Abstract

Cocona fruits are a popular food and medicinal fruit used mainly in the Amazon and several countries of South America for the preparation of several food products such as drinks, jams and milk shakes. In this study five ecotypes of cocona native to Peru have been studied regarding their nutritional and antioxidants values plus antihyperlipidemic activities. Seventy bioactive compounds have been detected in Peruvian cocona ecotypes including several phenolic acids, aminoacids and flavonoids; of those six were spermidines, (peaks 1, 2, 25, 26, 38 and 39), thirteen were aminoacids, (peaks 3–9, 11–13, 16, 17, 22–24), eighteen flavonoids (peaks 28, 30–32 45,46, 48–53 56, 57, 61 and 64–66), twelve were phenolics (peaks 19, 21, 27, 29, 34, 35, 36, 42, 43, 44, 54, and 59), two carotenoids, (peak 62 and 63), eight were lipid derivatives (peaks 37, 55, 58, 60 and 67–70), one sugar (peak 47), four terpenes (peaks 33, 40, 41 and 47), two amides, (peaks 10 and 18), one aldehyde, (peak 15), and three saturated organic acids, (peaks 4, 5 and 20). Hypercholesterolemic rats administered with pulp of the ecotypes CTR and SRN9 showed the lowest cholesterol and triglyceride levels after treatment (126.74 ± 6.63; 102.11 ± 9.47; 58.16 ± 6.64; 61.05 ± 4.00 mg/dL, for cholesterol, triglycerides, high-density lipoprotein and low-density lipoprotein respectively, for the group treated with SRN9 pulp, and 130.09 ± 8.55; 108.51 ± 10.04; 57.30 ± 5.72; and 65.41 ± 7.68 mg/dL, for cholesterol, triglycerides, HDL and LDL lipoproteins respectively for the group treated with CTR pulp). The ecotypes proved to be good sources of natural antioxidants and their consumption represent an alternative for the prevention of atherosclerosis.

Highlights

Changes, as well as with the process of domestication of the species; little is known about its chemical composition and the implications of the terroir and climate in its morphology and nutrient and health beneficial properties
(126.74 ± 6.63; 102.11 ± 9.47; 58.16 ± 6.64; 61.05 ± 4.00 milligrams per deciliter (mg/dL), for cholesterol, triglycerides, high-density lipoprotein (HDL) and low-density lipoprotein (LDL) respectively, for the group treated with SRN9 pulp, and 130.09 ± 8.55; 108.51 ± 10.04; 57.30 ± 5.72; and 65.41 ± 7.68 mg/dL, for cholesterol, triglycerides, HDL

Summary

Introduction

UHPLC-PDA-ESI-OT-MS; Solanaceae; nutritional values; In recent decades, global interest has increased in search of the chemical composition and biological activities of natural sources since many of the compounds present in biological sources such as local plants and marine organisms are important for the protection of human health. The fruit of cocona (Solanum sessiliflorum Dunal; Solanaceae) are native of the Amazonian tropic. The common name of the fruit in Spanish or Portuguese speaking countries is cocona, topiro or cubiu, and is known as “Orinoco apple” and “peach tomato” in English speaking countries. It is an endemic species to Amazon cultivated by natives and settlers in agroforestry arrangements and chagras in their settlement sites which improves it on a traditional food from this area
