“…Ruhland) is a native plant from the central highlands of Brazil, used to produce highly appreciated handcraft pieces due to its shiny golden-like reflectivity. Beyond the metallic appearance of golden grass vegetal fibers, its ecosystem, chemical composition and pharmacological properties have been investigated by several groups [1,2,3].…”

“…Ruhland, called the golden grass (GG) due to its flower stem or scape that shine like spun gold (Schmidt, Figueiredo, & Scariot, 2007). Their peculiar optical properties are related to the presence of several flavonoids at the surface epidermis of the dry scapes (Berlim et al, 2014). GG stem flavonoids were described as being composed by three flavanones and five flavones (Pacifico et al, 2011).…”

The in vitro antioxidant properties of golden grass (GG), a grass‐like herb ( Syngonanthus nitens ), were investigated by electron paramagnetic resonance (EPR) spectroscopy. We measured the antioxidant capacity of methanolic extracts based on their ability to scavenge 1,1‐diphenyl‐2‐picrylhydrazyl (DPPH) radical. The kinetics of reaction between DPPH and GG extract was determined. This kinetics followed a biexponential decay, and this behavior was attributed to different flavonoids acting together as antioxidants. Isoorientin and luteolin, which are two of the eight flavonoids found in GG extract, were used to investigate kinetics of reaction between DPPH and both the flavonoids acting separately and together. The antioxidant activity of GG extract was determined in terms of the vitamin C equivalent antioxidant capacity (VCEAC). Compared to other well‐known plant‐based antioxidants, such as pulp and peels of fruit and vegetables, S. nitens presented a high antioxidant capacity (VCEAC = 1,485 ± 198 mg/100 g), indicating that it should be regarded as a valuable source of antioxidants and also that it may bestow health benefits when consumed.
