Abstract
Antioxidant properties of different portions of organic Anoectochilus formosanus hayata with different drying treatments
Highlights
Changes in the global market environment show that the aging population is increasing yearly
The reducing powers of all tested freeze-dried extracts are relatively different when compared to those of the butylated hydroxyanisole (BHA) and α-tocopherol groups at all tested concentrations, we found that all freeze-dried extracts have moderate reducing powers (Figure 1A)
Our results showed that carotenoids positively correlated with the reducing power and DPPH radical scavenging activity in hot air-dried organic A. formosanus
Summary
Changes in the global market environment show that the aging population is increasing yearly. Most consumers agree that a particular food or drink intake can achieve the purpose of promoting health and disease prevention, resulting in the rise of the market of herbal health products used as complementary and alternative medicine (CAM)(CHAUHAN et al, 2013). Reactive Oxygen Species (ROS) are the most abundant free radicals in cells, which are the unavoidable products during normal intracellular metabolism. Phenolics, flavonoids and carotenoids are naturally produced in plants with similar structural basics. These antioxidants can be acquired from the daily diets, belonging to a group of food-derived phytochemicals named as nutraceuticals (PETCHETTI et al, 2007). The genus Anoectochilus (Orchidaceae) is a perennial herb found in many countries including
