Bitter melon (Momordica charantia, L) is a fruit that traditionally believe has benefits on health. The objective of this study is to identify bitter melon bioactive and nutritional compounds, and their effect on blood glucose level and lipid profile of streptozotocin induced hyperglycemia rats. Rats were divided into three group, those were normal group; hyperglycemia group without bitter melon fruit feeding; and hyperglycemia group with bitter melon fruit administration. Hyperglycemia condition was achieved by STZ induction. The experiment was conducted for 4 weeks. The results showed that fresh bitter melon fruit contains β-sitosterol 348.16+1.66 ppm, stigmasterol 183.08+0.8 ppm, campesterol 130.79+0.4 ppm, diosgenin 16.42+0.06 ppm, soluble dietary fiber 2.99+0.07%, insoluble dietary fiber 0.55+0.01%, and pectin 1.41+0.05%. At week 4 of experiment, bitter melon fruit fed hyperglycemia group showed a decrease of 56% blood glucose level compared to blood glucose level at week 0. Body weight of this group also increased. The improvement of lipid profile of bitter melon fed group was indicated by decreasing blood total cholesterol of 49%, triglyceride of 35%, LDL cholesterol of 42%, and increasing HDL of 133% compared to initial level at week 0. Bitter melon also increased fecal cholesterol secretion and effectively inhibited cholesterol absorption in hyperglycemia rats. Bitter melon fruit is suggested for hyperglycemia management due to its ability to reduce glucose and improve lipid profile simultaneously.
