title: Protective Effects of Tamarillo (Cyphomandra betacea) Extract against High Fat Diet Induced Obesity in Sprague-Dawley Rats.
abstract: This study aims to investigate the protective effect of Cyphomandra betacea in adult male Sprague-Dawley rats fed with high fat diet. Rats were fed on either normal chow or high fat diet for 10 weeks for obesity induction phase and subsequently received C. betacea extract at low dose (150 mg kg(-1)), medium dose (200 mg kg(-1)), or high dose (300 mg kg(-1)) or placebo via oral gavages for another 7 weeks for treatment phase. Treatment of obese rats with C. betacea extracts led to a significant decrease in total cholesterol and significant increase in HDL-C (p < 0.05). Also there was a trend of positive reduction in blood glucose, triglyceride, and LDL-C with positive reduction of body weight detected in medium and high dosage of C. betacea extract. Interestingly, C. betacea treated rats showed positive improvement of superoxide dismutase (SOD) activity and glutathione peroxidase (GPx) activity along with a significant increase of total antioxidant status (TAS) (p < 0.05). Further, rats treated with C. betacea show significantly lower in TNF-α and IL-6 activities (p < 0.05). This study demonstrates the potential use of Cyphomandra betacea extract for weight maintenance and complimentary therapy to suppress some obesity complication signs.
