BACKGROUND The aim of the present study was to evaluate the physical, biochemical and antioxidant properties of four Malaysian monofloral types of honey (gelam, longan, rubber tree and sourwood honeys) compared to manuka honey. Several physical parameters of honey, such as pH, moisture content, electrical conductivity (EC), total dissolved solids (TDS), color intensity, total sugar and sucrose ...

The antioxidant and antinociceptive activities of Citrus limon essential oil (EO) were assessed in mice or in vitro tests. EO possesses a strong antioxidant potential according to the scavenging assays. Moreover, it presented scavenger activity against all in vitro tests. Orally, EO (50, 100, and 150  mg/kg) significantly reduced the number of writhes, and, at highest doses, it reduced the numb...

The methanol extract of Salvia macrochlamys Boiss. and Kotschy was fractionated on a silica gel column to yield a group of terpenic compounds. After separation and cleaning, seven known and three new terpenoid compounds were isolated, and their structures were elucidated by spectroscopic methods, including intensive NMR and MS studies. The crude extract was tested in five different systems for ...

The aim of the current study was to evaluate Morinda citrifolia (noni) seed extract, a food ingredient, for potential toxicity and antioxidant activity. Nitrates, nitrites, phytic acid, oxalic acid, as well as aflatoxins B1, B2, G1 and G2 were not detected in the extract. The extract was also non-cytoxic (LC50 > 1 mg/mL) in the 24 and 40 h brine shrimp toxicity test. There were no symptoms of t...
