A Review of the Pharmacological Effects of Solanum muricatum Fruit (Pepino Melon).

Abstract

Solanaceae, commonly known as nightshade, is a diverse family of flowering plants comprising around 90 genera and an estimated 3000-4000 species. Solanaceae spp. and its various fruits, including pepino (Solanum muricatum), commonly known as pepino melon, are widely recognized by the public for their nutritional value and pharmacological effects. Pepino melon, in particular, is often enjoyed as a fresh dessert or salad due to its juicy flesh. Given its beneficial properties, the potential of pepino melon to be developed as a functional food has been extensively studied. This review aims to provide a comprehensive summary of the reported pharmacological effects of the active compounds found in pepino plant and melon. Among these compounds, polyphenols, notably quercetin, and vitamin C have demonstrated notable antioxidant properties such as scavenging free radicals, effectively protecting against free-radical damage. Moreover, these active ingredients provide pepino with anti-inflammatory properties by inhibiting the expression of proinflammatory cytokines and enzymes, thereby reducing nitric oxide production. Additionally, they have shown promise in selectively targeting cancer cells, exhibiting anti-cancer properties. Furthermore, the active compounds such as quercetin in pepino have been associated with anti-diabetic effects, improving insulin sensitivity and inhibiting insulin resistance. Overall, this review highlights the diverse and significant pharmacological effects of the active compounds found in pepino melon, emphasizing its potential as a valuable functional food.
