Indonesian local honey contains active compounds that have the potential as an antioxidant and anticancer, primarily as a laryngeal anticancer through the inhibition of HEp-2 cells. This study aims to determine the anticancer activity of several types of honey in Indonesia through the inhibition of HEp-2 cells. Samples used in the form of Trigona, Longan, Rambutan, and Kaliandra honey obtained from honey farmers in Sulawesi and Java, Indonesia. Honey samples extracted by using methanol, then liquids partition was carried out consecutively using n-hexane and ethyl acetate. The cytotoxicity test for HEp-2 cells was carried out using the MTT method (3- (4,5-dimethyl thiazol-2-il) -2,5-diphenyl tetrazolium bromide). The results showed that all honey samples were active against preventing HEp-2 cells with the highest inhibition activity from longan honey with ethyl acetate extract at 65.18% at 100 ppm. Longan honey has decreased HEp-2 cell inhibitory activity after fractionation. Indonesian local honey, namely trigona honey, kaliandra honey, rambutan honey, and longan honey, can be used as a supplementary supplement for patients with laryngeal cancer.

Background : The treatment of some diseases caused by free radicals and pathogenic bacteria usually by using antioxidants and antibiotics. Due to excessive use of antibiotics and other environmental cues, some bacteria are now resistant to certain antibiotics or even to multiple antibiotics. Some Vibrio cholerae bacterial strains are multiresistant to many antibiotics.Objective : The antioxidant and antibacterial activities of Brugueira gymnorrhiza stem extracts against pathogenic bacteria V. cholerae.Method : The B. gymnorrhiza stem was extracted by gradient maceration method. The DPPH method was used to determine the antioxidant activity and the disc diffusion method was used to determine the antibacterial activities. The column chromatography method was used to fractionate the selective extract with the best activity. The LC-MS/MS method was used to identify the compound obtained from the fraction with the best antioxidant and antibacterial activity.Result : Ethyl acetate extract of B. gymnorrhiza stem had the best antibacterial activity with MIC and MBC values of 62.50 mg/L. Ethyl acetate extract also showed the best value of antioxidant activity as indicated by an IC50 value of 255.03 mg/L. The results of fractions test showed that fraction 3 had the best antibacterial and the best antioxidant activities with both the MIC and MBC values of 7.90 mg/L and IC50 value of 348.91 mg/L, respectively.Conclusion : Ethyl acetate extract of B. gymnorrhiza stem has good potential as antioxidant and antibacterial. The compound which is thought as antioxidant and antibacterial from Ethyl acetate extract is 2-Ethyl-4-methyl-1H-imidazole.

This study aimed to investigate phytochemical screening and antioxidant activity of n–hexane, ethyl acetate and ethanol extract from lakoocha leaves. The powdered simplicia was macerated with n–hexane, ethyl acetate and ethanol 96% successively, filtered, then concentrated using rotary evaporator to obtain n–hexane extract, ethyl acetate extract and ethanol extract. Phytochemical screening and antioxidant activity was performed against these extracts. Antioxidant activity was determined by DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging method using ultraviolet-visible spectrophotometer at wavelength of 516 nm after incubated for 60 minutes in dark place. Quercetin was used as positive control. The result of phytochemical screening showed n-hexane extract contains steroid, ethyl acetate extract contain steroid, tannin, glycoside, flavonoid and saponin, whereas ethanol extract contain tannin, glycoside, flavonoid and saponin. The IC50 value of n–hexane, ethyl acetate and ethanol extract was 1062.03±1.42 ppm, 323.18±0.02 ppm and 99.23±0.07 ppm respectively, whereas for quercetin was 2.32±0.01 ppm. This study showed that ethanol extract had antioxidant activity with strong category whereas n-hexane extract and ethyl acetate extract had inactive antioxidant activity with very weak categories.       Keyword: Antioxidant Activity, DPPH, Lakoocha leaf

Boesenbergia pandurata (Roxb.) Schlecht is one of fingerroot plant in ginger family (Zingiberaceae). The rhizomes of the plant contained a lot of secondary metabolites compounds. Therefore, the purpose of the research is to isolate and identify the flavonoid compound from the plant. The rhizomes were extracted with metanol continued by partition using ethyl acetate-water (1:1). The ethyl acetate extract was chromatographed on a column of Si gel (Vacuum Liquid Chromatography and Gravitation Column Chromatography) using n-hexane-ethyl acetate (5:2) as eluents. Further purification by recristalization  using benzene  produced a compound as yellow powder (16 mg) having melting point of 294-295 oC. The spectra of isolated compound were determined by spectroscopic UV-Vis, FT-IR, and GC-MS. Spectrum UV-Vis of the isolated compound showed ultraviolet absorption at λmax (MeOH, nm) 290 and 322; λmax (MeOH+NaOH, nm) 322; λmax (MeOH+AlCl3, nm) 309; λmax (MeOH+AlCl3+HCl, nm) 310; λmax (MeOH+NaOAc, nm) 322 and λmax (MeOH+NaOAc+H3BO3, nm) 290. Its FT-IR spectrum represented a number of absorption lied on νmax (cm-1) : 3142.5; 3012.6; 2893; 2345.3; 1631.7; 1585.4; 1357.8; 1168.8; and 825.5. GC-MS spectrum of the isolated compound exhibited an [M]+ ion peak at m/z = 256 with retention time of  22,579. Based on the results of spectrum analysis it can be concluded that the compound is 5,7-dyhydroxyflavanone.   Keywords: 5,7-dyhydroxyflavanone, Boesenbergia pandurata, ethyl asetat, fingerroot
