Diabetes mellitus (DM) is associated with protein catabolism due to a decrease in insulin secretion.The profile of plasma protein is a strong predictor of protein metabolism disorder.Glycine max (G. max) and Zingiber officinale (Z. officinalle) are functional food used to cure diseases empirically.However, the potency of herbs to inhibit protein metabolism disorder in DM has not been reported completely.The study aims to examine the effect of G.max and Z. officinale on plasma albumin level, globulin, and total protein of diabetic rats.Diabetic rats (spraque dawley) were induced by High Fructose High Fat Diet (HFHFD) and single-dose streptozotocin 25 mg/kg bw i.p.The 5000 mg/kg bw G.max, 500 mg/kg bw Z. officinale, and its combination was given orally to the rat 4 wk.The level of plasma albumin, globulin, and total plasma protein was measured using a spectrophotometer.The data was analyzed using ANOVA test continued with the LSD test (p<0.05).The oral administration of G.max, Z. officinale, and their combination decreases plasma albumin level, globulin, and total plasma protein compared to the diabetic group (p<0.05).In the diabetic group, plasma albumin level, globulin, and total plasma protein increases compared to the normal group (p<0.05).
