Objectives: The objectives of this study are to screen the phytochemicals, estimate the content of phenolic and flavonoid compounds, and determine the antioxidant capacity of the Sesuvium portulacastrum L. (S. portulacastrum). Methods:The crude bioactives were extracted from the dried powder of S. portulacastrum in an orbital shaker using ethanol, methanol, acetone, hexane, and diethyl ether solvents. Rotaevaporator was used to concentrate the extracts. Total phenolic and flavonoid content was estimated spectrophotometrically using Folin-Ciocalteu and aluminum chloride reagents, respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-Azinobis (3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), hydrogen peroxide (H 2 O 2 ), and ferric reducing antioxidant power (FRAP) assays were used to determine the in vitro antioxidant capacity.Results: Phytochemical screening of the extracts showed the presence of major classes of phytochemicals. Total phenolic content (TPC) expressed as gallic acid equivalents (GAE) ranged from 14.42 (ethanol extract) to 54.05 (diethyl ether extract) mg GAE/g dry weight. Total flavonoid content expressed as quercetin equivalents (QE) ranged from 22.03 (hexane extract) to 56.70 (methanol extract) mg QE/g dry weight. Antioxidant activity determined by different assays is highest in diethyl ether extract. A positive correlation (0.7241≤ r ≥0.8419) was found between the TPC and antioxidant activity determined by DPPH, ABTS, and H 2 O 2 scavenging assays. Furthermore, there is a strong correlation (0.722≤ r ≥0.999) between all the pairs of antioxidant assays. Conclusion:Diethyl ether extract showed the highest TPC and antioxidant potential among all the extracts of S. portulacastrum. Further research has to be done to isolate the pure bioactive compound that has high antioxidant potential.

“…5A and 5B), suggesting that chlorophyll synthesis was not impaired by salt exposure. As suggested by Ramani et al (2006), there may be no need for photoprotection with an increase of total chlorophyll in B. maritima. Chlorophyll fluorescence is a widely used tool to assess salinity impact on the photosynthetic apparatus.…”

Batis maritima is a promising halophyte for sand-dune stabilization and saline-soil reclamation. This species has also applications in herbal medicine and as an oilseed crop. Here, we address the plant response to salinity reaching up to two-fold seawater concentration (0-1000 mM NaCl), with a particular emphasis on growth, water status, mineral nutrition, proline content, and photosystem II integrity. Plant biomass production was maximal at 200 mM NaCl, and the plants survived even when challenged with 1000 mM NaCl. Plant water status was not impaired by the high accumulation of sodium in shoots, suggesting that Na + compartmentalization efficiently took place in vacuoles. Concentrations of Mg 2+ and K + in shoots were markedly lower in salttreated plants, while that of Ca 2+ was less affected. Soluble-sugar and chlorophyll concentrations were hardly affected by salinity, whereas proline concentration increased significantly in shoots of salt-treated plants. Maximum quantum efficiency (F v /F m ), quantum yield of PSII (U PSII ), and electron-transport rate (ETR) were maximal at 200-300 mM NaCl. Both nonphotochemical quenching (NPQ) and photochemical quenching (qP) were salt-independent. Interestingly, transferring the plants previously challenged with supraoptimal salinities (400-1000 mM NaCl) to the optimal salinity (200 mM NaCl) substantially restored their growth activity. Altogether, our results indicate that B. maritima is an obligate halophyte, requiring high salt concentrations for optimal growth, and surviving long-term extreme salinity. Such a performance could be ascribed to the plant capability to use sodium for osmotic adjustment, selective absorption of K + over Na + in concomitance with the stability of PSII functioning, and the absence of photosynthetic pigment degradation.

“…Hence, xerophyte saltbush (Atriplex halimus) RWC L at water stress decreased more significantly than in the presence of NaCl (Martínez et al 2005). In other species of halophytes, RWC L declined slightly after days or months of exposure to saline stress (Ramani et al 2006;Redondo-G omez et al 2007), while at drought reduced RWC L was more noticeable (Turner and Jones 1980;Tezara et al 2003;Pérez-Pérez et al 2007). …”

Stress Responses in Plants

In field conditions the plants are most commonly subjected to simultaneous effects of multiple stresses. The mechanisms of plant tolerance to salinity and drought are physiologically connected and overlapping, but some aspects of physiology and metabolism may differ when in the experiment salt and water stress is used separately or both stresses are used simultaneously. Physiological and biochemical reactions of the plants under combined effect of the drought and salinity are unique, which cannot be directly extrapolated from respective responses to each of these stresses individually. Drought and salinity reduce individually the availability of water for plants. However, the presence of salt in the soil inhibits the rate of the development of drought, enabling the plant to survive in unfavorable period of short-term drought without violation of basic physiological functions. At increased NaCl concentration in the soil during the combined stress, basic physiological and biochemical functions of the plants remain constant until a critical threshold, after which the plants' productivity decreases dramatically. This article shows the features of the combined stress and its difference from the drought and salinity individually.
