Extracts were obtained from molasses, a byproduct of the sugar industry, via a number of chromatographic steps. Their antioxidant capacity was studied, including the inhibitory effect upon DNA oxidative damage; the phenolic compound profile thereof was ascertained as well. Two extracts exhibited significant antioxidant features, expressed by their capacity to decolorize ABTS radical cation and ...

1,2-bis-(4-Hydroxy-3-methoxyphenyl)-3-hydroxypropan1-one (evafolin B, 1), 1-(4-hydroxy-3-methoxyphenyl)3-hydroxypropan-1-one (2), were isolated for the first time from the genus Schisandra, along with abscisic acid (3), 4-hydroxybenzaldehyde (4), 4-hydroxybenzoic acid (5), methyl 4-hydroxybenzoate (6), methyl 3,4-dihydroxybenzoate (7), and vanillic acid (8). All the compounds were evaluated for...

In this study, milk thistle seeds growing in different areas in Tunisia were cold pressed and the extracted oils were examined for their chemical and antioxidant properties. The major fatty acids were linoleic acid (C18:2) (57.0%, 60.0%, and 60.3% for the milk thistle seed oils native to Bizerte, Zaghouan and Sousse, respectively) and oleic acid (C18:1) (15.5%, 21.5%, and 22.4% for the milk thi...

Zingiber officinale Roscoe. (Family Zingiberaceae) is well known in Asia. The plant is widely cultivated in village gardens in the tropics for its medicinal properties and as a marketable spice in Malaysia. Ginger varieties are rich in physiologically active phenolics and flavonoids with a range of pharmacological activities. Experiments were conducted to determine the feasibility of increasing...

Reverse genetics in Trypanosoma brucei is dependent on the tetracycline inducible system for the precise control over the expression of both genes and dsRNA. Another independent inducible system for trypanosomes would enable the control of the activities of two different genes in the same cell, providing greater experimental sophistication. Here, I describe the development of the vanillic acid ...
