Analysis of Contaminant and Nutritional Content of Red Galangal (Alpinia purpurata K. Schaum) Simplicia

Abstract

This study has been conducted analysis of contaminant and nutritional content of red galangal (Alpinia purpurata K. Schaum) simplicia. Simplicias as one of post-harvest processed form. Simplicia is a material to produce herbs medicine. So that, simplicia quality must be considered. The quality of simplicias depends on two parameters that are contaminant and nutritional content. Contaminants can reduce product quality, so it must be controlled. As well as contaminant, nutritional content also must control, because it is affected quality of simplicia product. Nutritional content that must be controlled are essential oil, monoterpene on essential oil, oleoresin, saponin, tannin, and flavonoid. Simplicia is produced by, washing, slicing and drying methods. Whereas contaminants contained in simplicia are lead, copper, arsenic, total plate number, E. Coly, mold, and aflatoxin. From this study, produced red galangal simplicia with nutritional content, 1.98% essential oil, 37.92% monoterpene on essential oil, 1.34% oleoresin, 0.74% saponin, 0.21% tannin, and 0.12% flavonoid. While, contamination on simplicia product includes 1.13 mg/Kg lead, 1.21 mg/Kg copper, 0.05 mg/Kg arsenic, 1.93x104 colony/g total plate number, < 10 apna/g E. Coli, <10 colony/g mold, and 2.76 mg/Kg aflatoxin. From the result of this study, that are contaminants and nutritional content, the simplicia product has conformed to the standard of drug quality according to SNI.
