hyssopus of­ficinalis l. is one of the most important medicinal plants. medicinal herbs are contaminated by microorganisms. conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

musa sapientum (m.sapientum) commonly known as ‘banana’ is widely used in bangladeshi folk medicine for the treatment of various ailments including diarrhea. hence, the present study was designed to investigate antidiarrheal, antioxidant and antibacterial potential of the methanolic extract of m.sapientum seed (mmss). the extract was studied for antidiarrheal property using castor oil and magne...

Antioxidant and antimicrobial properties of chitosan-sugar complex from six types of sugar (glucose, fructose, lactose, arabinose, maltose, and galactose) were investigated. Antioxidant properties were measured by the DPPH test and a measurement of reducing power. These two methods showed the same profile of antioxidant activity. All chitosan-sugar complexes demonstrated better antioxidant acti...

The purpose of this study was to screen the antioxidant activity of medicinal plant extracts from the Brazilian cerrado, through other methods than the total phenolic content and its correlation with the antioxidant activity. Ethanolic extracts of ten species were evaluated through three antioxidant assays, in vitro, including 2,2-diphenyl-1-picrylhydrazyl (DPPH), total antioxidant activity and...

Euphorbia tirucalli (E. tirucalli) is now widely distributed around the world and is well known as a source of traditional medicine in many countries. This study aimed to utilise response surface methodology (RSM) to optimise ultrasonic-assisted extraction (UAE) conditions for total phenolic compounds (TPC) and antioxidant capacity from E. tirucalli leaf. The results showed that ultrasonic temp...

The antioxidant activities of 70% acetone extract (70% AE) from the hypocotyls of the mangrove plant Kandelia candel and its fractions of petroleum ether (PF), ethyl acetate (EF), water (WF), and the LF (WF fraction further purified through a Sephadex LH-20 column), were investigated by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and ferric reducing/antioxidant power (FRAP)...
