PENGARUH VCO MENGANDUNG EKSTRAK WORTEL TERHADAP PEROKSIDASI LIPID PLASMA Lidya Irma Momuat1), Meiske S.

Kata kunci: malondialdehida, minyak kelapa, wortel EFFECT OF VIRGIN COCONUT OIL (VCO) CONTAINING CARROT EXTRACT ON PLASMA LIPID PEROXIDATION ABSTRACT The aim of this study was measure the level of lipid oxidation in the blood plasma of rats fed VCO containing carrot extracts. Male Wistar rats in this study were divided into four groups: (i) control, (II) 10% VCO without the carrot extract, (III) 10% VCO containing carrot extracts, and (IV) 10% corn oil. After 4 weeks of treatment, blood from each rat was taken by syringe.  Plasma is separated from whole blood by centrifugation for analysis of plasma oxidation levels by measuring the malondialdehyde (MDA) concentration using tiobarbituric acid test. The results showed that the highest concentration of MDA was found in rats fed corn oil (11.253 m M), followed by the control group (10.167 m M), then rats fed VCO containing carrot extract (8.656 m M) and VCO (8.269 m M). This study concluded that the level of plasma lipid oxidation in rats fed VCO containing carrot extracts is relatively similar to rats fed VCO without the carrot extract, but it is lower than the control and corn oil groups.
