Abstract
The aim of the present study was to determine if Cuscuta pedicellata extract has an effect on body weight and serum lipid profile in the HFD-fed rats’ animal model. The ethanol extract of C. pedicellata exhibited a significant reduction in body weight and serum lipid profile in this model. The n-hexane/EtOAc (1:1), EtOAc and MeOH/EtOAc (1:1) fractions were also active, while the MeOH fraction showed no beneficial effect. Bioactivity-guided fractionation leads to the isolation of ten pure compounds: naringenin (1), kaempferol (2), aromadenderin (3), quercitin (4), 3,5,7,3′,5′-pentahydroxy flavanone (5), naringenin -7-O-β-d-glucoside (6), aromadenderin -7-O-β-d-glucoside (7), Taxifolin -7-O-β-d-glucoside (8), kaempferol -3-O-β-d-glucoside (astragalin), (9) and quercitin -3-O-β-d-glucoside (isoquercitrin) (10). This is the first report of compounds 1, 3, 5, 6, 7, and 8 in Cuscuta pedicellata. Compound 1 > compound 8 > compound 3 > compound 7 > compound 4 > compound 2 are responsible for the potency of the ethanol extract, while compound 6 was only effective in reducing the total cholesterol serum levels but not effective in reducing the level of triglycerides or the body weight. Our data confirmed the anti-obesity effect of C. pedicellata reported by the Egyptian population and identified the compounds responsible for this activity.
