Abstract
BACKGROUNDS Recent experiments suggest that Citrus bergamia extracts could benefit people with dyslipidemia and obesity but this needs to be further validated. METHODS A total of 98 people age-matched older adults (65 years) with elevated blood lipids were enrolled to receive 12-week supplementation of a Citrus bergamia extracts-based formulation (CitriCholess)(n = 48) and placebo (n = 50). RESULTS No group differences were found in baseline bodyweight, body mass index (BMI), blood cholesterol (TC), triglycerides (TG), low density lipoprotein cholesterol (LDL-C) and glucose levels. CitriCholess supplementation resulted in lower levels than placebo in TG (1.83 ± 0.92 vs. 1.95 ± 1.34 mmol/L, P = 0.612), TC (5.14 ± 0.98 vs. 5.44 ± 0.77 mmol/L, P = 0.097), and LDL-C (3.13 ± 0.74 vs. 3.43 ± 0.62 mmol/L, P = 0.032). Compared to placebo, CitriCholess also resulted in greater reductions in body weight (-0.604 ± 0.939 vs. 0.06 ± 0.74 kg, P < 0.01), waist circumferences (-0.60 ± 1.349 cm vs. -0.16 ± 1.503 cm, P < 0.01) and BMI (-0.207 ± 0.357 vs. 0.025 ± 0.274, P < 0.01). Additionally, females had a significantly higher level of HDL-C than males. TC was significantly correlated with LDL-C, and to a less degree, with TG. TG was inversely correlated with HDL-C. Body weight and waist circumference were negatively correlated with HDL-C and positively correlated with glucose. CONCLUSION 12-week supplementation of CitriCholess could benefit lipid metabolism and weight management in old adults with dyslipidemia.

Abstract
Enrichment and separation of genistein and apigenin from extracts of pigeon pea roots were studied using eleven macroporous resins with different physical and chemical properties. ADS-5 resin showed the maximum effectiveness among the tested resins. The solute affinity towards ADS-5 resin at different temperatures was described in terms of Langmuir and Freundlich isotherms, and the equilibrium experimental data were well-fitted to the two isotherms. In order to optimize the operating parameters for separating genistein and apigenin, dynamic adsorption and desorption tests were carried out. After one run treatment with ADS-5 resin, the contents of genistein and apigenin in the product were 9.36-fold and 11.09-fold increased with recovery yields of 89.78% and 93.41%, respectively. The process achieved easy and effective enrichment and separation of genistein and apigenin by using ADS-5 resin, and it is a promising basis for large-scale preparation of genistein and apigenin from pigeon pea or other plants extracts.
