Protective Effect of Pulp Oil Extracted from Canarium odontophyllum Miq. Fruit on Blood Lipids, Lipid Peroxidation, and Antioxidant Status in Healthy Rabbits

Abstract EN

The aim of this paper was to compare the effects of pulp and kernel oils of Canarium odontophyllum Miq.

(CO) on lipid profile, lipid peroxidation, and oxidative stress of healthy rabbits.

The oils are rich in SFAs and MUFAs (mainly palmitic and oleic acids).

The pulp oil is rich in polyphenols.

Male New Zealand white (NZW) rabbits were fed for 4 weeks on a normal diet containing pulp (NP) or kernel oil (NK) of CO while corn oil was used as control (NC).

Total cholesterol (TC), HDL-C, LDL-c and triglycerides (TG) levels were measured in this paper.

Antioxidant enzymes (superoxide dismutase and glutathione peroxidise), thiobarbiturate reactive substances (TBARSs), and plasma total antioxidant status (TAS) were also evaluated.

Supplementation of CO pulp oil resulted in favorable changes in blood lipid and lipid peroxidation (increased HDL-C, reduced LDL-C, TG, TBARS levels) with enhancement of SOD, GPx, and plasma TAS levels.

Meanwhile, supplementation of kernel oil caused lowering of plasma TC and LDL-C as well as enhancement of SOD and TAS levels.

These changes showed that oils of CO could be beneficial in improving lipid profile and antioxidant status as when using part of normal diet.

The oils can be used as alternative to present vegetable oil.
