“…Characterization of trans-pcoumaric acid glucoside was done by UV, CIMS, EIMS and NMR. The m/z 326 was observed by use of NH 3 -CIMS, and the glucoside linkage was confirmed by 1 H NMR (Schuster et al 1986). The cis-isomer of p-coumaric acid glucoside was converted to the trans form by warming with dilute HCl.…”

Changes in the metabolism of several types of phenolics in the pulp and pericarp of tomato (Lycopersicon esculentum) fruit var. Ailsa Craig and Pik-Red were related to the stage of development. The highest levels of chlorogenic acid were found in the pulp and pericarp at the earliest stage of fruit development, and quantities declined rapidly during fruit ripening. Levels of rutin, found only in the pericarp, followed a similar pattern of change. The p-coumaric acid conjugate of rutin was found in low levels through fruit growth and ripening. High levels of p-coumaric acid glucoside were detected in the pulp only as the fruit matured with no rapid decline in levels during ripening. The decline of chlorogenic acid and rutin levels during fruit ripening paralleled the decline in indole-3-acetic acid levels measured previously in the pericarp tissues of these two varieties of tomato fruit during maturation. These phenolics are among those that have been suggested as regulants of auxin metabolism.

“…3). 24, 40 For this compound esterification has taken place at the 5‐ position of the quinic acid moiety, and hence chlorogenic acid is defined as 5‐caffeoyl quinic acid (5‐CQA) 41. This is the opposite of older conventions which defined chlorogenic acid to be the isomer that had ester bonding at the 3‐ position of the quinic acid moiety 42.…”

Review of flavonoids and other phenolics from fruits of different tomato (Lycopersicon esculentum Mill.) cultivars

BACKGROUND: Tomato, one of the most important vegetables worldwide, contains a range of flavonoids and phenolic acids in addition to lycopene, which are regarded as potentially useful compounds with respect to health benefits. Composition data in fresh tomatoes vary due to genetic and environmental factors and cultural practices. Breeding programs aim to produce tomatoes with enhanced levels of flavonoids and other phenolics.

“…In fact, this compound may correspond to caffeic acid-4-O-β-D-glucoside reported before in L. esculentum leaves. [16] Compound 1 coeluted with another one differing in 16 amu and exhibiting a similar fragmentation pattern (Table 1). Thus, we believe that compound 2 corresponds to p-coumaroyl-hexoside acid (2).…”

High-performance liquid chromatography-diode array detection-electrospray ionization multi-stage mass spectrometry (HPLC-DAD-ESI-MS(n)) is considered to be a very valuable tool for the characterization of compounds found in trace amounts in natural matrices, as their previous isolation and clean-up steps can be avoided. Micro-scale separation increases the potential of this analytical technique, allowing the determination of compounds in reduced samples. Spodoptera littoralis represents a major challenge to Solanaceae plants, as it is one of the most deleterious pests. The S. littoralis/Lycopersicon esculentum system was studied for the first time concerning glycoalkaloids and phenolics. Using HPLC-DAD-ESI-MS(n) we were able to characterize 15 phenolic compounds in L. esculentum leaves. Nine of them are reported for the first time. Some differences were found between leaves of cerasiforme and 'Bull's heart' varieties. However, in the materials of S. littoralis (larvae, adults, exuviae and excrements) reared in both L. esculentum leaves no phenolics were identified. α-Tomatine was the main glycoalkaloid in the host plant. The glycoalkaloid composition of the different S. littoralis materials was distinct, with α-tomatine and dehydrotomatine being the main detected compounds in larvae and excrements. These results add knowledge to the ecological interaction in this insect/plant duo, for which it is hard to obtain considerable sample amounts.
