Barberry fruit is consumed in different forms including dried fruit, juice, jam and marmalade in Iran. This fruit is also used as a food additive (flavoring and colorant) in soup and rice dishes. In present study, antioxidant activities of acetone, ethanol and water (infusion and decoction) extracts of barberry (Berberis vulgaris) fruit were investigated using 2,2-azinobis-3-ethylbenzo...

Decryptification of acid phosphatase in Geotrichum sp. arthrospores was accomplished using acetone or dimethyl sulfoxide treatment. Both dimethyl sulfoxide and acetone irreversibly destroyed the integrity of the spore membranes without solubilizing acid phosphatase.

BACKGROUND Canarium odontophyllum Miq. is a plant species widely known as 'dabai' and can be vastly found in Sarawak. The aim of this study was to assess the cytotoxic and genotoxic effect of extracts from stem bark of C. odontophyllum against HCT 116 human colorectal cancer cell line. METHOD The IC50 values of the aqueous, methanol, and acetone extracts against HCT 116 cells as well as the a...

Infrared spectroscopy of biological cell monolayers grown on surfaces is a poorly developed field. This is unfortunate because these monolayers have potential as biological sensors. Here we have used infrared microscopy, in both transmission and transflection geometries, to study air-dried Vero cell monolayers. Using both methods allows one to distinguish sampling artefactual features from real...

Acetone is an important solvent and widely used in the synthesis of drugs and polymers. Currently, acetone is mainly generated by the Cumene Process, which employs benzene and propylene as fossil raw materials. Phenol is a co-product of this synthesis. However, this ketone can be generated from ethanol (a renewable feedstock) in one-step. The aim of this work is to describe the influence of phy...

This study examines a water-based system, coupling an adsorber and a photoreactor, for regeneration of granular activated carbon (GAC) saturated with acetone and isopropyl alcohol (IPA). Through water recirculation the regeneration reaction was operated in both intermittent and continuous ultraviolet illumination modes. With a periodic dosage of hydrogen peroxide not only was regeneration effic...

Imaging scheme based on Acetone-OH simultaneous PLIF (Planer Laser-Induced Fluorescence) is applied for diagnostics of reactive zone over the premixed flames and the reactive zone imaging are demonstrated for turbulent premixed flame conditions. In the present study, visualization of reactive zone is brought by simultaneous measurement of unburned zone through acetone (seeded into the fuel flow...

A novel acetone extract from cottonseed oil sludge was firstly discovered against plant viruses including Tobacco mosaic virus (TMV), Rice stripe virus (RSV) and Southern rice black streaked dwarf virus (SRBSDV). Gossypol and β-sitosterol separated from the acetone extract were tested for their effects on anti-TMV and analysed by nuclear magnetic resonance (NMR) assay. In vivo and field trials ...

Fifteen plant species were collected from the Nelspruit Botanical Garden based on a list of plants provided by Phytomedicine Programme at the University of Pretoria and their ethnopharmacological information. Hexane, dichloromethane (DCM), acetone and methanolic extracts were screened for antimycobacterial activity against Mycobacterium smegmatis. The acetone extract of Milletia stulhimannii wa...

People may develop a headache, fatigue and even narcosis when the concentration of acetone in air is higher than 10,000 ppm. Hence, detecting and measuring acetone concentrations in the workplace or human body are necessary for our safety and health. Gas sensors play vital role in detecting, monitoring and controlling the presence of hazardous and poisonous gases in the atmosphere at very low c...
