Abstract

Brown macroalgae (BM) which contain fucoxanthin exhibited high antioxidant activity. This study was performed to examine antioxidant, anti-collagenase, anti-elastase, anti-tyrosinase activities, and effect on cell viability of Human Dermal Fibroblast adult (HDFa) of BM, Turbinaria decurrens Bory. T. decurrens dried powder were macerated by ethanol to obtain extract (ETD) and was fractination by column chromatography to obtain fraction (FTD). Fucoxanthin content was determined using HPLC. The antioxidant activities, anti-collagenase, anti-elastase, and tyrosinase inhibitory assay were performed. The effect of ETD and fucoxanthin standard on cell viability were conducted on HDFa cell-induced by hydrogen peroxide (H2O2). The HPLC analysis showed that ETD and FTD contain fucoxanthin of 284.9±3.3µg/g and of 653.4±30.6µg/g dry-weight, respectively. The antioxidant assay showed that ETD and FTD produced high antioxidant activity by ferric reducing antioxidant power (FRAP) and b-carotene bleaching (BCB) methods that were comparable to fucoxanthin. ETD exhibited significantly higher tyrosinase inhibitory than kojic acid (p<0.01), while FTD had a comparable effect to kojic acid. The result also revealed that ETD and FTD produced anti-elastase and anti-collagenase (matrix metalloproteinase-1 (MMP-1). Fucoxanthin and ETD were able to maintain cell viability on HDFa cell-induced H2O2. This study suggests that T. decurrens may be effective to prevent skin aging and wrinkle formation, possibly through the antioxidant activity and maintain cell viability of fibroblast.

Abstract

Plastic can cause some problems, especially in parenteral product. Main disadvantage of using plastic container is  plastic has capability to absorp many compounds which in solution. Furthermore, it can cause decreasing of drug concentration which having an effect on efficacious of drug. This research aims to know the influence of autoclave sterilitation process and Low Density Polyethilene (LDPE) plastic container to decreasing of D-Manitol concentration in parenteral dosage form. Beside that, the other purpose is searching sterilization temperature which have high safety and effectivity. The research includes making D-Manitol 20% solution and then determination of its concentration. After that, the D-Manitol solution is divided into two groups. One group is as control solution (without plastic LDPE) and another group is as sample (with plastic LDPE). Then, both of solutions are strerilized at three temperature programs (100°C, 102°C, 105°C). The results show that sterilization by autoclave and plastic presence in D-Manitol solution can cause concentration D-Manitol decreasing. The decreasing of D-Manitol concentration is not more than 5%, so that it is accepted in accordance with rule of Indonesian Pharmacope 4th edition. The best condition of sterilization is 100°C temperature during 45 minutes. ABSTRAK Plastik dapat menimbulkan masalah, terutama dalam sediaan parenteral. Kerugian utama penggunaan pengemas plastik adalah plastik mempunyai kemampuan untuk menyerap banyak komponen dalam larutan sediaan. Selanjutnya dapat mengakibatkan berkurangnya kadar obat yang berpengaruh pada kemanjuran obat tersebut. Penelitian ini bertujuan untuk mengetahui pengaruh suhu sterilisasi autoklaf dan bahan pengemas plastik Low Density Polyethilene (LDPE) terhadap penurunan kadar larutan D-Manitol sediaan parenteral (Injeksi D-Manitol). Di samping itu bertujuan untuk mencari suhu sterilisasi yang paling aman dan efektif. Penelitian meliputi pembuatan larutan D-Manitol 20% kemudian dilakukan penetapan kadar awal. Larutan dibagi menjadi dua kelompok untuk kontrol (tanpa plastik LDPE) dan sampel (dengan penambahan plastik LDPE), kemudian disterilisasi pada tiga paket suhu (100°C, 102°C, 105°C). Hasil penelitian yang diperoleh menunjukkan bahwa perlakuan sterilisasi dengan autoklaf menggunakan variasi suhu pada larutan D-manitol tanpa penambahan plastik dan dengan penambahan plastik menyebabkan terjadinya penurunan kadar D-Manitol. Besarnya penurunan kadar D-Manitol tidak lebih dari 5%, sehingga masih dapat diterima berdasarkan Farmakope Indonesia IV. Suhu sterilisasi 100°C selama 45 menit merupakan kondisi sterilisasi yang paling efektif dan aman.

