“…Under drought conditions (Table 2), increases in quantities of carotenoids and non-enzymatic antioxidants were reported in many studies [53,54]. For instance, the results obtained by Sedghi et al [55] showed that, the concentration of carotenoids; namely lycopene and β-carotene, increased under water deficit in Calendulla officinalis compared with control plants. Similarity, carotenoids were accumulated in drought-stressed Rosmarinus officinalis [56].…”

The present study provides a detailed description of the phytochemical analysis, physiological features and biological activities of four selected plant species, namely Calligomum polygnoides subsp. comosum and Nicotiana glauca collected from the coastal desert in the Delatic Mediterranean Sea, as well as Hyoscyamus muticus and pulicaria undulate subsp. Undulata collected from the inland desert in Wadi Hagul and Wadi El-Molaak in the North of Eastern Desert in Egypt. The obtained results showed that, the studied plant species are relatively rich in proximate constituents, elements and bioactive secondary metabolites. Hyscyamus muticus leaves appeared to accumulate ABA in highest magnitude if compared to Nicotiana glauca, Pulicaria undulata subsp. undulata and Calligonum Polygonoides subsp. comosum. Antioxidant enzymes as well as DPPH scavenging activities in leaves of Nicotiana glauca, found to be the highest activity in catalase, perioxidase and polyphenol oxidase as well as antioxidant activity and IC50 as compared to other selected plant species. On the other hand, Calligonum polygonoides subsp. comosum attained the highest activity of phenylalanine ammonia lyase and the weakest antioxidant activity with IC50 value (0.29 mg ml -1 ).The highest ratio of total saturated fatty acids to unsaturated fatty acids was recorded in Nicotiana glauca, while the lowest one was found in Calligonum polygonoides subsp. comosum. Concerning the biological activities, the methanolic extract of Nicotiana glauca showed the highest antioxidant activity, while the extract of Calligomum polygnoides subsp. comosum exhibited the weakest antioxidant activity. The methanolic extract of Pulicaria undulata subsp. undulata showed the highest antimicrobial activity, followed by the extracts of Hyoscyamus muticus, Nicotiana glauca and finally by Calligomum polygnoides subsp. comosum. On the other hand, the aqueous extract of Nicotiana glauca showed, the highest inhibition percentages of seed germination, radical growth and plumule growth of summer weed Portulaca oleracea, followed by the extracts of Pulicaria undulata subsp. undulata, Hyoscyamus muticus and finally by Calligomum polygnoides subsp. comosum. Therefore, it can be concluded that, the selected plant species in the present study are obviously considered as tolerant species against extreme drought and salinity. These species could be also used as natural renewable resources in numerous beneficial purposes such as medicine industry, natural antioxidants, antimicrobial agents and allopathic potential for biological control of weeds.

“…Carotenoids (Car) are auxiliary pigments essential for photosynthesis, and their response to drought is somewhat different from that of Chl. Many studies have shown that drought increases Car content (Sedghi et al, 2012;Saeidnia et al, 2018), and plants of droughttolerant genotypes maintain higher Car content than droughtsensitive genotypes under drought (Shah et al, 2011). It has also been reported that drought significantly reduces Car content (Mibei et al, 2017;Khodabin et al, 2020).…”

Changes in global climate and precipitation patterns have exacerbated the existing uneven distribution of water, causing many plants to face the alternate situation of drought and water flooding. We studied the growth and physiological response of the wetland plant Artemisia selengensis to drought and rehydration. In this study, Artemisia selengensis seedlings were subjected to 32.89% (SD), 47.36 % (MD), 60.97% (MID), and 87.18 % (CK) field water holding capacity for 70 days, followed by 14 days of rehydration. The results showed that drought inhibited the increase of plant height, basal diameter, and biomass accumulation under SD and MD, but the root shoot ratio (R/S) increased. Drought stress also decreased the content of total chlorophyll (Chl), chlorophyll a (Chl-a), chlorophyll b (Chl-b), and carotenoid (Car). Soluble sugar (SS) and proline (Pro) were accumulated rapidly under drought, and the relative water content (RWC) of leaves was kept at a high level of 80%. After rehydration, the plant height, basal diameter, biomass, and R/S ratio could not be recovered under SD and MD, but these indicators were completely recovered under MID. The RWC, Chl, Chl-a, Chl-b, Car, and osmotic substances were partially or completely recovered. In conclusion, Artemisia selengensis not only can improve drought resistance by increasing the R/S ratio and osmotic substances but also adopt the compensatory mechanism during rehydration. It is predictable that A. selengensis may benefit from possible future aridification of wetlands and expand population distribution.

“…Flavonoids, carotenoids and polyphenols are the active ingredient contents reported previously for C.officinalis flowers (Bunghez and Ion, 2011;Lim, 2014). The most essence in this plant is formed at full blooming (0.97%) and the least of essence (0.13%) before flowering (Sedghi et al 2011).…”
