Analisis Kadar Asam Lemak Omega-3 dan Mutu Simplisia Herba Krokot (Portulaca oleraceae L.)

Abstract

Omega-3 fatty acids are plural unsaturated fatty acids wich have double bond located in the third hydrocarbon chain of the methyl group, which consists of α-Linoleic (octadekarrienoate), EPA (eikosampentaenoate) and DHA (dekosahesaenoeat), wich many have found in purslane plant. This study aims to determine the levels of Omega-3 fatty acids and the quality of simplicia herbs Purslane (Portulaca oleraceae L.) from Southeast Sulawesi as a raw material for herbal preparations, based on two different drying methods, wich are direct sunlight drying and aerating methods. The parameters seen from the analysis of simplicia quality of purslane herb Portulaca oleraceae L.) include specific and non-specific parameters, which include organoleptic, water content, total ash content, acid insoluble ash content, water soluble extract content, ethanol soluble extract content and fatty acid content omega-3. The quality of simplicia to be used as raw material must meet the quality requirements listed in the official monograph of the Ministry of Health such as Materia Medika Indonesia. Based on the results of the analysis of the quality of simplicia and the levels of omega-3 fatty acids that meet the requirements stated in the simplicia monograph. Is the direct sunlight drying method wich many water content of 8%, 7.6% of total ash, 1% of acid insoluble ash, 8.5% of drying loss, 15% of water soluble extract, and 13% of ethanol soluble extract. The CG test result of omega-3 fatty acids through using the drying method under the sun was 24.28% relative. While the aerated drying method result was 14.31% relative.