Abstract

Gas chromatography with electron capture detector (GC-ECD) has been validated for simultaneous determination of selected organochlorine pesticides namely heptachlor, endosulfan, dieldrin, dan p,p’-dichlorodiphenyltrichloroethane (p,p’-DDT) using aldrin as standard internal. Some parameters for analytical method validation were evaluated, i.e. linearity, precision, sensitivity expressed with limit of detection and limit of quantification, and recovery. GC-ECD was linear for determination of these pesticides with r values ≥ 0.99. The values of LOD obtained were 2.50, 2.97, 1.61, and 2.54 ng/mL for heptachlor, endosulphan, dieldrin, and p,p’-DDT, respectively. Furthermore, the relative standard deviation (RSD) values obtained for the assessment of analytical precision were lower than those required by Horwitz. Finally, the used GC-ECD method was accurate for determination of these organochlorine psticides in fortified rice samples which were indicated by the acceptable recovery percentages.

Abstract

As a pollutant, the presence of Poly Aromatic Hydrocarbons (PAH) in the environment must be always monitored, because of their ability to spread widely through the food chain and also their carsinogenic properties. The solubility of PAH in water is very low, therefore it is difficult to analyze their presence in water environment by using water as a sample. By utilizing the phenomenon of the accumulation of PAH in biolipids, the analysis method has been developed using bioindicators. In this research, the concentration of four kinds of PAH (pyrene, benzo(a)anthracene, benzo(k)fluoranthene and perylene) in several samples (water, plankton, algae and fish) that collected from the south sea Jogjakarta has been determined. The bioaccumulation factor (BAF) of PAH in each sample has been calculated and the results were from 4498 to 432754; 2552 to 49265; 14156 to 730991, respectively for plankton, algae and fish.  Based on the BAF values, plankton can be used as a bioindicator for short term PAH monitoring, while the Upeneus moluccensis fish primarily gills organ can be used as a bioindicator for medium term (months) PAH monitoring.Key words :  poly aromatic hydrocarbons, bioaccumulation factor, bioindicator, Upeneus moluccensis

Abstract

The polycyclic aromatic hydrocarbons (PAHs) are a class of organic compounds, composed two or more fused aromatic (benzene) rings, occurred in the environment due to incomplete combustion of organic matters such as forest fires, volcanic eruption, burning of fossil fuels and incorrect process of meat cooking (grilling, smoking, roasting). Healt concerns are focussed on the metabolite transformation of PAHs, which may have mutagenic, carcinogenic and terratogenic activity. Due to their hydophobicity, it is probable the compounds enter human food chain and accumulated in human lipid tissues. Therefore, environment pollution by PAHs must be considered. PAHs gain entry to human body through several routes including respiration, absorpsion through skin surface ang through food consumption that have been polluted with PAHs. In this study concentrations of PAHs (pyrene, perilene, benzo(a)anthracene, benzo(k)fluorantrene and benzo(a)pyrene) in traditional smoked meat, liquid smoked meat and roasted meat are determined. Determination of PAHs used gas chromatograph with OV 17 2% as a stationary phase, nitrogen as carrier gas and flame ionization detector. The results showed that PAHs concentrations in traditional smoked meat were higher than liquid smoked meat (41.19 ppb and 1.03 – 9.26 ppb). In the roasted meat, lipid concentration and roasting time influence PAHs concentration level.Keywords : polycyclic aromatic hydrocarbon, smoked meat, liquid smoke

