“…Santa Rosa) and nectarine (Prunus persica var. Nectarin) (Gil, et al, 2002;Cantín, et al, 2009;Belhadj, et al, 2016). These high concentrations of phenolics were significantly correlated (positively) with DPPH and/or ABTS radical scavenging activity, except for OR accession, which was not significant neither for DPPH nor for ABTS radical scavenging activity.…”

“…The total phenolic content was determined using the Folin-Ciocalteu method. [13] Total phenolic values are expressed as milligrams of gallic acid equivalents per gram of fresh weight (mg of GAE/g FW). The calibration curve was prepared with gallic acid solutions ranging from 0 to 100 mg/l.…”

“…][ Therefore, the plant effective constituents must be identified and analyzed to gain a clearer understanding of its potential. It is also important to determine the optimum stage of maturation for harvest in order to obtain the maximum of nutritional and therapeutical benefits since it's well‐known that the chemical composition of plants undergoes various changes throughout the maturation process . The aim of this work is to provide a first detailed comparative phytochemical screening of L .…”

The present work aimed to determine the antioxidant and antiproliferative potential of Luffa cylindrica fruits collected at two different maturation stages and to identify and compare their functional components composition. The MeOH extracts of L. cylindrica fruits harvested at 60 - 65 days after seeding (S1) and 85 - 90 days after seeding (S2) were investigated for their antioxidant activity using various assays. Furthermore, the antiproliferative activity of the extracts against HeLa human cervical cancer cells was explored with xCELLigence real time cell analyzer, while the effect of the samples on the membrane integrity of the same cell line was assessed using LDH cytotoxicity leakage assay. Ultimately, the phytochemicals were analyzed using GC/MS and HPLC/TOF-MS. The S1 sample had higher contents and more diversity in the phenolic compounds composition than S2. Furthermore, the S1 extract showed the highest antioxidant and antiproliferative activity, while the S2 extract had higher cytotoxicity towards HeLa cells. The findings revealed that the time of harvest has a big impact on the phytochemicals content and activity and that harvesting L. cylindrica at an early stage before the beginning of the development of the cellulose fibrous system is recommended for a rich phytochemical composition and efficient antioxidant and antiproliferative activities.

The metabolomic content determines many of the important features of a fruit, such as its taste, flavor, color, nutritional value, and abiotic or biotic resistance. Peach (Prunus persica (L.) Batsch) is one of the best genetically characterized species used as a model for Rosaceae, the drupes of which are a source of minerals, vitamins, fiber, and antioxidant compounds for healthy diets around the world. During the last few years, a great advance in the analysis of the metabolic diversity and reconfiguration in different peach varieties in response to developmental and environmental factors has occurred. These studies have shown that the great phenotypic diversity among different peach varieties is correlated with differential metabolomic content. Besides, the fruit metabolome of each peach variety is not static; on the contrary, it is drastically configured in response to both developmental and environmental signals, and moreover, it was found that these metabolic reconfigurations are also variety-dependent. In the present review, the main sources of metabolic diversity and conditions that induce modifications in the peach fruit metabolome are summarized. It is postulated that comparison of the metabolic reconfigurations that take place among the fruits from different varieties may help us better understand peach fruit metabolism and their key drivers, which in turn may aid in the future design of high-quality peach fruits.
