“…Rutin is a powerful antioxidant, known for its capacity to strengthen the blood cell walls [33], with antitumor, antibacterial and antiviral [34], antioxidant and anticarcinogenic properties [35]. Moreover, rutin has been reported to help in collagen production and to enhance utilisation of vitamin C [36], which is present in significant amounts in tamarillo (25 mg/100 g) [37]. Jang, Wang, Lee, Lee and Lim [38] reported that kaempferol-3-rutinoside, known as a powerful α-glucosidase inhibitor, owned anti-adipogenic potential, which may act as an anti-obesity agent.…”

This study examined phenolics and anthocyanins present in Amber, Laird’s Large and Mulligan cultivars of tamarillo that were cultivated in Whangarei, Northland of New Zealand. Samples were further separated by their tissue types, peel and pulp. Using LC-MS/MS, twelve polyphenols were quantified and six (ellagic acid, rutin, catechin, epicatechin, kaempferol-3-rutinoside and isorhamnetin-3-rutinoside) were detected for the first time in tamarillo. Mulligan cultivar showed the highest amounts of phenolic and anthocyanin compounds and the highest antioxidant activity. Phenolic compounds were mostly synthesized from shikimic acid route, and chlorogenic acid dominated the profile regardless of cultivar and tissue types. Anthocyanin profile was dominated by delphinidin-3-rutinoside in pulp. Higher amounts of anthocyanins were detected in this study, which may be explained by favourable growth conditions (high light intensity and low temperature) for anthocyanin biosynthesis in New Zealand. Higher antioxidant activity and total phenolic content in peels than in pulps were found when assessed by Cupric Ion-Reducing Antioxidant Capacity (CUPRAC), Ferric Reducing Ability of Plasma (FRAP) and Folin–Ciocalteu assays, and a positive correlation (r > 0.9, p ≤ 0.01) between the three assays was observed. Current findings endorse that tamarillo has a great bioactive potential to be developed further as a functional ingredient with considerable levels of antioxidant compounds and antioxidant activity.

“…The pulp of the tamarillo, which constitutes 85% of the whole fresh fruit, is consumed fresh or preserved by pickling, stewing, or drying for later use as a condiment. Tamarillos are good sources of dietary fiber, vitamins A, C, and E, as well as some minerals, carotenoids and anthocyanins [14,16,17]. Several studies have attempted to explore proximate compositions [16,18], sugars and organic acids [14,19], pigments [20][21][22], phenolics and anthocyanins [23], carotenoids [20,24,25], vitamins [16,26] and minerals [27] in tamarillos.…”

Amber (yellow), Laird’s Large (red) and Mulligan (purple–red) cultivars of New Zealand tamarillo fruit were separated into pulp (endo- and mesocarp) and peel (exocarp), and analyzed by liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) for carotenoids, α-tocopherol and ascorbic acid contents. Fresh Mulligan pulp had the highest content of β-carotene (0.9 mg/100 g), α-tocopherol (1.9 mg/100 g), and ascorbic acid (28 mg/100 g). Higher concentrations of β-carotene and ascorbic acid, and lower concentrations of α-tocopherol were detected in pulps compared with peels. Compared with standard serves of other fruit, tamarillo had the highest β-carotene (9–20% RDI (recommended dietary intake)/serve), high ascorbic acid (67–75% RDI/serve), and α-tocopherol (16–23% adequate intake/serve). All cultivars had diverse carotenoid profiles dominated by provitamin A carotenoids (β-carotene and β-cryptoxanthin) and xanthophyll carotenoids (lutein; zeaxanthin and antheraxanthin). Favorable growth conditions (high light intensity and low temperature) may explain the higher antioxidant vitamin content in New Zealand tamarillos compared to those from other countries. Tamarillo peels may be used as natural food coloring agent to reduce waste and deliver sustainable production.

“…), also familiarly known as tamarillo, is a neglected, fast-growing, promising small fruit crop native to the Andean region [1] and widely cultivated in the tropics and subtropics of South America, New Zealand, Australia and India, etc. [2][3][4]. As fresh fruit, it is an important and nutrient dense food source of human diets containing plenty of sugars, organic acids, minerals, ascorbic acid, provitamin A, carotenoids, vitamin B 6 and phenolics [5][6][7]; as processed product, it represents an important export commodity and stimulates both the local and overseas demand in fruit markets [3].…”

“…Previous studies mainly focused on its biochemical property [5,6], phenology [8], and reproductive biology, including ower and pollen morphology, physiology, fruit characteristics, intraspeci c hybridization and genetic diversity [4]. Despite the importance and recent progress, reference genome and transcriptome of tree tomato are not available, which severely impeded in-depth functional genomics, molecular genetics and genetic-assisted breeding of tree tomato.…”

Background: Tree tomato (Cyphomandra betacea (Cav.) Sendtn.) is a neglected, fast-growing, promising small fruit crop which provides a rich source of nutrition for human consumption. However, the transcriptome atlas of this important species is still lacking.Results: In this study, RNA samples from a broad diversity of tissues (roots, leaves, stems, flowers and fruits) of tree tomato were sequenced using Pacific Biosciences’ long-read single-molecule real-time sequencing technology. A total of 308699 full-length non-chimeric sequences with a mean length of 1005 bp and an N50 length of 1974 bp were obtained from our multi-tissue normalized cDNA libraries. A total of 140327, 104294, 135138, 78300, 53520, 152310 and 53520 transcripts were functionally annotated using Nr, Swiss-Prot, KEGG, KOG, GO, Nt and Pfam databases, respectively. Gene structural characteristics of the full-length transcriptome of tree tomato was subsequently investigated, including the predication of coding sequence and the identification of transcription factor families, long non-coding RNA and simple sequence repeat (SSR) marker. Thirty primers were randomly selected to evaluate the application of SSR markers, 23 of which obtained successfully amplification.Conclusions: This is the first confident characterization of FL transcriptome profiling of tree tomato. The large-scale and high-quality transcriptome atlas and SSR molecular markers provided in the present study will facilitate further genetic studies of this important species.
