity of petroleum ether and ethanolic extracts of Cassia tora seeds and leaves. Phytochemical screening revealed the presence of carbohydrates in all four extracts while anthraquinones were found in ethanolic extract of leaves and seeds. The in-vitro antimicrobial assay was performed by agar well diffusion method. Each of the extracts was screened for antimicrobial activity against Candida albicans, Staphylococcus aureus, and Escherichia coli. Ethanolic extract of leaves showed significant antimicrobial activity. The MIC of ethanolic extract of leaves was found to be 100 mg/ml, 75 mg/ml and 50 mg/ml against Candida albicans, Staphylococcus aureus, and...

Calotropis procera plant belongs to the Asclepiadaceae family. It is prescribed to treat bronchitis, asthma, cough, infections, cancer, ascites, intestinal worms, cutaneous diseases, eczema, leprosy and also aid to stimulate the immune system. The leaves of C. procera were investigated for their phytochemical and anti-microbial activity. Chemical screening of leaves ethanolic extract exhibited to contain active compounds like alkaloids, terpenoids, flavonoids, saponins, and reducing sugar. The antibacterial activity of C. procera leaves against four different bacteria revealed that the ethanolic extracts could kill only Staphylococcus aureus and Basillus subtilis, but more resisted by Pseudomonas sp., and Escherichia coli compare to the standard antibiotic streptomycin. GC-MS analysis of the ethanolic extracts indicated that the highest percentage in 100% ethanolic leaves extract belongs to camphene 6.22%, thebaine 7.59% dodecanoic acid 19.15%, and linolenic acid ethyl ester 14.87%, while the highest percentage in 70% ethanolic leaves extract belongs to hexa-hydro-farnesol 9.87%, gamolenic acid 12.71%, and linolenic acid ethyl ester 6.83%. This is the first phytochemical, and antibacterial study on C. procera leaves...

The extensive study on O – methylated flavonoids reveals that substitution with methyl group enhances the radical scavenging behavior in certain compounds. Due to potential applications of C-glycosides in metabolic engineering, methylation in these flavonoids needs to be analyzed in both theoretical and experimental levels for their radical scavenging behavior. In this work naturally occurring C- glycosyl flavonoid apigenin 8-C-glucoside (vitexin) is theoretically simulated by substituting the C4′, C5 and C7 hydroxyl positions with methoxy unit and studied with the aid of density functional theory (DFT) for radical scavenging behavior. Structural stability is attained through B3LYP/6-311G(d,p) theory using Gaussian 03 package which provided the stable conformer for the studied compound without imaginary frequency. Structural activity is analyzed with the support of parameters like kinetic energy (temperature independent), HOMO-LUMO, molecular descriptors, Mulliken charge density analysis and compared with vitexin. Combined investigation of the parameters above revealed the superiority of phenyl hydroxyl vitexin over phenyl methoxy vitexin for radical scavenging activity unlike its O methylated...
