A bioassay-guided isolation of antifungal compounds from an African land race of ginger, Zingiber officinale Roscoe, led to the identification of [6], [8] and [10]-gingerols and [6]-gingerdiol as the main antifungal principles. The compounds were active against 13 human pathogens at concentrations of <1 mg/mL. The gingerol content of the African land race was at least 3 x higher than that of ty...

This study investigated the influence of Trichoderma asperellum on active oxygen production in maize seedlings under saline-alkaline stress conditions. Two maize cultivars were tested: 'Jiangyu 417' ('JY417'), which can tolerate saline-alkaline stress; and, 'Xianyu 335' ('XY335'), which is sensitive to saline-alkaline stress. The seedlings were grown on natural saline-alkaline soil (pH 9.30) in...

Plant of genus Taraxacum known as dandelion have long been used in tradition medicinal. Extracts from dandelion possess anti-influenza virus, anti-fertility and anti-retrovirus activity, antioxidant and hepatoprotective effects. Chicoric acid also known as dicaffeyltartaric acid and belongs to phenylpropanoids is one of the main constituent of T. officinale. The current investigation was conduc...

Oxidative stress due to abnormal production of reactive oxygen molecules (ROM) is believed to be involved in the etiology of toxicities of many xenobiotics. In this study protective effect of Zingiber officinale (ZO) against Aceclofenac (ACE) induced oxidative stress in rat liver was evaluated. Twenty four young wistar rats were divided into four groups as follows: control group, ACE (single do...

Antioxidant and antifungal activity were determined for the essential oil of Alpinia calcarata Roscoe (Zingiberaceae) rhizomes. Its antioxidant properties were investigated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay and thiobarbituric acid reactive substances (TBARS) assay. Butylated hydroxy toluene (BHT) and vitamin E served as positive controls. Antifungal activ...
