Extraction, Pursalene, Total Phenolics Content, Infusion, DecoctionAbstract
Pursalene (Portulaca oleracea Linn.) is rich in phenolic contents, which can be used to treat metabolic syndrome. An extraction method is needed to obtain efficacious phenolic contents from the purslane plant. However, no literature examines the effect of selecting the infusion vs decoction extraction method on the levels of total phenolic contents from purslane plants. This research aims to determine the effect of application the infusion vs decoction extraction method on the levels of total phenolic contents obtained from purslane plants. The infusion and decoction extraction methods were carried out using water as solvent 1:10 w/v (powder/solvent) at 90°C. In the infusion method, extraction is carried out using a tightly closed container for 15 minutes, while in the decoction method extraction is carried out until the volume of the solution is reduced by half. Determination of total levels of phenolic contents was carried out spectrophotometrically using Folin-Ciocalteu reagent at 750 nm. The choice of conventional extraction methods, infusion and decoction has a significant effect. (2-tailed) < 0.05 on the total content of phenolic contents obtained from the Portulaca oleracea Linn. The decoction extraction method was used more effectively to extract phenolic contents from the pursalene plant, producing total phenolic content levels of 377.60 ± 2.44 mgGAE/g dry extract when compared to infused extract, which only produced total phenolic content levels of 121.33 ± 1.16 mgGAE/g dry extract.
