“…However, the extraction efficiency was constantly decreased with the further increasing of the ratios of liquid to raw material. The possible reason was that an excess solvent to solid ratio could produce a lot of impurities [33], and cause a significant reduction of TBF content. This indicated that a proper solid–liquid ratio was enough for the extraction.…”

As a new and green solvent, ionic liquids (ILs) have received more attention during the green extraction and separation process for natural medicines. In this paper, IL-ultrasound-assisted extraction (IL-UAE) of total biflavonoids (TBFs) from Selaginella helvetica was firstly developed, and different ILs were employed and compared. Based on single-factor experiment, solid–liquid ratio (1:10–1:14 g/mL), IL concentration (0.6–1.0 mmol/mL), and extract temperature (40–60 °C) were further explored, according to response surface methodology (RSM), with TBF yields as the index. Moreover, antioxidant activity of TBF extract was analyzed by four methods, i.e., 2,2-di(4-tert-octylphenyl)-1-picrylhydrazyl (DPPH) and 2,2′-azinobis-(3-ethylbenzth-iazoline-6-sulphonate (ABTS) free radical scavenging assay, ferric ion reducing power assay, and chelation of ferrous ions assay. The results indicated that [C6mim]PF6 had a high selectivity and efficiency. Moreover, important parameters for the extraction process were investigated and optimized. Through parameter optimization (0.8 mmol/L, 250 W, 40 min, 1:12.7 g/mL, and 47 °C), a yield of 18.69 mg/g biflavonoids was obtained from the extract of S. helvetica. Compared with ethanol-UAE, heat-reflux extraction, Soxhlet extraction, and percolation extraction, IL-UAE could not only obtain higher yield in a shorter time, but also reduce the solvent consumption. In addition, TBF extract showed potential antioxidant activity based on the above four antioxidant methods. In short, IL-UAE was first employed to develop a novel and green extraction method for TBF content, and this experiment provides valuable references for further utilization of S. helvetica.

“…Ekstrak etil asetat dari Selaginella doederleinii Hieron juga berpotensi sebagai sumber bioaktif alami yang mudah didapat dari alam. Aktivitas ekstrak tersebut dikaitkan dengan kandungan fenoliknya, terutama amenoflavon, hinokiflavon dan robustaflavon (Gang et al 2016).…”

“…Zat bioaktif utama ekstrak Selaginella doederleinii Hieron sebagian besar bersifat fenolik. Amentoflavon tidak hanya dapat secara efektif menghambat berbagai macam proliferasi sel tumor tetapi juga menginduksi apoptosis sel tumor dan diferensiasi (Gang et al 2016). Di sisi lain, ekstrak etanol Selaginella doederleinii Hieron menunjukkan aktivitas penghambatan yang berbanding lurus dengan konsentrasi pada sel CNE-1, sementara tidak menunjukkan kecenderungan proporsional yang jelas sehubungan dengan sel C666-1 (Lian et al 2013).…”

Ammonium (NH4+) is a form of ammonia (NH) compound in thewater at low pH. The ammonium can cause poisoning in aquatic life. The purpose of this study was to determine the ammonium concentration in the Ngelom river water sample that flows in the Ngelom village, Taman district, Sidoarjo Regency. The measurement of ammonium concentration in river water samples was carried out using the UV-Vis spectrophotometrymethod with Nessler reagent based on the Nessler reagent reaction (K2HgI4) with ammonium in a base solution which would form a colloidal yellow brown dispersion which absorbance measured at 410 nm. Ammonium absorbance is proportional to the ammonium concentration in the sample. The sampling technique in this study used purposive sampling. Samples were taken at 10 trial points, every 5 meters to the right and left from the center point (Ngelom's River bridge to Maarif Hasyim Latif University). Ammonium concentration was determined in the linear concentration range of 1 – 5 mg/L with a correlation coefficiency value (r) of 0.9615 with limit of detection and limit of quantitation of 0.105 mg/L and 0.352 mg/L, respectively. The results of testing the river water samples showed that the ammonium concentration in 10 samples of river water ranged from 1.61 – 14.68 mg/L. All of the sample was not eligible requirements of the Republic of Indonesia PP No. 82 of 2001 about Water Quality Management and Water Pollution Control.
