Phytochemical investigation into the CHCl extract of the fruits of Barringtonia racemosa resulted in the isolation of two new metabolites along with isoracemosol A and betulinic acid as known metabolites. The new compounds were characterised as phytosphingosine-type ceramide [(2S,3S,4R)-2-[(2R)-2-hydroxyhexadecanoyl amino]-hexacos-8(E)-ene-1,3,4-triol, 1] and racemosol E [21β-acetoxy-22α-(2-methylbutyroxy)-olean-12-ene-3β,16α,28-triol, 2] on the basis of extensive spectroscopic data analysis and chemical modifications. In addition, the self-gelating property of isoracemosol A (3) was investigated for the first time, which leads to the unexpected agglomerated porous-like morphology.

To elucidate the mechanisms governing the salt tolerance of the endangered semi-mangrove plant , the biomass, photosynthetic and fluorescent characteristics, and anatomical structure of were studied under low, medium and high salt stress. The results showed that the stem dry weight, net photosynthetic rate, intercellular CO concentration, Fv/Fm, and ΦPSI of decreased under high salt stress, which led to a significant reduction in total dry weight. Stem dry weight was significantly positively correlated with the thickness of palisade tissue and significantly negatively correlated with the thickness of the epidermis of roots and xylem of stems.

Mangrove species are broadly classified as true mangroves and mangrove associates. The latter are amphibious plants that can survive in the intertidal zone and reproduce naturally in terrestrial environments. Their widespread distribution and extensive adaptability make them ideal research materials for exploring adaptive evolution.

Mangrove plants play an important role in the remediation of heavy-metal-contaminated estuarine and coastal areas; is a typical semi-mangrove plant. However, the effect of heavy metal stress on this plant has not been explored. In this study, tolerance characteristics and the accumulation profile of cadmium (Cd) and lead (Pb) in were evaluated.

With global climate change and increased industrialization, drought and heavy metals have become common abiotic stress factors for coastal vegetation. In this study, we investigated the ecophysiological responses of the seedlings of three subtropical coastal tree species (Barringtonia racemosa, Hibiscus tiliaceus, and Terminalia neotaliala) to drought stress (D), cadmium addition (Cd), and their combined effects (Cd + D). The results showed that, for all three plant species, treatment D significantly decreased A, Y(II), qP, and ETR; increased the concentrations of PRO, soluble sugars, ABA, MDA, and O; and increased the activity of Rubisco.
