Scurrula parasitica L. is a parasitic plant, traditionally used by the people of Mizoram for the treatment of various diseases, and locally called Vatesawi. The bioassay-guided purification of the methanol extract of the leaves of Scurrula parasitica L. led to the isolation of 2-(3, 4-dihydroxy phenyl)-3,5,7-trihydroxy-4H-Chromen-4-one. Quercetin is a flavonol that belongs to one of the subclasses of flavonoids. For separation and purification of compounds, thin layer chromatography and column chromatography were performed using the plant extract. Then identification was done by high-performance liquid chromatography (HPLC) with mass spectral analysis, and confirmation of the isolated compound was performed with thin layer chromatography. The results showed that the solvent system of ethyl acetate 7: chloroform 3 had accurate separation, and the fraction no-200 from column chromatography was processed for identification of the compound. Structures were established with the mass spectrum and confirmation of the compound was done by comparing with standard quercetin, and both appeared at the same wavelength of 254nm (RT...

Depression is a collective term used for the mental condition characterized by loss of interest, inability to concentrate, eat or sleep, reduced energy levels, together with reduced self-esteem. To date, the medicines available are often associated with several adverse conditions and fail to treat comorbidities it entails. Phosphodiesterase (especially its inhibitors) are recently gaining attention owing to their benefits on the central nervous system. With this background, the present study aimed to evaluate the anti-depressant activity of Roflumilast using albino mice. 8 groups of 6 albino mice of either sex were randomly selected, 4 groups were allocated for forced swim test (FST) and 4 for tail suspension test (TST). Group 1 – Normal saline (10ml/kg), Group 2 -Imipramine (20mg/kg), Group 3 T1 – Roflumilast (0.06mg/kg), Group 4 T2 – Roflumilast (0.06mg/kg) and Imipramine (10 mg/kg). Drugs were administered orally for 14 days. The acute study was done on day 1 and the chronic study on day 14. Percentage reduction of immobility period during FST by Imipramine, T1 and T2 are 51.9%, 37.5%,...

The development of anti-microbial agents, microorganisms that have acquired resistance to drugs through a variety of mechanisms, have emerged and continue to plague human beings. Since, the use of anti-microbial drugs has selected drug-resistant bacteria, the proper use of currently available anti-microbial drugs and efforts to minimize the transmission and spread of resistant bacteria through appropriate infection control would be the first step in resolving the issue of resistant organisms. Synthesize and characterize some metal complexes with Schiff base derived from substituted salicylaldehyde and amino acids by an efficient methodology. The synthesized compounds were evaluated for their in-vitro anti-microbial activity. Synthesized compounds were examined for Anti-bacterial activity using the disc diffusion method and antifungal activity using cup plate method. The bacterial strains of Escherichia coli [Gram negative] MTCC – 443, Staphyloco ccusaureus [Gram positive] MTCC – 96, Bacillus subtilis, and Salmonella typhi using norfloxacin as standard. The fungal strain of Candida albicans with fluconazole was used as standard. In-vitro anti-microbial data represent the cobalt-containing metal complex were most active...

Medical prescription carefully conceived is essential to provide effective health care to the patient. It is a medicolegal document that should be legible, clear and complete. However, several studies have shown that prescription errors remain common worldwide, particularly in low-income countries the such Democratic Republic of Congo. This study aimed to explore the completeness of medical prescriptions in Southeast Kinshasa community pharmacies and to propose possible solutions. The study was conducted from January to Mai 2020. A total of 720 prescriptions were randomly sampled and assessed for key elements following WHO guidelines. Prescriptions analysis was performed using the descriptive statistics: percentage, mean and frequency. Prescribers, patients and drug details were recorded at an average rate of 54.41% (1.94-98.89%), 38.92% (0-94.17%), 38.23% (14.87-90.22%) and 59.28% (11.67-99.4%), 27.68% (3.05-90.55%), 38.71% (15.88-98.39%) from Ngaba and Lemba community pharmacies, respectively. Only 19.63% and 11.15% of drugs were written in generic names, respectively. The average drug number by prescription was 4.37 (1-10) and 3.29 (1-9), respectively. Our study revealed that prescription errors are a...

A new isocratic HPLC method based on reverse phase separation has been developed for simultaneous estimation of Dextromethorphan hydrobromide (DMP), Triprolidine hydrochloride (TPN), and Phenylephrine hydrochloride (PHE) in their mixed liquid dosage form. The chromatographic separation was accomplished on Agilent TC-C18 (250 x 4.6 mm, 5× m) column with a flow rate of 1 ml/min, UV detection (271 nm). Mobile phase consisting of 5 g DOSS, methanol, tetrahydrofuran, and water in the ratio of (70:10:20) pH 4.0 adjusted by acetic acid. The method was found to be selective for PHE, TPN, and DMP with retention time 4.7 min, 5.9 min, and 6.9 min, respectively. The linearity was established over the concentration range of 160-240 mcg/ml, 40-60 mcg/ml and 320-480 mcg/ml for PHE, TPN and DMP, respectively. Limit of detection and Limit of quantification for PHE was found to be 37.87 μg/ml, and 114.77 μg/ml, respectively, for TPN was found to be 10.19 μg/ml and 30.89 μg/ml, respectively and for DMP was found to be 57.50μg/ml and 174.26 μg/ml, respectively....
