The skin of dragon fruit, which is accounted for 30-35% of the whole fruit usually thrown away as waste. This study aims to produce a bioactive extract from extraction of dragon fruit skin that is rich in phenolic and pigment compounds then it used as food additives. The variation that was used in this study includes the application of drying as pre-treatment of dragon fruit skin and the extraction methods (maceration and Soxhlet extraction). The obtained extracts were evaluated for the amount of total phenolic compounds and pigments (anthocyanin and betacyanin). Drying of dragon fruit skin was found to yield lower amounts of bioactive materials, which may occur due to the thermal degradation even though a low drying temperature was used. In addition, the maceration method was found to give a higher amount of bioactive materials compared with the Soxhlet method. The extraction with the highest yield of bioactive materials was obtained by the use of fresh dragon fruit skin and maceration for 240 minutes, which gave amounts of anthocyanin, betacyanin, and total phenolic compounds of 0.08, 0.04, dan 0.35 mg/g fresh dragon fruit skin, respectively.","PeriodicalId":13392,"journal":{"name":"Indo.

This research aimed to synthesize AgNPs via bio-reduction method using mangosteen bark extract followed by modification with p-coumaric acid (APK), and evaluating its application detecting melamine. The AgNPs were characterized through ultraviolet-visible absorption spectroscopy (UV-Vis), Fourier transform infrared absorption spectroscopy (FTIR), and X-ray diffraction (XRD). Observation suggested that an increase of incubation time had affected its surface Plasmon resonance trend. Observation of functional group by FTIR showed that carbonyl group (1707 cm-1) suspected from hydroxyl group (3414 cm-1). Further analysis of crystallite via XRD suggested that nanoparticle size at 30 nm estimated using Debye-Scherer, within the form of unit cells is cubic.

This research was a theoritical research using computational chemistry method. The object of research was 21 novel of 1-N-substituted pyrazoline analogues of thiosemicarbazones with their antiamoebic biological activity. The data of research was obtained from quantum chemistry calculation and statistically analysis using Multiple Linear Regression (MLR). The resulting QSAR equation was Log IC50 = 0.869 + (0.081 x TPSA) + (0.018 x HF) + (0.527 x E-HOMO) + (3.378 x E-LUMO) + (-16.938 x Glob) + (0.234 x LogP), with statistic parameters of n = 21; R2 = 0.933; SEE = 0.14558; FHitung/FTabel = 8.607; PRESS = 0.491. This equation was used as a basic for designing and predicting the new antiamoebic compounds of pyrazoline analogues. The design of new compound of two lead compounds with the Topliss resulted 5 of 18 new compounds having theoretical better activity than the lead compound.

Water, sediment, and plant tissue samples were taken at five stations on the Tallo River using a cutting tool and pipe paralon. Sediment was digested with concentrated HNO3 while plants tissue using HNO3 6M, then analyzed by ICP EOS Shimadzu 9000. The results showed the average concentration of Ni inside part of the plant from station 1, 2, 3, 4 and 5 in order following 21.759,03 ppm, 19.056,03 ppm; 36.806,25 ppm; 10.736,66 ppm dan 13.849,25 ppm.

Accumulation of Zn and Ni in Nypa fruticans is grouped as hyperaccumulation plant because the ability of accumulation Ni bigger than 10.000 mg/kg and hyperaccumulation towards Zn because able to accumulate Zn bigger than 10 mg/kg.
