Comparison of antifungal activity of essential oils from different plants against three fungi.

The antifungal activity of plant essential oils (EOs) extracted by steam distillation from seven different species (Cinnamon, Anise, Clove, Citronella, Peppermint, Pepper, and Camphor) was investigated. Three common fungi were isolated from moldy wheat bread, which were identified as Aspergillus niger, A. oryzae, and A.

Identification and expression profiles of twenty-six glutathione S-transferase genes from rice weevil, Sitophilus oryzae (Coleoptera: Curculionidae).

The rice weevil, Sitophilus oryzae, is one of the most destructive pests in stored cereals products. In this study, 26 cDNAs encoding glutathione S-transferases (GSTs) were sequenced and characterized in S. oryzae.

Effects of different chemical modifications on the antibacterial activities of polysaccharides sequentially extracted from peony seed dreg.

The peony seed dreg polysaccharide (PSDPs) fractions and their modified derivatives were examined for their antibacterial potential. PSDPs along with their derivatives exhibited appreciable antibacterial activity against both Gram-positive (B. subtilis and S.

Effects of different chemical modifications on the antioxidant activities of polysaccharides sequentially extracted from peony seed dreg.

Four types of sequentially extracted peony seed dreg polysaccharides (PSDPs) fractions were modified through sulfation, phosphorylation and carboxymethylation and studied for their in vitro antioxidant characteristics. The modified derivatives showed decreased sugar and protein content, while uronic acid content was elevated as compared to native (un-modified) polysaccharides. Further, modified derivatives shared the similar maximum absorption peaks indicating their homogeneous nature.
