The chemical compositions and anti-tumor activities of the petroleum ether fraction (PE), from mushroom Pyropolyporus fomentarius, were studied. Upon gas chromatography-mass spectrometry (GC-MS) analysis, nine major constituents were identified in the fraction. In vitro, the PE showed cytotoxic activity against murine sarcoma S180 (S180) cells in a dose- and time-dependent manner, and the cytot...

Among the diverse variety of red algae, Asparagopsis taxiformis constitutes one of the abundant biomass in the Kollam coast (Southwest coast of India). Therefore, in the present study, A. taxiformis was collected, extracted and fractionated using column chromatography. The individual fractions were evaluated in vitro for their antifouling, anticyanobacterial, piscicidal and crustaceans toxicity...

The aim of the present study was to isolate hepatoprotective component from Urtica dioica Linn. (whole plant) against CCl4-induced hepatotoxicity in-vitro (HepG2 cells) and in-vivo (rats) model. Antioxidant activity of hydro alcoholic extract and its fractions petroleum ether fraction (PEF), ethyl acetate fraction (EAF), n-butanol fraction (NBF) and aqueous fraction (AF) were determined by DPPH...

The study was to evaluate the most effective fraction and subfraction having hypoglycemic activity from the hydro-methanolic (2:3) extract of the fruit of Persea americana Mil. through bioactivity guided investigation in streptozotocin induced diabetic rats. Out of different solvent fractions and subfractions, the effective fraction and subfraction of Persea americana Mill. were subjected to an...

Electrospray ionization (ESI) coupled with high-resolution mass spectrometry (HRMS) is rapidly developing into a powerful tool for the molecular characterization of petroleum fractions. However, occurrence ion–molecule aggregates seriously affects interpretation results. Ion–molecule are not inherent compounds in but they produced during analysis samples by spectrometry. Also, classes same as m...

Nowadays, the thermal and catalytic decomposition of plastic wastes by pyrolysis is one best alternatives to convert these into quality fuel oils, thus replenishing some petroleum resources. This work studied polyethylene film waste from remaining organic fraction on different catalysts under dynamic operating conditions in a batch reactor. These have been characterized through isotherms adsorp...

Background & Aim: Platychaete aucheri (Boiss.) Boissis one of the Persian endemic plants and it belongs to Asteraceae family. The present study was aimed to evaluate the antimicrobial activity of crude methanolic extract and three sub-fractions of the flowering aerial parts of Platychaete aucheri against some gram-positive and gram-negative standard b...

That portion of horse and human serum globulin precipitated by 33 per cent saturation with ammonium sulfate and precipitated on subsequent dialysis was taken as euglobulin; and the fraction precipitated between 33 and 50 per cent saturation and remaining in solution on subsequent dialysis was taken as pseudoglobulin. The sera of rabbits injected with either of these antigens gave precipitation ...