Abstract

In the last decade, Indonesia intensifies the efforts to reduce pharmaceutical imports. One of the initiatives is establishing a paracetamol production facility to start operating in 2024. Kinetics study is needed as a basis to design the paracetamol reactor. This study investigated the optimal temperature, reactant mole ratio, and agitation speed in the reactor for paracetamol production. In this study, aqueous solution of para-aminophenol was reacted with acetic anhydride. The mole ratio of para-aminophenol to acetic anhydride was varied to 1:1, 1:1.2, 1:1.5, and 1:2 while the temperature was varied to 80 °C, 90 °C, and 110 °C. However, due to uncontrolled heat of the reaction and limitation of the mixture’s boiling point, the actual reaction temperatures were 86 °C, 90 °C, and 108 °C. In addition, the agitation speed of 250 RPM and 350 RPM were also studied. Thin layer chromatography (TLC) and densitometry were used to determine the concentration of paracetamol in the reacting mixture. The optimum temperature, reactant mole ratio, and agitation speed in this study were 108 °C, 1:1.5, and 350 RPM, respectively. In addition, a reaction performed under those operating parameters gave the reaction rate constant of 1.95 L mol-1 min-1.Keywords: acetic anhydride; kinetics; para-aminophenol; paracetamol; pharmaceutical industry A B S T R A KDalam sepuluh tahun terakhir ini, Indonesia bertekad mengurangi impor bahan baku farmasi. Salah satu upaya yang dilakukan adalah membangun fasilitas produksi parasetamol yang akan mulai beroperasi pada tahun 2024. Studi kinetika diperlukan sebagai dasar perancangan reaktor parasetamol. Oleh karena itu, penelitian ini mengkaji kondisi operasi optimal pada reaksi produksi parasetamol yang akan dibutuhkan sebagai dasar perancangan pabrik. Pada percobaan ini, para-aminofenol direaksikan dengan anhidrida asetat dengan media air. Rasio mol para-aminofenol terhadap asetat anhidrida divariasikan 1:1 1:1,2, 1:1,5, dan 1:2 sedangkan temperatur divariasikan 80 °C, 90 °C, dan 110 °C. Akan tetapi, karena panas reaksi yang tidak dikontrol dan batasan berupa titik didih dari campuran reaksi, temperatur aktual reaksi menjadi 86 °C, 90 °C, dan 108 °C. Selain itu, kecepatan putaran pengadukan juga divariasikan pada angka 250 RPM dan 350 RPM. Kromatografi lapis tipis (KLT) dan densitometri digunakan untuk menentukan konsentrasi parasetamol dalam campuran reaksi. Temperatur, rasio mol reaktan, dan kecepatan putaran pengadukan yang optimum pada penelitian ini masing-masing adalah 110 °C, 1:1,5, dan 350 RPM. Selain itu, reaksi yang dilakukan dengan kondisi operasi tersebut menghasilkan konstanta laju reaksi 1,95 L mol-1 menit-1.Kata kunci: anhidrida asetat, industri farmasi, kinetika, para-aminofenol, parasetamol

Abstract

Propagermanium, a synthetic organic compound of germanium is known as β- or biscarboxyethylgermaniumsesquioxide or Ge-132. It is found in some plants such as shelf fungus,ginseng, garlic, and Aloe vera. Ge-132 plays an important role for the pharmacological effectsof the plants. The solubility of propagermanium at a certain pH is not exactly known yet. Untilnow, the analytical methods for the analysis of Ge-132 so far have the shortcoming and thepropagermanium as germanium metal in the sample, so that improvement for propagermaniumanalysis was necessary to be conducted, primarily to be used for solubility assay. This studyaims to determine the effects of pH on the propagermanium solubility using HPLC method foranalysis. The results showed that validation parameters for analysis by using HPLC method e.iaccuracy, precision, and linearity, have met to the quantitative analysis requirements. Increasingthe pH causes increasing the solubility of propagermanium in the pH range of 3.0-3.6. Thesolubility result was 9.8514; 10.4204; 12.5446 mg/mL on pH 3.0; 3.3; 3.6.
