“…Besides the 90% of water in the pulp, what makes it a very natural source of water for human hydration, watermelon is a natural source of antioxidants compounds, such as lycopene (42.7-102.4 mg kg ), most important bioactive compounds present in the pulp (Tlili et al, 2011), that prevent oxidant damages in cells (Melo et al, 2006;Costa et al, 2012). However, fruits chemical composition may be affected by a series of factors, including its genetics, environment conditions and cultural practices (Cao et al, 2015).…”

Effects of doses and phosphorus application forms were studied on the postharvest quality in seedless watermelon hybrid 'Style'. For this, an experiment was conducted in Upanema/RN, Brazil, during the period of September to December 2013, in a randomized block at factorial scheme 5×2 constituting of five phosphorus doses applied in foundation (0, 76, 168, 275 and 397 kg ha -1 of P 2 O 5 ) and foundation + fertigation (0+50, 26+50, 118+50, 225+50, 347+50 kg ha -1 of P 2 O 5 ) with four replications. Fruit harvested at commercial maturity (78 days after sowing) were evaluated by average fruit weight (AFW), pulp firmness (PF), chroma index, hue angle, soluble solids content (SS), titratable acidity (TA), maturation index (MI), total phenols content (TP), vitamin C (VC), total sugars content (TS), reducing sugars content (RS) and pH. Among the quality parameters evaluated phosphorus application forms did not affect physical characteristics of fruit, but combination of application via foundation + fertigation increased VC, TS and MI. There was interactive effect of dose and phosphorus application form for the SS, TA, pH and TP. The dose of 50 kg P 2 O 5 ha -1 applied only in fertigation significantly increased values of SS, TA and TP. It is concluded that low doses of P in cultivation and its application via foundation and fertigation improved the main quality characteristics of 'Style' watermelon.

“…Meanwhile, the organic solvent acetone was used to extract the lipophilic compounds preferentially carotenoids, especially lycopene that is representing this class in watermelon juice. These same solvents were used in previous studies in the literature for the extraction of hydrophilic and lipophilic compounds present in samples of watermelon juice for studies of antioxidant activity (Ilahy et al ., ; Tlili et al ., ,b).…”

Summary The aim of this study was to evaluate the potential of nanofiltration for the concentration of bioactive compounds of watermelon juice. Lipophilic and hydrophilic antioxidant activities were determined through two assays, ferric reducing antioxidant power and DPPH. The content of lycopene, flavonoids and total phenolic in the concentrate samples increased with the increase in the volume reduction factor. Volume reduction factor of three showed the best performance of concentration, generating the highest values for lycopene, flavonoid and total phenolic contents. Average permeation flux was 2.3 L h−1 m−2, with continuous extraction of the concentrate at a volumetric reduction ratio of three. Lycopene showed the highest rejection coefficient (0.99), followed by flavonoids (0.96) and total phenolic content (0.65). The hydrophilic antioxidant activity values in both assays were higher than the lipophilic antioxidant activity values. A highly significant correlation was noted between the contents of flavonoids, phenolic compounds, ascorbic acid, and lycopene and their antioxidant potential in both lipophilic and hydrophilic fractions.

Quality and Efficacy of Tribulus terrestris as an Ingredient for Dermatological Formulations

Tribulus terrestris L. (Zygophyllaceae) is an annual plant commonly known as Puncture vine. It is dramatically gaining interest as a rich source of saponins. T. terrestris is a promising ingredient for many industries and recent patents on dermatological applications support the use of this plant for cosmetics and hygiene. Nonetheless problems arise in the selection of the material to be used. The extracts of different origins may differ substantially. Natural speciation processes normally influence 'variations' in wild-crafted medicinal plants. The genus Tribulus is emblematic. Taxonomic status of T. terrestris is complicated by the wide geographical distribution leading to high levels of genetic polymorphism. Being aware of such variability we selected 3 commercial Tribulus extracts and compared their biological effect on Candida albicans with the effect produced by an extract from local plants (South of Apulia, Italy). One of the commercial extracts with the best anti-candida performance was used to substitute triclosan in a detergent formulation and it proved to improve the product performance in the control of potentially pathogenic skin flora such as C. albicans.
