“…Their peculiar optical properties are related to the presence of several flavonoids at the surface epidermis of the dry scapes (Berlim et al, ). GG stem flavonoids were described as being composed by three flavanones and five flavones (Pacifico et al, ). Nowadays, the extract of S. nitens stems has been studied as a natural product against different Candida species and clinical isolates from patients with vulvovaginal candidiasis (VVC), which results demonstrated that the antifungal properties are effective and it has the ability to inhibit the fungal‐host invasion on human cells (de Freitas Araújo et al, ; dos Santos Ramos et al, ).…”

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.

“…The Eriocaulaceae family is a pantropical and predominantly herbaceous monocotyledonous family, comprising around 1400 species distributed in 10 genera . Some species of the family, such as the Syngonanthus nitens , commonly known as "capim dourado" in Brazil, is an important source of income for the residents of some rural communities in the country who use this plant species in the production of a wide range of traditional handicrafts …”

“…18,19 Dereplication Mass Spectrometry techniques have already been successfully employed towards identifying secondary metabolites including flavonoids and naphthopyranones in the Eriocaulaceae family species. 5,16 By virtue of that, we decided to use a dereplication approach based on Liquid Chromatography coupled to High-Resolution Mass Spectrometry (HPLC/ESI-HRMS/MS) as an analytical tool for the rapid screening and structural determination, with analytical sensitivity and specificity, of the main secondary metabolites present in the aerial parts of A. divaricatus (capitula, scapes and leaves). Furthermore, we also carried out chromatographic fractionation of the crude methanolic extract aiming at isolating new compounds of A. divaricatus, which were fully characterized by Nuclear Magnetic Resonance (NMR) and Mass Spectrometry.…”

The HRMS technique enabled us to identify several classes of compounds. In addition, saponins were identified for the first time in plants belonging to the Eriocaulaceae family. Thus, the essential contribution of this work lies in the new elements it brings to the taxonomic discussion which the Actinocephalus genus as a distinct genus of the Paepalanthus. The results obtained show that the methanolic extract of the capitula could be a promising source of bioactive fractions and/or compounds that may contribute towards breast cancer treatment.

The screening for antimicrobial activity of twenty five endophytic fungi isolated from the aerial parts of Paepalanthus chiquitensis (Eriocaulaceae) was assayed against the bacteria Grampositive Staphylococcus aureus, Gram-negative Escherichia coli and Salmonella setubal, and the yeast fluconazole-resistant Candida albicans. The ethyl acetate extract produced by Fusarium fujikuroi was the most bioactive and this fungus was chosen for the chemical study, affording the isolation of an alkaloid 2-(4-butylpicolinamide) acetic acid and three known metabolites: fusaric acid, indole acetic acid and the sesterterpene terpestacin. The minimal inhibitory concentration of the extract and of fusaric acid and indole acetic acid for all the tested microorganisms had values from 125 to 1000 µg mL -1 .
