Peanut skin color: a biomarker for total polyphenolic content and antioxidative capacities of peanut cultivars.

Attempts to establish a relationship between peanut skin color (PSC) and total flavonoid (TF) content have produced inconclusive results. This study investigated the potential of PSC as a biomarker for polyphenol content and antioxidant capacity. Peanut cultivars were objectively evaluated for their skin color, total phenolic (TP), flavonoid (TF), proanthocyanidin (TPC) contents and antioxidant capacities (AC).

Developing a national research and development centre in assistive technologies for independent living.

Assistive technology (AT) plays a pivotal role in the lives of people who require assistance with one or more aspects of daily living. Ranging from simple devices such as an augmented fork to complex devices like a power wheelchair with integrated environmental control, AT is a broad term to describe a range of products and services that provide assistance. Historically used in the "disability sector", in recent years AT devices have merged into the ageing sector as more Australians develop an impairment through "age-related disability", creating a larger market for equipment that provides independence or restores lost/reduced functionality.

Effect of frequency and duration of ultrasonication on the extraction efficiency of selected isoflavones and trans-resveratrol from peanuts (Arachis hypogaea).

Plant derived phytochemicals have been the focus of recent research due to their health promoting effects. Previous studies to estimate the levels of these bioactive compounds made use of traditional solvent extraction procedures such as homogenization and soxhlet (reflux) methods. Recently, the ultrasonication technique has been shown to be an efficient non-thermal extraction method.

Comparison of extraction methods for the quantification of selected phytochemicals in peanuts (Arachis hypogaea).

Peanuts have been reported to contain bioactive phytochemicals, particularly isoflavones (genistein, daidzein, and biochanin A) and trans-resveratrol. Currently, limited data are available regarding the levels of these bioactive compounds in peanuts with variations in reported levels. The purpose of this study was to compare four methods of extraction [stirring, sonication, Soxtec, and microwave-assisted sonication (MAS)] for runner peanuts.
