Abstract

The objectives of the study are to determine the best condition for Eucheuma cottonii, obtained from Bantaeng regency, to produce κ-Carrageenan and to determine the characteristics of the carrageenan. Concentration of NaOH and KCl that are used to extract carrageenan, extraction time, and precipitation time are some variables that are measured for carrageenan extraction. After the best extraction condition is found, then the next step is characterization of the produced carrageenan. The best combination found to extract the highest amount of carrageenan are NaOH 4%, extraction time of 1 hour, KCl 6%, and precipitation time of 1 hour as well. For the characterization of ash, fiber, sulfate content, and viscosity are 2.24%; 0.65%; 0.35%; and 5 cP respectively.

Abstract

Meistera aculeata (Roxb). Skornick. & M.F. Newman belongs to the ginger family (Zingiberaceae) and locally known as ‘Susube’ by natives of Konawe district of Southeast Sulawesi. M. aculeata is an endemic plant and its fruit has been consumed by the locals. Until today, study on chemistry and biological activity aspects of M. aculeata has yet investigated. Hence, this research aimed to identify phytochemical contents and acute toxicity of M. aculeata fruits extracted using ethanol as the solvent. Phytochemical screening showed the accumulation of alkaloids, tannins, flavonoids, terpenoids, and saponins in the ethanol extract of M. aculeata fruits. Meanwhile, the Brine Shrimp Lethality Test (BSLT) revealed that ethanol extract of M. aculeata fruits has a weak acute toxicity (LC50 683,9 ppm) when compared with potassium dichromate as the positive control of the assay (LC50 8,3 ppm). The study concluded that M. aculeata fruits could be used in the development of drugs from natural sources.

Abstract

Liquid soap is a cleaning agent made from a chemical reaction between potassium hydroxide and fatty acids from vegetable oils and animal fats. This study aims to determine the quality and formulation used in making antiseptic liquid soap from aloe vera with the variation of Sodium Lauryl Sulfate (SLS). Previous research on making liquid soap from aloe vera produced soap with free alkaline levels and a high pH and still lacking foam. In this study, liquid soap was made by adding variation of SLS (Sodium Lauryl Sulfate), as a foam booster and citric acid as a substance that can control the pH of the soap. The resulting liquid soap product was analyzed for pH value, foam stability, free alkali content/FFA, viscosity, density, ALT and bacterial test. The results showed that each soap formula produced match with the requirements of SNI 2588-2017 and the best formulation is the F2.
Synthesis of 3-(3,4-diacetoxyphenyl)acrylic acid and 4-(oxo-3-(piperidin-1-yl)pro-1-en-1-yl)-1,2-phenylendiacetate from 3-(3,4-dihydroxyphenyl)acrylic acid and their toxicity test by Brine Shrimp Lethality Test method Musrifah Tahar; Nunuk Hariani Soekamto

Abstract

Derivatization 3-(3,4-dihydroxyphenyl)acrylic acid to 3-(3,4-diacetoxyphenyl)acrylic acid (1) and 4-(oxo-3-(piperidin-1-yl)pro-1-en-1-yl)-1,2-phenylendiacetate (3) and its toxicity test has been successfully carried out. Derivatization was carried out through acetylation, chlorination, and amidation reactions. The acetylation reaction was carried out using acetic anhydride in pyridine solvent at room temperature for 4 hours to produce compound 1 as a white amorphous solid with m.p. 181-183oC and yield of 85.68%. The chlorination reaction was carried out using thionyl chloride in toluene solvent at the reflux temperature of 79°C for 4 hours and continued with in situ amidation using piperidine in dichloromethane solvent at room temperature to produce compound 3 as a white crystal with m.p. 139-141oC and yield of 39.45%. The toxicity test of the two compounds against Artemia salina Leach shrimp larvae using probit analysis showed that compounds 1 and 3 were toxic with LC50 values ​​of 8.919 μg/mL and 84.511 μg/mL, respectively. This data shows that the acetylation of 3-(3,4-dihydroxyphenyl)acrylic acid compound (LC50 = 46.50 μg/mL) increases the toxicity to larvae of Artemia salina Leach shrimp. Keywords: 3-(3,4-dihydroxyphenyl)acrylic acid, 3-(3,4-diacetoxyphenyl)acrylic acid, 4-(oxo-3-(piperidin-1-yl)pro-1-en-1-yl)-1,2-phenylendiacetate, Artemia salina Leach.

Abstract

Mycobacterium tuberculosis is a bacterium that causes tuberculosis infection disease. The aim of this study was to produce complex compounds that have the ability to damage the cell wall of Mycobacterium tuberculosis. Gd(III)Heptylmethyldithiocarbamate 2,9-dimethyl phenanthroline complex was synthesised and characterised by reacting N-heptylmethylamine, carbondisulphide, 2,9-dimethyl phenanthroline and lanthanide group metal ion (Gadolinium) using in situ method. Characterisation was carried out using electrothermal melting point, conductometer, UV-Vis spectrophotometer, and FT-IR spectrophotometer. The resulting Gd(III)Heptylmethyldithiocarbamate 2,9-dimethyl phenanthroline complex was white in colour as much as 7.01%, conductivity 20 Ω-1 and melting point 208-210o C. Testing of complex compounds gave effective results as antibacterial Mycobacterium tuberculosis.
