Medicinal plants have played an essential role in the development of human culture. Today, contribution industries such as fine chemicals, cosmetics, pharmaceuticals, drugs, and industrial raw materials is remarkable. Recent studies shown that constituents with functional properties effectively treat prevent chronic degenerative diseases. Based on importance medicinal plants, this study aimed t...

In this study, two processes (fermentation and drying) were conducted on Clicanthus Nutans Lindau, which is well-known for its antioxidant activities. The aim of this research is to investigate the effects of these processes towards the Total Phenolic Content (TPC), antioxidant activity and the crude yield of the leaves. For the fermentation process, the fermentation time is varied for 6, 12, 2...

The aim of this study was to examine the possible antioxidant and antidiabetic effects of the aqueous extracts of four Flemingia species in Taiwan. A number of methods were employed for this investigation, including ABTS radical monocation scavenging, FRAP (ferric reducing antioxidant power) method, DPPH (1, 1-diphenyl-2-picrylhydrazyl) radical scavenging, total polyphenol content, total flavon...

Strong antioxidant activity of Pelargonium graveolens is well known. The question addressed in this study was whether different concentrations of exogenous ascorbic acid (AsA) and iron (Fe) were able to influence antioxidant activity and total phenol content (TPC) of geranium. Thus, three levels of Fe (0, 20 and 40 µM) and three levels of AsA (0, 1 and 2 mM) in nutrient solution were c...

The total phenolic content and related total antioxidant capacity of 70 medicinal plant infusions was analyzed. Infusions were prepared in common way in which teas are prepared for human consumption. The total phenolics were measured by Folin–Ciocalteau assay. The total antioxidant capacity was estimated by Ferric Reducing/Antioxidant Power (FRAP) assay. To make practical comparison of relative...

It has been hypothesised that organically grown vegetables are healthier than conventionally produced ones due to a higher content of phytochemicals. However, few data from controlled human studies exist. The aim of the present study was to compare the carotenoid content and antioxidant capacity of organically and conventionally produced carrots under defined conditions. Furthermore, a human in...

A high dietary intake of polyphenols has been associated with a decreased risk of cardiovascular disease and cancer, attributed in part to their antioxidant activity and pro-apoptotic effects. Aquamin is a multi-mineral algal extract that enhances bone mineralization, relieves osteoarthritis, and aids digestion; however, Aquamin has not demonstrated antioxidant activity. In the present study, A...
