“…In sweet basil leaves, not only essential oil components but also 4-(3,4-dihydroxyphenyl)-6,7-dihydroxy-2-naphthoic acid and tanshinone IIA showed different increasing changes upon exposure to N 2 O 5 . These compounds are attracting attention as new therapeutic agents with antioxidant activity against reactive oxygen species in Alzheimer's disease [50][51][52] . Many of the secondary metabolites found in this study are also known to have antioxidant, anti-inflammatory and antiviral effects in humans.…”

Exposure to N2O5 generated by plasma technology activates immunity in Arabidopsis through tryptophan metabolites. However, little is known about the effects of N2O5 exposure on other plant species. Sweet basil synthesizes many valuable secondary metabolites in its leaves. Therefore, metabolomic analyses were performed at three different exposure levels [9.7 (Ex1), 19.4 (Ex2) and 29.1 (Ex3) μmol] to assess the effects of N2O5 on basil leaves. As a result, cinnamaldehyde and phenolic acids increased with increasing doses. Certain flavonoids, columbianetin, and caryophyllene oxide increased with lower Ex1 exposure, cineole and methyl eugenol increased with moderate Ex2 exposure and l-glutathione GSH also increased with higher Ex3 exposure. Furthermore, gene expression analysis by quantitative RT-PCR showed that certain genes involved in the syntheses of secondary metabolites and jasmonic acid were significantly up-regulated early after N2O5 exposure. These results suggest that N2O5 exposure increases several valuable secondary metabolites in sweet basil leaves via plant defense responses in a controllable system.

“…Several new compounds with bioactive potential have been isolated from purslane during recent years, indicating the high antioxidant potential of the species. For example, new alkaloids with anti-inflammatory activity were identified in various studies [ 128 , 129 , 130 , 131 , 132 ], while Wang et al [ 133 ] detected two new lignans with similar properties. These novel compounds could be isolated and incorporated in the design of new drug formulations, nutraceutical and pharmaceutical products, thus increasing the added value of purslane.…”

Soil is an essential resource, and its degradation is challenging modern agriculture, while its impact is expected to increase in the near future. One of the strategies to address this issue is to incorporate new alternative crops able to tolerate arduous conditions, as well as for the use of sustainable agricultural practices in order to recover and/or improve soil health. Additionally, the increasing market for new functional/healthy natural foods promotes the search for potential alternative crop species with promising bioactive compounds content. For this purpose, wild edible plants are a key option because they have already been consumed for hundreds of years in traditional gastronomy and there is well-established evidence of their health-promoting effects. Moreover, since they are not a cultivated species, they are able to grow under natural conditions without human intervention. Among them, common purslane is an interesting wild edible species and a good candidate for integration in commercial farming systems. With worldwide spread, it is able to tolerate drought, salinity and heat stress and is already used in traditional dishes, while it is highly appreciated for its high nutritional value due to its bioactive compound content, especially omega-3 fatty acids. In this review, we aim to present the breeding and cultivation practices of purslane, as well as the effects of abiotic stressors on yield and chemical composition of the edible parts. Finally, we present information that helps to optimize purslane cultivation and facilitate its management in degraded soils for their exploitation in the existing farming systems.

“…Thus, exploring the phytochemical profiles of purslane has been the subject of intense investigation over the last few decades, yet advances are still constantly occurring. Therefore, in this section, major classes of bioactive compounds isolated from purslane such as polysaccharides, alkaloids (1-79), flavonoids (80)(81)(82)(83)(84)(85)(86)(87)(88)(89)(90)(91), and other phytochemicals (92)(93)(94)(95)(96)(97)(98)(99)(100)(101)(102)(103)(104)(105)(106)(107)(108)(109) were compiled and discussed.…”

Portulaca oleracea L., commonly known as purslane, is a worldwide weed species belonging to the family Portulacaceae and has been known as "Global Panacea". As one of the most widely consumed green vegetable and medicinal plants around the world, it has recently been re-evaluated as a potential "new crop" due to the properties that differentiate it as one of the best vegetable sources of omega-3 fatty acid (α-linolenic acid), as well as a variety of nutrients and phytochemicals. Accordingly, emerging research has found that purslane exhibits health-promoting properties like anti-inflammatory, anti-hyperglycemic, antioxidant, neuroprotective, and immunomodulatory. These findings suggest that this species possesses a potential using as a dietary supplement beyond potherb and traditional medicine. This review systematically summarizes the up-to-date research carried out on purslane, which includes the nutritional compositions, bioactive compounds, and health benefits it exerts as well as limitations, challenges, and future directions of research. Finally, we hope that this review would provide purslane with a comprehensive reference and future scope as functional and health-promoting food for disease prevention and treatment.
