Abstract Bitter melon (Momordica charantia L.) has been shown to have various health-promoting activities, including antidiabetic and hypoglycaemic effects. Improvement in insulin sensitivity and increase in glucose utilisation in peripheral tissues have been reported, but the effect on insulin secretion from pancreatic β-cells remains unclear. In this study, we investigated the effect of bitter melon fruit on insulin secretion from β-cells and the underlying mechanism. The green fruit of bitter melon was freeze-dried and extracted with methanol. The bitter melon fruit extract (BMFE) was fractionated using ethyl acetate (fraction A), n-butanol (fraction B) and water (fraction C). Insulin secretory capacity from INS-1 rat insulinoma cell line and rat pancreatic islets, as well as glucose tolerance in rats by oral glucose tolerance test (OGTT), was measured using BMFE and fractions. ATP production in β-cells was also examined. BMFE augmented insulin secretion from INS-1 cells in a dose-dependent manner. The significant augmentation of insulin secretion was independent of the glucose dose. Fraction A (i.e. hydrophobic fraction), but not fractions B and C, augmented insulin secretion significantly at the same level as that by BMFE. This finding was also observed in pancreatic islets. In OGTT, BMFE and fraction A decreased blood glucose levels and increased serum insulin levels after glucose loading. The decrease in blood glucose levels was also observed in streptozotocin-induced diabetic rats. In addition, BMFE and fraction A increased the ATP content in β-cells. We concluded that hydrophobic components of BMFE increase ATP production and augment insulin secretion from β-cells, consequently decreasing blood glucose levels.

Abstract: Salmonella typhi is a gram-negative bacteria species that causes typhoid fever. Salmonella typhi is sensitive to antibiotics such as amoxicillin, chloramphenicol, ciprofloxacin, and cotrimoxazole. However, there has been some increase in antibiotic resistance, so there is a need for new antibacterials that do not have a resistance effect to treat infection. Bligo fruit (Benincasa hispida (Thunb) Cogn) and bitter melon (Momordica charantia L.) contain saponins, tannins, flavonoids, alkaloids, and triterpenoids which have antibacterial power. The purpose of this study was to compare the effectiveness of the bligo fruit extract (Benincasa hispida (Thunb) Cogn) and bitter melon extract (Momordica charantia L.) on the minimum inhibition of Salmonella typhi bacteria. The method used is narrative literature review. The results of the journal study showed that the extract of bitter melon (Momordica charantia L.) was more effective in inhibiting Salmonella typhi bacteria than the extract of bligo (Benincasa hispida (Thunb) Cogn) with a minimum inhibitory power at a concentration of 20%, namely 8.5 mm. Keywords: Bligo Fruit (Benincasa hispida (Thunb) Cogn), Bitter Melon (Momordica charantia L.), Salmonella typhi.
