The present study aimed at comparing the antioxidant potential of three different samples of Eclipta alba-fresh plant, marketed leaf powder (packaged in sealed containers), and marketed whole plant (sold in open bags). The presence of alkaloids, saponins, triterpenes, terpenoids, tannins, steroids, flavonoids, glycosides was confirmed in all three samples. Fresh plant samples showed a higher antioxidant activity determined using standard ferric reducing antioxidant power (FRAP) assay (3105.16 ± 202.07 AAE/gm. dry weight) and 2, 2-Diphenyl-1-picrylhydrazyl (DPPH) assay (32.37 ± 5.94%). Fresh plant samples also had a higher content of secondary metabolites such as total phenolics and alkaloids as compared to the other two samples. A high correlation was observed between antioxidant capacity and total phenolic content (R2 = 0.997). Loss of antioxidant potential in marketed samples indicates that proper processing and storage are important in ensuring the viability of the raw material of medicinal...

The solubility, dissolution, and gastrointestinal permeability are the prime factors for drug absorption. Rifaximin is a structural analogue of rifamycin that inhibits RNA synthesis by binding to β-subunit of bacterial DNA-dependent RNA polymerase. Rifaximin is a class 1V drug having low solubility and low permeability. My theme of the design is to develop the technological characterization of dosage by converting the drug into nanoparticles and superdisintegrant technology; the drug undergoes solubility and gastrointestinal permeability. By adopting these technologies, it achieves by enhancing the disintegration time of drug when comes in contact with water. Here I would like to promote the range of method development technologies improving the solubility and permeability of class IV drugs in...

Self-medication with OTC drugs is observed in many countries and deserves due concern as it may adversely affect maternal and fetal health. This practice may have an association with socio-demographic factors and knowledge about OTC medicine. A descriptive study was done using a questionnaire that collects information on socio-demographic status, prevalence and knowledge of OTC medicine use among pregnant women. The pregnant women visiting government hospitals in the A sir region were randomly selected. The data collected was analyzed by SPSS software version 20. Moderate level of knowledge about OTC medicine was observed in more than half the sample. More than two-third of the sample was found to have used OTC medicine during their pregnancy. High prevalence of OTC medicine use was found among the unemployed and university-educated sample groups. There was significant association between age of the mother and OTC medicine use, while the association with other socio-demographic variables was not significant. The highest prevalence of OTC medicine use was observed in the sample with a high level...

Andrographolide is a labdane diterpenoid isolated from the leaves and roots of Andrographis paniculata Nees (Acanthaceae). Andrographolide is isolated by various processes and the simple method is the maceration process. It is bitter in taste and used as hepatoprotective, cholinergic, antispasmodic, stomachic, anthelmentic, alterative, blood purifier, and febrifuge. It promotes the secretion of bile in the liver and is used in jaundice, torpid liver, cold and upper respiratory tract infection. It is also used in the treatment of snake bites and is found to be more effective than the anti-snake venom generally used. Hesperidin is a flavanone glycoside isolated from the peels of Citrus sinensis (Rutaceae). Hesperidin plays an important role in plant defense mechanisms. Hesperidin is commonly isolated by two laboratory processes maceration and continuous percolation method. The major pharmacological actions of the hesperidin reported are anti-hyperlipidemic, cardioprotective, antihypertensive, antidiabetic, antioxidant, anti-inflammatory, and antiartherogenic activity. However, what is noteworthy about this paper is highlighting the evidence-based overview on the chemical and physical nature of Andrographolide and Hesperidin along...

The proposed study was to evaluate the in-vitro cytotoxic and antiproliferative activities on prostate cancer cell lines of isocordoin (1) and 2’,4’-dihydroxy-3’-(g,g-dimethylallyl) dihydrochalcone (2), chalcones isolated from roots of Lonchocarpus xuul Lundel, together with four analogues of 1. Isolation of compounds 1 and 2 from L. xuul roots and chemical modification were in accordance with previous works. All compounds were characterized by NMR spectroscopy and mass spectrometry. In-vitro cytotoxic and antiproliferative activities of compounds 1-6 against prostate cancer cell lines PC3, PC3M, DU145, and TRAMPC2, were evaluated using the MTT and sulforhodamine B method, respectively. Additionally, cytotoxic studies with HEK 293 cells were carried out, and a selective index was calculated. From them 2’,4’-dihydroxy-3’-(g,g-dimethylallyl) dihydrochalcone (2), 2´,4´-diacetoxy-3´-(3-methylbut-2-enyl) chalcone (3), 2´-methoxy-3´-(3-methylbut-2-enyl) chalcone (5) together with isocordoin (1) showed the strongest cytotoxic activity on PC3M cell lines in the ranged of 2-3 mg/mL. Isocordoin showed the strongest activity also on TRAMPC2 cell lines (CC50= 1.01 mg/mL). None of the compounds were cytotoxic (CC50 =14 to 667 mg/mL) on HEK293 cell line....
