Abstract

Ginger (Zingiberis Officinale) is a type of plant that belongs to the rhizome plant type, ginger is commonly used by the community as an ingredient for herbal drinks, based on this, it is necessary to have a simple extraction that can be used by the wider community to obtain a purer ginger extract, in this study it was conducted that the extraction or separation process of 100 grams of ginger simplicia through the maceration process yielded 27.9 grams, then a purity test was carried out using the principle of TLC (Thin Layer Chromatography) test with eluent or the mobile phase used was methanol, ethyl acetate and N hexane with a ratio of 7:7:6, and an Rf result of 0.18 was obtained based on the distance of the extraction spot divided by the distance traveled by the eluent, and the results of the TLC plate were visible using 254 nm and 366 nm UV light. Based on these results, it can be concluded that the extraction carried out on ginger simplicia was successful.

Abstract

Vitamins are a class of organic compounds that have a very important role for growth, maintenance of health, and other bodily functions so that the metabolism runs normally. There are lots of vitamins both of natural origin and those synthesized in the laboratory. One of them is vitamin C, this study aims to determine the levels of vitamin C (ascorbic acid) in samples of citrus fruit, lime and vitacimin by iodimetric titration. Redox titrations are titrations that involve oxidation and reduction processes. These two processes always occur simultaneously. In redox titrations usually use potentiometric to detect the end point. To determine vitamin C levels, the redox titration method used is direct titration using iodine. Iodine will oxidize compounds that have a smaller reduction potential than iodine. Based on the experiments conducted on the vitamin C test, it can be concluded that the determination of vitamin C levels by iodometric titration can be carried out on the principle of oxidation reduction. Vitamin C levels were obtained by iodometric titration method first which was carried out by diluting oranges, limes and vitamin C by 0.0006%, 0.0006287%, 0.000787%. In the second method without dilution, the concentration of vitamin C in oranges and limes is 0.03165%, 0.0 9%.
