“…The peel and pulp of citrus fruits and tomatoes contain phenolic and flavonoid compounds. Although it was previously reported that orange peel and cherry tomato contain significant levels of polyphenolic compounds ( 49 , 55 ), this study is the first to measure the total phenolic and flavonoid contents of oranges and tomato juice powders. The levels of polyphenolic compounds in unshiu mikan, sweet orange, and boiled tomato were 7.74, 5.48, and 9.66 mg/g, respectively, whereas the flavonoid contents were 1.83, 1.0, and 0.90 mg/g.…”

The aim of this study was to investigate the protective effects of juice powders from sweet orange [Citrus sinensis (L.) Osbeck], unshiu mikan (Citrus unshiu Marcow), and mini tomato (Solanum lycopersicum L.), and their major flavonoids, hesperidin, narirutin, and rutin in tert-butyl hydroperoxide (t-BHP)-induced oxidative stress in HepG2 cells. The increased reactive oxygen species and decreased glutathione levels observed in t-BHP-treated HepG2 cells were ameliorated by pretreatment with juice powders, indicating that the hepatoprotective effects of juice powders and their major flavonoids are mediated by induction of cellular defense against oxidative stress. Moreover, pretreatment with juice powders up-regulated phase-II genes such as heme oxygenase-1 (HO-1), thereby preventing cellular damage and the resultant increase in HO-1 expression. The high-performance liquid chromatography profiles of the juice powders confirmed that hesperidin, narirutin, and rutin were the key flavonoids present. Our results suggest that these fruit juice powders and their major flavonoids provide a significant cytoprotective effect against oxidative stress, which is most likely due to the flavonoid-related bioactive compounds present, leading to the normal redox status of cells. Therefore, these fruit juice powders could be advantageous as bioactive sources for the prevention of oxidative injury in hepatoma cells.

“…From a nutraceutical viewpoint, tomato is recognized as one of most important suppliers of carotenoids and phenolic acids, whose content contributes to the antioxidant capacity of this vegetable [33], and the shift in their concentration during ripening is one of the major changes accompanying the improvement of fruit palatability. The S 1 fruits showed compositional evidences of backwarded ripening process compared to the S 2 ones, resulting from a higher antioxidant activity and a lower concentration of the main carotenoids.…”

The present experiment addressed the effects of two harvest stages, namely breaker (S1) and turning (S2), on compositional and sensory profile of grafted, greenhouse elongated tomatoes cv. “Sir Elyan”. The rootstocks “He-Man”, “Interpro”, and “Armstrong” were used. The S1 fruits showed a higher dry matter content, firmness and titratable acidity when compared to the S2 ones (by 6%, 3%, and 15%, respectively). They showed, also, the highest L-ascorbic acid concentration and antioxidant activity. Differently, soluble solid content, lycopene and β-carotene increased in the S2 fruits (by 4%, 92%, and 26%, respectively). Excepting methyl salicylate, all the volatiles detected peaked in the S2 fruits, which were scored by panelists as sweeter and more flavorful than the S1 ones. Among the rootstock genotypes, “He-Man” promoted fruits firmness, carotenoids concentration and antioxidant activity, irrespective of the harvest stage. “Interpro” enhanced the sensory attributes of the S1 fruits in terms of bitterness, sourness, sweetness and flavor. Differently, sweetness, sourness, and tomato flavor of the S2 fruits were promoted by “Armstrong”. The results highlight the influence of rootstock genotype on the nutraceutical and sensorial profile of “Sir Elyan” fruits harvested at early ripening stages.

“…In antidiarrheal screening, castor oil is known to cause water and electrolyte permeability changes in the intestinal mucosal membranes, resulting in fluid and watery luminal content that flow rapidly through the small and large intestines [49]. The induction of diarrhea by castor oil is attributed to its active ingredient ricinoleic acid which stimulates the production of several inflammatory mediator substances that include prostaglandins, nitric oxide, and platelet activating factor, cAMP, histamine and tachykinins [50].…”

Background Hopea Odorata, locally known as Telsur (Bangladesh), has some traditional uses as folk medicine. This study aims to investigate the antioxidant, antidiarrheal, hypoglycemic and thrombolytic activities of H. odorata leaf extracts as new therapeutic prospects predicting the activity of some of the isolated compounds of this plant.MethodsLeaves of Hopea odorata was extracted with pure methanol (MEHO), ethanol (EEHO) and water (AEHO). The extract was tested for antioxidant activity by using reducing power and H2O2 scavenging assay. Antidiarrheal effects were assayed by three standard methods of bioassay: Castor oil-induced diarrhea, Castor oil induced enteropooling and gastrointestinal transit test. Hypoglycemic effect was determined by normoglycemic model of mice. Thrombolytic activity was evaluated by clot lyses test for human and mice blood. In silico PASS prediction was applied for phytoconstituents namely Balanocarpol, Hopeaphenol and Ampelopsin H isolated from this plant. ResultAmong the all extracts, MEHO exhibited strong antioxidant activity in both reducing power and H2O2 scavenging assay. Phenol content of MEHO was 297.22 ± 0.78 mg/g and flavonol content was 91.53 ± 1.82 mg/g. All the experiment of extracts at dose of 200 and 400 mg/kg and the standard drug loperamide (5 mg/kg) showed significant (p < 0.001) inhibition against castor oil induced diarrhea and castor oil induced enteropooling in mice. There were also significant (p < 0.01) reduction in gastrointestinal motility in the charcoal meal test. Leaf extract showed no significant (P < 0.01) decrease of blood glucose compared to Glibenclamide in normoglycemic mice. Using an in vitro thrombolytic model, MEHO showed the highest and significant clot lysis of human and mice blood compared to Streptokinase. PASS predicted the wide range of antioxidant, free radical scavenger, Nitric oxide scavenger, cardioprotectant, hepatoprotectant, thrombolytic, fibrinolytic, antibacterial, antifungal, anticarcinogenic, anthelmintic and anti-inflammatory activity of examined phytoconstituents.ConclusionThese findings suggest that the plant may be a potential source of new antidiarrheal, thrombolytic and antioxidative agents but it is found to have no antidiabetic capability. PASS prediction matched with present study for the extracts. Further study needs to identify the PASS predicted biological actions of the phytoconstituents.Electronic supplementary materialThe online version of this article (doi:10.1186/s12906-016-1461-x) contains supplementary material, which is available to authorized users.

Abstract: A significant effect of temperature on the antioxidant capacity was observed. After this treatment the industry might introduce some advances in the processing of tomatoes, preserving the main nutritive characteristics and saving the products as semi-dried.
