Introduction: Lung cancer remains the leading cause of cancer death worldwide, so research is ongoing to discover new therapeutics, such as plant-derived bioactive compounds. For example, Sinensetin, a plant-derived polymethoxylated flavonoid, and Imperatorin, a natural furanocoumarin, have anti-cancer properties. This study assessed the effects of sinensetin and imperatorin separately and in combination on A-549 lung cancer cell viability. Method: The A-549 lung cancer cell line was treated with sinensetin (60 μM), imperatorin (30 M), or a combination of both compounds (Sin:Imp 30:30 μM; 50:50 μM and 60:30 μM) for 48 hours. Cell viability was then assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) assay and apoptosis was determined using fluorescein isothiocyanate (FITC) Annexin-V/Propidium iodide staining. Results: The combination treatment of Sin:Imp 50:50 and Sin:Imp 60:30 μM reduced cell viability more than the individual treatment of sinensetin and imperatorin, with the lowest cell viability observed for the combination treatment of Sin:Imp 50:50 μM. Likewise, the combination treatment of Sin:Imp 50:50 μM induced the most apoptosis compared to individual treatment. Conclusion: Sinensetin and imperatorin can decrease A-549 lung cancer cell viability and are potent apoptotic inducers, especially when they are used in combination, therefore they are potential lung cancer therapeutics.

Introduction: Imperata cylindrica, commonly known as cogon grass, is currently widely distributed and used as a medicinal plant. The major compounds that have been isolated and identified are polyphenols and flavonoids, which have many biological activities such as antioxidant, and anticancer. Polyphenols and flavonoids are mostly found in the roots and leaves. This study aimed to perform phytochemical screening on I. cylindrica root ethanol extract from Sragen, Central Java, Indonesia and determine the total polyphenol, flavonoid, antioxidant activity and quantify Sinensetin and Imperatorin contents of the extract. Method: Quantification of all parameters were measured using visible spectrophotometric methods. Total polyphenol, total flavonoid contents, as well as antioxidant activity were measured using Folin-Ciocalteu reagent, aluminum chloride reagent, and 1,1-diphenyl-2-picrylhydrazyl, respectively, and quantification of Sinensetin and Imperatorin were measured using High Performance Liquid Chromatography. Results: I cylindrica root ethanol extract had a total polyphenol content of 1.109\% gallic acid equivalent, total flavonoid content of 0.1\% quercetin equivalent, and antioxidant activity IC50 824.30 μg/ml. Sinensetin and Imperatorin were also identified in Fractions 1 to 11 with concentrations of 0.0157 and 0.0178 mg/kg extract, respectively. Conclusion: I. cylindrica root ethanol extract from Sragen had active phytochemical compounds of polyphenols, flavonoids, and antioxidants as well as Sinensetin and Imperatorin.

Introduction: Imperata cylindrica root methanol extract harvested from Kendari had anti-hypertensive activity stated in a study on hypertension rat models at the doses 60 and 90 mg/kg-bw. The extract also contained phenolic compound 1.53\% (GAE) and flavonoid 1.17\% (QE) and had antioxidant activity IC50 0.32 mg/mL. Aim of the study was to determine the active secondary metabolites in the extract. Materials and Method: Sinensetin and imperatorin in the extract were separated on silica gel 60 column, eluted with a gradient eluent system as follows (1) n-hexane- ethyl acetate (3:7); (2) n-hexane {\textendash} ethyl acetate (2:8); (3) ethyl acetate -MeOH (8:2), and (4) methanol. Imperatorin and sinensetin in fractions were identified and quantified by HPLC method with column LiChroCART 250-4,6 RP 18E, isocratic mobile phases with the composition of mixture as follows, 0.1\% formic acid, acetonitrile and methanol (40:50:10) respectively, and at temperature 400 C. The total tannin was determined by spectrophotometry method with Fe(III) chloride and 1.10-Phenanthroline at wave length 510 nm. Results: Imperatorin and sinensetin were identified in fractions 5 to 9. The concentrations of sinensetin and imperatorin in Imperata cylindrica root methanol extract were of 32.348 and 37.014 mg/kg extract, respectively. The total tannin content was 1.06 \% (w/w) (TAE). Conclusion: Imperata cylindrica root methanol extract from Kendari had active phytoconstituents, namely sinensetin, imperatorin, and tannin.
