Objectives: Securinega virosa Roxb (Ex Willd) Baill (Euphorbaiceae) root bark has been reportedly used in African traditional medicine in the management of mental illnesses. Previously, the sleep-inducing potential of the crude methanol root bark of Securinega virosa extract and its butanol fraction have been reported. The study aimed to isolate and characterize the bioactive constituent that m...
Salvia chorassanica Bunge is one of the Iranian endemic species of Salvia. There is not any reported literature on S. chorassanica. This study was designed to examine the in-vitro anti-proliferative and proapoptotic effects of the methanol extract of S. chorassanica and its fractions on HeLa cell line. Cells were cultured in EX-CELL®, an animal free medium specially designed for HeLa cell line ...
BACKGROUND Drynaria quercifolia L. (Family- Polypodiaceae) is a fern grows in Bangladesh used in traditional healing by the Garo tribe of Mymensingh district. In the current study, rhizomes and fertile foliage fronds of this plant have been investigated comprehensively to assess their in vitro membrane stabilizing, thrombolytic and antioxidant properties. METHODS Rhizomes and fertile foliage ...
The marine sponge Spongosorites halichondriodes, collected from Mumbai coastal area, was studied for presence of bioactive proteins. Sponge species was identified based on Spicules morphology. Crude protein from the sponge was extracted at the concentration of 5.3 mg/mL in methanol and 3.4 mg/mL in aqueous extract. Six bacterial species (Klebsiella pneumonia, Salmonella typhi, Staphylococcus au...
In the present study, ethyl acetate, butanol and aqueous fractions derived from total methanol extract of Butea monosperma flowers were evaluated for radical scavenging activities using different in vitro models like reducing power assay, scavenging of 2,2 diphenyl-1-picrylhydrazyl (DPPH) radical, nitric oxide radical, superoxide anion radical, hydroxyl radical and inhibition of erythrocyte hem...
The feasibility of using catalytic conversion of methanol to formaldehyde to produce standard amount of substance fractions of formaldehyde was examined. The conversion efficiencies of several catalysts were measured as a function of temperature, balance gas, catalyst bed length, and methanol amount of substance fraction in an effort to identify conditions which yield high and consistent conver...
A morpholine alkaline basic ionic liquid (IL) 1-butyl-3-methyl morpholine hydroxide ([Hnmm]OH) was synthesized and characterized by ¹H NMR and FT-IR. [Hnmm]OH is highly active in catalyzing the synthesis of biodiesel from the reaction of methanol with soybean oil. The influence of the reaction conditions, including the [Hnmm]OH catalyst amount, the molar ratio of methanol to soybean oil, reacti...
The adsorption of the proton-pump inhibitor omeprazole was investigated using RP-LC with chemometric models combined with adsorption isotherm modelling to study the effect of pH and type of organic modifier (i.e., acetonitrile or methanol). The chemometric approach revealed that omeprazole was tailing with methanol and fronting with acetonitrile along with increased fronting at higher pH. The i...

The present investigation was designed to study the effect of an active compound isolated from Justicia wynaadensis against multi drug resistant organisms (MDRO's) associated with diabetic patients. The drug resistant pathogens implicated in wound and urinary tract infection of diabetic patients were isolated and identified by molecular sequencing. Solvent-solvent fractionation of crude methano...
