Antimicrobial Activity against Foodborne Pathogens and Antioxidant Activity of Plant Leaves Traditionally Used as Food Packaging.

In accordance with Thai wisdom, indigenous plant leaves have been used as food packaging to preserve freshness. Many studies have demonstrated that both antioxidant and antimicrobial activities contribute to protecting food from spoilage. Hence, the ethanolic extracts of leaves from selected plants traditionally used as food packaging, including (), (), (), (), (), (), (), and (), were investigated to determine whether they have antioxidant and antimicrobial activities against spoilage microorganisms and foodborne pathogens that might be beneficial for food quality.

Bioassay-Guided Isolation of Two Flavonoids from Derris scandens with Topoisomerase II Poison Activity.

Derris scandens (ROXB.) BENTH. (Fabaceae) is used as an alternative treatment for cancer in Thai traditional medicine.

A topoisomerase II poison screen of ethnomedicinal Thai plants using a yeast cell-based assay.

Ethnopharmacological Relevance: The plants used in this study had previously been identified and used by Thai folk practitioners, who had knowledge of Thai traditional medicine, as alternative treatments for cancer. Investigation into the mechanism of the Topoisomerase II (Top2) poison of these plants may give rise to new drug leads for cancer treatment.

Aim Of The Study: This study aimed to screen ethnomedicinal plants used in Thai traditional medicine for Top2 poison activity using a yeast cell-based assay and also to validate the traditional uses of these plants by examining the Top2 poison activity.

Autoxidation of brain homogenates from various animals as measured by thiobarbituric acid assay.

Introduction: The TBARS assay has been well recognized for determination of lipid peroxidation and oxidative injury in biological samples including brain homogenates. In general, the homogenates are freshly prepared using rat brains as the tissue sources. In this study, we compared the rates of spontaneous lipid peroxidation in brain homogenates obtained from bovine, canine, hen, rat, and swine.
