Data on polyphenols and biological activity analyses of an Andean tomato collection and their relationships with tomato traits and geographical origin

Abstract

Data provide information about a tomato collection composed of accessions from the Andean Valley, commercial accessions and wild species. Antioxidant metabolites were measured in mature fruits of this collection, and their biological activities were assessed by both in vitro and in vivo methods. In this work, the parameters used to identify and quantify polyphenols compounds in tomato fruit by liquid chromatography coupled to diode array detector and quadrupole time of flight mass spectrometer are described. Moreover, data supporting a procedure to characterize the properties of tomato fruits to revert death by thermal stress in Caenorhabditis elegans are explained in detail. Lastly, principal component analysis and hierarchical cluster analysis of metabolites composition, antioxidant activities (in vivo and in vitro), tomato traits and geographical origin of the tomatoes collection are shown. The data presented here are related to the research article entitled “Hydrophilic antioxidants from Andean Tomato Landraces assessed by their bioactivities in vitro and in vivo” [1].

Quality and Nutritional Evaluation of Regina Tomato, a Traditional Long-Storage Landrace of Puglia (Southern Italy)

“…A recent and remarkable study defines a thorough nutritional profile of several long storage tomato genotypes retrieved in different area of Southern Italy [10]. Studies are available for other tomato landraces of different geographical areas [1,2,11,12], but literature lacks information on RT, a landrace of an unreported geographical area. Starting from these remarks, the aim of the present study was to evaluate the main physical and chemical traits of this heirloom tomato at harvest and after three mounts of storage, simulating the long storage of the ramasole.…”

A Targeted and an Untargeted Metabolomics Approach to Study the Phytochemicals of Tomato Cultivars Grown Under Different Salinity Conditions

“…Among the identified metabolites, chlorogenic acid, rutin, and naringenin were the most prominent compounds found in both cultivars. Previously, similar major metabolites in mature fruits of multiple tomato cultivars were identified using liquid chromatography coupled to a photodiode array detector (PDA) and quadrupole time-of-flight mass spectrometer . The HPLC analysis using diode-array detections showed similar phenolic profiles from both cultivars (JF and RP), although a major difference was observed in individual metabolites (Figure and Table ).…”

“…Previously, similar major metabolites in mature fruits of multiple tomato cultivars were identified using liquid chromatography coupled to a photodiode array detector (PDA) and quadrupole time-of-flight mass spectrometer. 39 The HPLC analysis using diode-array detections showed similar phenolic profiles from both cultivars (JF and RP), although a major difference was observed in individual metabolites (Figure 2 and Table 1). To distinguish between the two cultivars with different treatments, five phenolic compounds (chlorogenic acid, neochlorogenic acid, rutin-Opentoside, rutin, and a naringenin analogue) showed a VIP score >1.0 from the PLS-R model (Supporting Information (SI), Figure S1A).…”

Vegetable Landraces: The “Gene Banks” for Traditional Farmers and Future Breeding Programs

“…These compositions have been associated with the features of the organs, the geographical origin and altitude at which they are found. For example, in high-rise areas of northwestern Argentina, local tomato populations with the highest concentration of antioxidants have been identified [47].…”

“…Recovering and rendering these qualities in adapted landraces to the original communities will contribute to the sustainable maintenance of these varieties [48,49]. For example, tomato landraces are characterized by excellent fruit quality, high content in metabolites [50], antioxidants [20,47] and volatile organic compounds [51]. Landraces and old varieties have a typical flavour that consumers appreciate and demand, although the availability of their seeds is increasingly low [52].…”
