Abstract

The purpose of this research is to integrate to provide design recommendations for the implementation of good natural product chemistry (NPC) laboratory activity. This study was used systematic review which consists of data presentation, data reduction, and drawing conclusions. The data sources come from several articles. The data are: (1) data on natural product chemistry (NPC) laboratory activity methods, (2) data on the validity of the natural product chemistry (NPC) laboratory activity module, (3) data on the effectiveness of the natural product chemistry (NPC) laboratory activity module method data. Module validity was analyzed using the aiken index. The results of the analysis show that the implementation of the natural materials practicum will be carried out if it meets several requirements, namely (1) practicum design (2) practicum module. The validity results show that the natural materials chemistry practicum module is very feasible and practical to use.

Abstract

The curcumin compounds in Temulawak Rhizome have been isolated and identified.. This study aims to identify curcumin compounds in temulawak rhizome by modifying methods that pay attention to the efficiency of funds and the use of materials. In general, the method of isolation and identification is carried out. The methods used are (1) Extraction, (2) Thin Layer Chromatography, (3) Column Chromatography and (4) Infrared (IR) Testing. Based on comparing the sample's Retention Factor (RF) value with the standard curcumin compound, the results were identical, and the positive sample contained a curcumin compound. The results of the Infrared spectrum can be assumed that the sample is a flavanols group, which can be seen from the wavelength range of identical functional groups in curcumin compounds.
