A series of discrete mononuclear lanthanide(III) complexes of H2L1 [Ln(H2L1)(NO3)2]NO3.nH2O (Ln = La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Y; n = 1 for Ce; n = 2 for La, Sm, Gd and Y; n = 3 for Pr, Nd, Eu, and Tb) have been prepared by the condensation of Schiff-bases with the precursor compounds namely, 2,6-diformyl-4-methylphenol, 1,5-diamino-3-azamethypentane and 4,5-dimethyl-1,2-phenylenediamine. All the mononuclear complexes have been prepared in situ by the step-wise condensation from the precursor compounds. The phenolate oxygen atom of the nucleating ligand behaves as a bridging group between the metal. The complexes have been characterized by elemental analysis, IR, UV-Visible, ESI mass spectra and magnetic studies. The yield of these complexes increases from lighter lanthanides to heavier lanthanides. The fluorescence studies were carried out for europium and terbium complexes. The results of elemental analysis of the complexes are in good agreement with the theoretical values. The complexes are soluble in methanol, chloroform, DMF, DMSO, and CH3CN. Conductivity studies reveal that all the complexes are 1:1...

Snakebite is an important cause of morbidity and mortality and is one of the major health problems in India. Russell’s viper (Daboia russelli) appears to be the commonest cause of fatal snakebite in many Asian countries and especially in the Indian subcontinent. Intravenous administration of anti venom serum neutralizes the systemic actions, but it is of little effect on the reversal of local symptoms and often induces adverse reactions, a context that drives the search for complementary treatments for snakebite accidents. Plant extracts with a range of antiophidian activities constitute an excellent alternative. The methanolic extracts of seeds of Pongamia pinnata, fruits of Piper longum and Sapindus laurifolius and leaves of Adhatoda zeylanica were tested for the snake venom neutralizing capacity using in vitro methods. The venom of Daboia russelii (Russell’s viper) was used to evaluate the antivenom activity of these extracts individually and in combinations. The parameters assessed were the neutralization of procoagulant activity, proteolytic activity and phospholipase A2 activity. All the extracts studied exhibited significant activity in...

In the present investigation phenolic contents and antioxidant potential of Barleria prionitis L. leaf and stem extracts were analyzed by in vitro antioxidant assays and RP-HPLC method. The results indicated that high amount of total phenolics were present in acetone extracts of leaf (20.22±0.57 mg of GAE/g) and stem (21.19±1.25 mg of GAE/g). Highest flavonoid content was observed in ethanolic (44.23±2.82 mg of RE/g) and acetone extracts (44.94±0.85 mg of RE/g) of leaf, while stem extracts were poor in flavonoid contents. RP-HPLC method for determination of specific phenolic compounds was reported for the first time in B. prionitis L. Out of the phenolic compounds tested, Gallic acid was most common and more abundantly present in both leaf and stem of B. prionitis L. Aqueous extract of leaf showed highest extraction capacity for Gallic acid (211.70 μg/g) and Catechol (112.57 μg/g), while Caffeic acid (37.74 μg/g) and p-Coumaric acid (48.66 μg/g) were highest in methanolic extract. The present study indicated strong influence of extraction solvents and plant parts on antioxidant...

Objective: Schizophrenia is a psychiatric disorders rapidly rising in India. There are numerous classes of antipsychotic agents available. It is important to find out which are the most frequently prescribed antipsychotics in population subsets of various regions of the country. Similarly, it is also important to do apharmacoeconomic evaluation of such treatment. Thus the primary objective of the study was to observe the prescribing pattern and evaluate the average cost of antipsychotics used. Methods: The drug prescribing pattern was noted from the Psychiatry OPD of Modern Institute of Medical Science, Indore and cost analysis performed for the drugs used. The data from OPD card of patients was obtained in a structured study proforma. Results: In 6 months, 304 cases reviewed out of which 158(52%) cases were of Schizophrenia. The Female to Male ratio of patients was 1.24. The average drugs per prescription were 3.17.68% of patients were on monotherapy. Out of total antipsychotics prescribed, 35.39% were Typical and 64.61% were Atypical Antipsychotics. Most commonly prescribed antipsychotic drugs were Olanzapine...

Maytenus emarginatus Willd. Celeastraceae, popularly known as “Kankeri or kankero”, is a Thorny staff evergreen tree that is rich in various chemical constituents that determine the medicinal potential of this species. Diabetes mellitus is a disease that is affecting major population of the world. This study aimed to evaluate the antihyperglycaemic activity of the hydroalcoholic extract of the leaves of Maytenus emarginatus plant which is widely found in dry and arid regions of India mainly in Rajasthan. The hydroalcholic extract of the leaves of M. emarginata (250 and 500 mg/kg/day) were administered orally to streptozotocin-induced diabetic rats (n = 6/group) for 21 days. Changes in body weight, food and water intake, biochemical markers, fasting glucose levels and oral glucose tolerance test were evaluated. The results showed that the M. emarginatus dried extract (250 and 500 mg/kg) reduced significantly the level of blood glucose comparable to glibenclamide (10mg/kg) throughout the evaluation period and improved metabolic status of the animals and ameliorate the oral tolerance glucose test. Thus, we conclude that...
