RESUMEN
Objective: To study the effect of flavonoids from seed residues of Hippophae rhamnoides L.( FSH) and Hippophae rhamnoides L. oil(HRO)on serum lipid in female rats with obesity. Methods Female aged rats with obesity were given FSH and HRO by oral administration for 6 w. Serum triglyceride(TG) and cholesterol(TC) were determined every 2 w. The serum free fatty acid (FFA), high-density lipoprotein cholesterol (HDL-C),body weight and Lee’s index were measured after 6 w. Results: Serum TG and FFA level decreased significantly in rats given FSH. At the same time, FSH could inhibit the increase in body weight and Lee’s index. HRO could regulate the lipid metabolism and decrease serum TG level significantly in female aged rats with obesity. Conclusion: Both FSH and HRO can improve lipid metabolism in female aged rats with obesity.
