Herbs have been widely used for centuries as remedies for diseased human conditions as they have certain phytochemicals of diseases curing nature. The present study explains the antimicrobial (antibacterial & antifungal) potential of dried stem wood of Cissuspallida methanolic extract against bacterial strains of Bacillus subtilis, Klebsiella pneumonia, Staphylococcus aureus, Escherichia coli, Pseudomonas aureginosa, and Aspergillus niger, Aspergillus fumigates, Monoscus purpure fungal strains by Disc diffusion method. The test extract was compared with Ciprofloxacin 5 μg for bacterial organisms and Fluconazole 20 μg for fungal organisms. The extract showed significant antibacterial and antifungal activity which was confirmed by the zone of inhibition...

Peridiopsora mori (Barclay) K.V. Prasad, B.R.D. Yadav & Sullia is one of the fungi which cause brown leaf rust on Mulberry (Morus spp.). Leaf rust disease is one of the major diseases affecting Mulberry (Morus sp.). Synthetic fungicides are commonly applied to reduce disease; however, its improper use may cause residual toxicity on silkworm, environmental and health problems. The extracts of angiosperm medicinal plants were proven by previous workers to possess antimicrobial activities against plant pathogenic fungi. In this study, the antifungal activity of leaf extracts of 5 rarely occurring medicinal plants in Kerala (Mesua ferrea L., Memecylon randerianum S. M. Almeida & M. R. Almeida, Pittosporum tetraspermum Wight & Arn., Symplocos cochinchinensis (Lour.) S. Moor and Syzygium laetum (Buch.-Ham.) Gandhi) were tested against Peridiopsora mori. Antifungal activity of the leaf extract was tested based on the poisoned food technique on potato dextrose agar (PDA). Leaf extracts, 5%, 10%, 15%, 20% and 25% were tested in this study. The results of this study showed that leaf extract of all...

The petroleum (Pet.E), methanol (MeOH) and chloroform (CHCl3) extracts of Rauvolfia canescens (whole plant), Desmodium heterocarpon (whole plant) and Vitex negundo (leaf CHCl3 MeOH and root Pet. E.) have been thoroughly screened through residual film assay against T. castaneum adults and the repellent activity tests were also carried out on the same to find biological activities. The residual film assay offered promising results with remarkable activity against the adult beetles of T. castaneum. A perusal of the data achieved in this experiment clearly showed the presence of insecticidal properties in Rauvolfia canescens (whole plant), Desmodium heterocarpon (whole plant) and Vitex negundo extracts as well as traces of repellent potential. For repellency D. heterocarpon (whole plant /Pet. Ether) extract and V. negundo (leaf /Pet. Ether) extract were weakly active (P <0.05) and R. canescens (whole plant /Pet. Ether) extract and V. negundo (root /Pet. Ether) extract were mildly active (P<0.01); while the rest showed no repellent activity against the adults beetles of T. castaneum. Comprehensive phyto-chemical analyses of the test...

Amino acids are biologically active substances, and a number of them are essential for living beings. Amino acids are found in living cells as well as in body fluids of higher animals, in amounts, which vary according to the tissue and particular amino acid. Amino acid analysis refers to the methodology used to determine the amino acid composition or content of proteins, peptides, and other pharmaceutical preparations. Proteins and peptides are macromolecules consisting of covalently bonded amino acid residues organized as a linear polymer. The sequence of the amino acids in a protein or peptide determines the properties of the molecule. Proteins are considered large molecules that commonly exist as folded structures with a specific conformation, while peptides are smaller and may consist of only a few amino acids. Amino acid analysis can be used to quantify protein and peptides, to determine the identity of proteins or peptides based on their amino acid composition, to support protein and peptide structure analysis, to evaluate fragmentation strategies for peptide mapping, and...

Dementia is a progressive neurological disease of the brain. It demolishes the vital brain cells, causing trouble with memory, thinking, and behavior, brutal enough to affect work, lifelong hobbies, and social life. Recognized factors in dementia include acetylcholine deficiency, free radicals, and inflammation of the brain tissue. Since, the drugs and natural remedies have been prescribed to enhance the memory and protect the memory functioning in dementia people. The traditional herbal medicine, numerous plants have been used to treat age-related cognitive disorders. The use of herbs to treat ailments would later form a large part of Ayurveda. In the first millennium BCE, there emerges in post-Vedic India the traditional medicine system known as Ayurveda, meaning the “complete knowledge for long life”. According to the compendium of Charaka, the Charakasamhita health and disease are not predetermined and life may be prolonged by human effort. The compendium of Suśruta, they defines the purpose of medicine to cure the diseases of the sick, protect the healthy, and to prolong life. Most remarkable...
