Modificated Extraction and Purity Test of Arenga Pinnata Gum

Abstract

Objective: The purpose of this study is modificated extraction method to obtain gum from Arenga pinnata Merr. and their purity test.Methods: Gum has been extracted from palm seed using distilled water by centrifugation and warming. Characterization of gum was done by scanning electron microscopy-energy dispersivse X-ray and spectrophotometer infrared. Gum refluxed with HCl 2 N for 14 h would be the monomer. Galactose and mannose were used as standard. Purity test was done by the thin-layer chromatography (TLC) and Luff Schoorl method.Results: The study results obtained that the modification methods (4.8%) and centrifugation (4.6%). Identification of functional groups with the spectrophotometer infrared provided the same spectrum forms between the two methods. Purity test by TLC with the best eluen butanol: ethanol:water 2:2:2. Luff Schoorl’s method gives results of 87.46%, whereas the raw comparison galactose-mannose standard 96.69%.Conclusions: The modification method gives more results with the same purity rate as the centrifugation method.

Synthesis, Characterization and Cytotoxicity of Certain Peg400 Based Biodegradable Aliphatic Copolyesters

“…The maximum cancerous cell death occurred in sebacate when compared with succinate. Therefore from these results we conclude that PEDDSE is antiproliferative than PEDDSU 34,35 .…”

Phosphorus Analysis of Phosphorylated Durian Seed Gum by Wet and Dry Digestion

“…This reflux allows perfect heating without worrying about the loss of the analyzed element. The degree of crosslinking on rice starch can be analyzed by dry digestion method at 550°C 7,8 , but this does not apply to gum. Gum belongs to the oligosaccharide consisting of 2-6 monosaccharides, while the starch is classified as polysaccharides composed of more than 6 monosaccharides.…”

“…Gum and starch have differences where gums include water-soluble polysaccharides while starches do not 5 . Durian seed gum is obtained by extracting the durian seed with water and then salting out with the addition of ethanol to obtain dry gum 6,7 . Research of phosphorylated durian seed gum with STMP has not been done so it is considered necessary to investigate the analysis of phosphorus levels and cross-link phosphate levels after cross-linked with STMP.…”

"Synthesis, Characterization and Comparison of Biodegradable Aliphatic Copolyesters: Poly Ethylene Glycol Octanediol Sebacate and Polyethylene Glycol Dodecanediol Adipate"

“…While comparing the sebacate and adipate polymer with the standard drug tetracyclin, the adipate polymer showed more activity towards the gram-negative bacteria (E. coli and P. aeruginosa). Similarly, in the comparison with gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus), the rate of inhibition was found to be higher for adipate polymer than sebacte polymer 40,41 . From the results of Antifungal data against Candida Albicans, the sebacate polymer alone was active at higher concentrations and adipate polymers showed nil activity.…”
