In this study, we analyzed the biochemical factors in lotus (Nelumbo nucifera) leaf, stem, and yeonjabang and their effects on serum factor levels in mice fed a high-fat (HF) diet. The loutus leaf showed 9.47±0.30% moisture content, 8.25±0.39% ash, 21.45±1.25% crude protein, and 2.21±0.13% crude fat content; the lotus stem showed 11.84±0.43% moisture, 10.21±0.64% ash, 17.55±0.92% crude protein, and 4.16±0.23% crude fat content; and the lotus yeonjabang showed 11.86±0.50% moisture, 6.81±0.51% ash, 18.71±1.02% crude protein, and 3.95±0.15% crude fat. Blood triglyceride levels were higher in the HF group (146.43±38.81 mg/dL), and lower in the HF+yeonjabang groups (98.00±17.18 mg/dL). In particular, blood triglyceride levels were significantly lower in the groups that had 10% dry yeonjabang powder added to the high-fat diet. The inclusion of excessive high-fat diet increased concentrations of serum insulin and leptin. Serum leptin concentrations were highest in the HF group mice (3.00±1.35 ng/dL), whereas they were significantly lower in the HF+yeonjabang groups by 1.34±0.52 ng/dL (p<0.05). Thus, addition of dry yeonjabang powder to the high-fat diet was more effective in regulating the levels of serum triglycerides and leptin in mice. Additional studies would help in the development of yeonjabang as a functional food.
