Abstract: Chemical reactivity studies of the organotin(IV) carboxylates diphenyltin(IV) di-4-amino-benzoate (1) and triphenyltin(IV) 4-aminobenzoate (2) were conducted using cyclic voltammetry. Then, their antioxidant activities tested by 2,2-diphenyl-1-picrylshydrazyl (DPPH) method. Cyclic voltammetry was used to determine kinetic constants compounds 1 2 for forward chemical reaction (kf). The constant values rate on voltammogram experiment obtained comparing with from digital simulation...

Abstract This paper reports the potency study of organotin(IV) 3-nitrobenzoate as antimalarial agent. The compounds were synthesized by reacting intermediate products dibutyltin(IV) oxide, diphenyltin(IV) dihydroxide and triphenyltin(IV) hydroxide, with 3-nitrobenzoic acid. activity was performed against Plasmodium falcifarum result IC 50 three tested, i.e. di-3-nitrobenzoate, diphenyltinIV) di-3-nitrobenzoate 8.1 x 10 −3 , 5.2 −2 7.2 µg/mL, respectively, while chloroquine gave 2 µg/mL)....

The derivative of flavonoid compounds, artocarpin (1) and artonin M (2), were isolated from the root wood Artocarpus altilis bark A. kemando, respectively. Both plants originated Lampung, Indonesia. structure two compounds has been carefully determined by physical method spectroscopy techniques UV, IR, NMR. in vivo antimalarial test showed very good Plasmodium activity female mice, with ED50 value 34.88 mg/kg body weight (kgBW), whereas vitro strong IC50 0.3 μg/mL (5.967 x 10-7 M).

Cassava is a source of carbohydrates that grows in tropical areas. The largest cassava producing province Indonesia Lampung, and Central Lampung Regency the main production center Province. Plant responses response to drought vary, such as plants wilting, stomata closing, chlorophyll content decreasing. stress inducer used this research was polyethylene glycol. Drought-sensitive will show reduced growth, while tolerant obtain new genotypes are resistant conditions. aim determine...

Salah masalah utama budidaya jeruk adalah terdapat beberapa daerah kondisi tanahnya kering. Penelitian ini bertujuan untuk mengetahui larutan atonik optimum dan konsentrasi PEG toleran pertumbuhan planlet ( Citrus reticulata Blanco var. crenatifolia ) terhadap cekaman kekeringan menggunakan (PEG) 6000, serta karakter spesifik meliputi...

Abstract This paper deals with short review about the application of organotin(IV) compounds. The discovery bacterial resistance to antibiotics drew attention chemists discover new types chemical compounds that have antibacterial activity overcome resistance. Increased antibiotic is a consequence evolution and adaptation microbes, caused by excessive anthropogenic consumption. cases will be bigger problem if not treated antibiotics. medicinal chemicals may contribute advancement treatment,...

Manganese silicate is one of manganese mineral which barely exploited for processing and extraction compared to other minerals such as pyrolusite, psilomelane rhodochrosite. ore could not directly be leached out in the hydrometallurgical process due strong bonding between silicon manganese. At same time, traditional high-temperature treatment (pyrometallurgy) was unfavorable terms high consumption energy additives (flux). Therefore, this research fusion pre-treatment would proposed break...

Abstract The moon orchid [ Phalaenopsis amabilis (L.) Bl.] is a popular in the community, native from Indonesia, and included list of endangered species. pathogenic fungus that often attacks leaves Fusarium oxysporum , which causes fusarium wilt. Control diseases do not cause negative impacts can be done using superior cultivars resistant to F. infection, through vitro selection medium with addition fusaric acid. Fusaric acid metabolite produced by several fungal species genus at non-toxic...
