Mental disorders are commonly occurring and often seriously impairing in many countries throughout the world. The total number of people suffering from anxiety or depression amount to 615 million, Close to 10% of the world’s population is affected. Chrysanthemum indicum is an ancient herbal medicine used as an anti-arthritic, anti-inflammatory and anti-anxiety in many Asian countries. The elevated plus-maze (EPM) and open field test has been most familiar tool in the investigation of the neurochemical transmission basis of anxiety, for testing anxiolytic drugs. The anxiolytic activities of Ethanolic and Chloroform extracts of Chrysanthemum indicum Linn flowers were evaluated using the elevated plus-maze (EPM) and Open field. The ethanolic extract results are suggestive of anxiolytic activity in dosages around 250 and 500 mg/kg, as expressed by elevation of the time spent on the open arms in the plus-maze; a decrease of freezing and increase of deambulation in the open field...

The aim of the present studies is to evaluate the cytotoxic effects of newly formulated polymeric nanoparticles (ETP NP’s) of Escitalopram oxalate (ETP) on NB41A3 cell lines. They were made by ionic gelation method with particle size range between 60 – 115nm, showing spherical morphology. Moreover, zeta potential of the same was recorded as -1.89 ± 0.052 mV and its permeability release showed 98.45 ± 1.82 % in 24 hour. The cytotoxicity evaluation of the optimized formulation (A3) included qualitative method of cell morphology (microscopic and DAPI staining evaluation) and quantitative colorimetric assays like – neutral red (NRU), MTT and LDH. The results suggested that, in presence of ETP, there was a remarkable decrease in cell count whereas; ETP NP’s showed lesser cytotoxicity. performed. Further, in NRU membrane integrity was assessed and it showed 95.2 ± 0.83 % and 72.2 ± 0.56% of cell viability in ETP NP’s and ETP pure respectively. However, MTT assay summed up the cell viability up to 93.6 ± 0.68 % in ETP NP’s...

The excessive exploitation of medicinal plants during recent years raises the issues regarding their quality, safety and efficacy. In this respect, there has been a rapid increase in the standardization of medicinal plants with therapeutic potential. In spite of the new techniques, identification and evaluation of plant drugs pharmacognostic study is more cheap and reliable. Abrus precatorius L. of family Fabaceae is native to India and is locally known as Rati. It is widely employed in traditional medicinal systems. The present investigation deals with the macroscopic and microscopic evaluation of the seeds of this species to record the parameters of diagnostic value. Macroscopic studies comprised of shape, size, taste, colour, odour etc. Microscopic studies were done by using trinocular microscope. Anatomy of the seed was studied by taking transverse sections. Such information will be used for further therapeutical and pharmacological evaluation of the species and will also help in maintaining the quality and purity of sample. Moreover, the study would also serve as a valuable tool in drug identification...

Medicinal plants used in traditional medicine and various cultures can be valuable resources for discovering new drugs. This review was conducted to report Iranian medicinal plants effective on sexual dysfunction (sexual desire disorders, erectile dysfunction, and premature ejaculation). To conduct this systematic review, the search terms Sexual*, Aphrodisiacs, Erectile, and Libido* combined with Medicinal plants, Herb*, and Phyto* were used to retrieve relevant publications from the databases International Scientific Institute, PubMed, Scopus, and EBSCO. Tribulus terrestris, Rosa damascena, Crocus sativus L., rosmarinic acid, and crocin are a number of medicinal plants and their derivatives that have libido-boosting properties. C. sativus, Zingiber officinale, and Peganum harmala are some of the plants that exert therapeutic effects on erectile dysfunction. Boswellia serrata and Lavandula angustifolia are two plants used to treat premature ejaculation. Medicinal plants that are used to treat sexual dysfunctions in Iran can help to improve sexual desire disorders, erectile dysfunction, and premature ejaculation through certain mechanisms such as affecting the cerebral neurotransmitters and sex cells, increasing physical strength, causing...

Solubilization is depends on solute-solvent interaction, dissociation of solute in solvent into ionic form, temperature, pressure, hydrogen bonding, dielectric constant, polarity and non-polarity of substance, pH, etc. Partition coefficient was determined in two immiscible solvents in aqueous and organic layer. Benzoic acid was selected for present study for its solubilization in different pH buffer solutions (acidic, neutral and basic) and for partition coefficient study at room temperature. Solubility of benzoic acid in different pH buffer solutions was analyzed by titration method. Most common two immiscible solvent such as water as hydrophilic solvent and benzene as hydrophobic solvent were selected for partition coefficient study. The drug benzoic acid was partitioned between these solvent by shake-flask method and analyzed the concentration of drug in both solvents by acid-base titration method. Solubility and distribution of benzoic acid between benzene-buffer solution of pH 4.0, 7.0, 9.0 and distilled water have been determined. It was observed that the benzoic acid remains un-dissociated monomer molecular form in aqueous layer and as dimer associated form in...
