Lipophilic Metabolites of Spartina maritima and Puccinellia maritima Involved in Their Tolerance to Salty Environments

Abstract

Spartina maritima and Puccinellia maritima are two fascinating but underexplored halophytic species, and herein, the chemical profile of their hexane extracts is described. Terpenoids and sterols were the most abundant chemical groups in both species. The second dominant class was alcohols and the third esters of fatty acids. The chemical lipophilic profile of both S. maritima and P. maritima is herein reported for the first time. Through the accomplished data, it is possible to conclude that these species are rich in essential compounds that can be relevant to endorse their use as nutraceuticals. Furthermore, through a principal component analysis, a clear differentiation between the taxa was achieved, which indicates that their response to salinity stress is different. That fact was confirmed by the pathway enrichment analysis, which showed that the induced changes in metabolic pathways vary in each species.

Chemical profile and antioxidant activity of Sesbania bispinosa (Jacq.) W. Wight aerial parts and seeds extracts

“…The sugars are also found in a high percentage; naturally, turanose is the one that contributes more, but several others were also found. In fact, this compound accumulation is also associated with the plant response to environmental stress (Faustino et al., 2020).…”

“…Another noticed difference is the percentage of carboxylic acids, both small and fatty ones, which are higher in seeds, being citric acid, the more representative one, with 8.31% (Table 3). It is important to focus that these compounds’ presence is also associated with the plant response to the soil salinity (Faustino et al., 2020).…”

Chemical Composition and Antioxidant, Antiparasitic, Cytotoxicity and Antimicrobial Potential of the Algerian Limonium Oleifolium Mill. Essential Oil and Organic Extracts

“…To our best knowledge, L. oleifolium essential oil and organic extracts were not studied. So, in this context and as part of a continuous study on Algerian medicinal plants, [27–29] GC/MS and GC‐FID analyzes were employed to establish the chemical profile of L. oleifolium aerial parts essential oil. This study aimed as well to assess the essential oil, methanolic, CHCl 3 , AcOEt and BuOH extracts antioxidant, antimicrobial, antiprotozoal activities.…”

Aglaomorpha quercifolia (L.) Hovenkamp & S. Linds a Wild Fern Used in Timorese Cuisine

“…Some of the terpenoids found in A. quercifolia rhizomes are commonly found in plants, including some phytosterols found in our previous works [ 32 , 38 ]. Cycloartane triterpenoids’ natural occurrence is also vast through the plant kingdom [ 39 ], being cycloartenol the most recognized due to its rule in the phytosterols biosynthesis [ 40 ] and consequently in the regulation of important plant functions [ 41 ].…”
