“…Essential oils from Lampranthus multiradiatus (Mesembryanthemum edule) leaves have been used by traditional healers in South Africa for the treatment of respiratory tract infections, tuberculosis, dysentery, diabetic mellitus, laryngitis, and vaginal infections [36]. Several studies have shown that plants from this genus have antifungal, antiyeast, and antibacterial activity [36][37][38]. It has also been reported that other Lampranthus species such as Lampranthus sociorum are sources of pigments that have been shown to have activity against oral microbial organisms such as Streptococcus and Candida [39].…”

Fungal infections have been rising due to the increasing number of immunocompromised patients and intensive use of some antifungal agents. Lampranthus francisci is an ornamental succulent plant. In Zimbabwe, the fresh sap from the leaves is used to treat fungal scalp infections. The activity of L. francisci fresh and dry acetone, ethanol, hydroethanolic, and aqueous extracts against Candida albicans and Candida krusei was determined. Mouse peritoneal cavity cells and sheep red blood cells were used to investigate L. francisci’s toxicity profile. The hydroethanolic extracts were the most effective extracts against C. albicans. The fresh ethanol extract was the most effective extract against C. krusei. The dry acetone extract, dry ethanol extract, and the fresh and dry aqueous extracts promoted the growth of C. krusei. The hydroethanolic extracts caused haemolysis of sheep cells. The hydroethanolic extracts promoted the growth of the mouse peritoneal cavity red blood cells. Both aqueous extracts increased the density of the mouse cells, but only the fresh extract increased the metabolism of the mouse cells. L. francisci has some fungicidal activity and boosts the growth of immune cells, thus validating its use in ethnomedicine. L. francisci extracts are potential leads for the isolation of immune stimulatory compounds.

Iron (Fe) deficiency is one of the major environmental stresses affecting plant production in the world. The selection of tolerant genotypes is considered an effective remediation strategy for this stress. The present study was carried out in order to investigate the biodiversity within Medicago truncatula plants in response to Fe deficiency, to identify tolerant genotypes and to assess the main tolerance mechanisms. To do this, a screening test was performed on 20 M. truncatula genotypes cultivated in minimal medium. Biometric and physiological markers were analyzed, including plant biomass, chlorophyll and root architecture. Results showed a biodiversity among the 20 genotypes. Interestingly, Fe deficiency tolerance was highest in TN8.20 and A17 genotypes. However, the lowest tolerance behavior was observed in TN1.11 and TN6.18. In order to investigate the main tolerance mechanisms, an experiment was conducted in the hydroponic system on already selected genotypes. Assessment of Fe deficiency tolerance was performed mainly on plant growth parameters, Fe (III)‐chelate‐reductase activity, rhizosphere acidification and antioxidant system defense. The relative better tolerance of A17 and TN8.20 to Fe deficiency was positively correlated with their capacity to maintain higher Fe‐acquisition efficiency in roots via rhizosphere acidification and the stimulation of Fe (III)‐chelate‐reductase activity. Moreover, tolerant genotypes showed the lowest decreases in chlorophyll content and photosynthetic activity (CO2 assimilation) compared to the sensitive ones. The efficiency of antioxidant capacity of the tolerant genotypes was revealed in stimulation of catalase (CAT) and peroxidase (POX) activities as well as accumulation of polyphenols, leading to the maintenance of cell integrity under Fe deficiency.

“…F. thymifolia was shown to contain high amount of phenolic acids (caffeic, chlorogenic, sinapic and gallic acids). These compounds and specially caffeic and chlorogenic acids were found to possess the strongest antiviral activity (Karar et al 2016 (Falleh et al 2013). Indeed, chromatogram profile of two species belongs to the Frankinaceae family revealed the presence of number of no identified compounds.…”
