Diversity for chemical composition in a collection of different varietal types of tree tomato (Solanum betaceum Cav.), an Andean exotic fruit

Abstract

We evaluated 23 tree tomato (Solanum betaceum) accessions from five cultivar groups 24 and one wild relative (S. cajanumense) for 26 composition traits. For all traits we found 25 highly significant differences (P<0.001) among the materials studied. The high diversity 26 found within S. betaceum for composition traits was matched by a high diversity within 27 each of the cultivar groups. We found that sucrose and citric acid were the most 28 important soluble sugar and organic acid, respectively, in tree tomato. Fruit in the 29 anthocyanin pigmented (purple) group had a carotenoid content similar to that in the 30 yellow-orange cultivar groups. Total phenolic content was significantly correlated 31 (r=0.8607) with antioxidant activity. Analyses of mineral content showed that tree 32 tomato is a good source of K, Mg, and Cu. Multivariate principal components analysis 33 (PCA) confirmed that an important diversity exists within each cultivar group. The 34 results we have obtained indicate that the high diversity found within the tree tomato 35 could be exploited for selection and breeding for developing the tree tomato as a 36 commercial crop. 37 38

Chemical profiling and pharmaco‐toxicological activity ofOriganum sipyleumextracts: Exploring for novel sources for potential therapeutic agents

“…A linear relationship was observed between the antioxidant effect of water extract and its TPC which indicates that high content of phenols confers greater antioxidant activity. This conclusion was also agreed by a number of previous studies which found that plants extracts rich in phenols tend to show high antioxidant property (Acosta‐Quezada et al, ; Barbouchi, Elamrani, El Idrissi, & Choukrad, ; Islam, Yu, & Xu, ).…”

“…Increased reactive oxygen/nitrogen species (ROS/RNS) have long been associated to oxidative damages to macromolecules, including nucleic acids, proteins and lipids (Uttara, Singh, Zamboni, & Mahajan, 2009). In particular, lipid peroxidation can be considered as a key factor in colon inflammation (Achitei et al, 2013). To this regard, the evaluation of colon nitrite level is a validated tool to measure the synthesis of NO, which is deeply involved in colon tissue damage (Goggins et al, 2001).…”

Chemical profile, antioxidant, and enzyme inhibitory properties of two Scutellaria species: S. orientalis L. and S. salviifolia Benth

“…Furthermore, the trend observed in the current study revealed that the aqueous extracts of the tested plants showed the highest antioxidant activity in most assays, which conforms with the highest content of phenolics and flavonoids. In fact, some previous studies have proven that the antioxidant activity of plant extracts is positively correlated with their polyphenolic content …”

Andean berries from Ecuador: A review on Botany, Agronomy, Chemistry and Health Potential

“…However, the expansion of this crop is limited by factors such as the lack of clear differentiation among varieties, low fruit quality (heterogeneity and phytosanitary problems), the use of inappropriate varieties or replacement of local varieties by materials from other origins not adapted [64]. Some works studying genetic diversity have indicated the existence of considerable variability and that it is possible to select materials with characteristics more suitable for fruit market [19,[64][65][66]; however, more investigations related to its conservation and genetic improvement are needed [64,67].…”

“…Nevertheless, while health-related properties and chemical composition of berries commonly found in North America and Europe have been widely explored; those natives from South America need more information. Several scientific reports have pointed out the therapeutic potential of certain plants and foods from this area, for instance Rubus glaucus B., Physalis peruviana L. and Solanum betaceum C. are among the relevant ones [16][17][18][19][20][21][22][23].…”
