“…The interest in evaluating various mangrove fruits for their nutritional value is growing well [2]. Several studies on non-mangrove fruits' nutritional values and it micronutrients have already been carried out [3]. Still, fewer studies have been documented for mangrove fruits.…”

Mangrove plants are popularized for their edible and vital source of food. Mangroves in Pulau Sembilan, Langkat, North Sumatra, Indonesia were supported by the high plant diversity. These major tree species were provided in mangrove fruits annually and assist in finding a new variety of functional food materials. Bioprospecting was denoted the exploration of bioresources material to useful derived mangrove products. The present study aims to assess bioprospecting based-nutritional parameters, antioxidant content, and elemental analysis (micronutrient and macronutrient) in fruits of eight mangrove plants: Avicennia officinalis, Bruguiera cylindrica, Rhizophora apiculata, Ceriops tagal, R. stylosa, R. mucronata, Xylocarpus granatum and Sonneratia alba in Pulau Sembilan, North Sumatra, Indonesia. Out of seven nutritional parameters, A. officinalis recorded the highest in three parameters (protein, total sugar, and non-reducting sugar), X. granatum recorded highest in two parameters (fat and moisture content), among all studied species followed by R. mucronata, and R. stylosa in one parameter (ash and reducing sugar), respectively. Among the antioxidant content, R. mucronata exhibited the highest ascorbic acid content and phenolic acid. Beta carotenoid was maximum in C. tagal. The highest macro element varied among the mangrove fruits: sodium was recorded in R. apiculata, potassium content was noted in X. granatum, and calcium was in S. alba. Likewise, the highest microelement was spread among the mangrove fruits: X. granatum (iron), R. mucronata (manganese), A. officinalis (cupper), and S. alba (zinc). Thus, this study's findings showed the mangrove fruits have reported prospective values as antioxidants, bio-nutrition, and renewable food sources potential for the adjacent mangrove.

“…Cuticular waxes are secreted by cells of the epidermis and deposited on all aerial plant organs, protecting them from environmental stresses 33 and reducing excessive leaf water loss (residual transpiration) 34 . The presence of n -alkanes and triterpenes, as the main constituents of epicuticular wax, is recurrent among restinga and mangrove plants that use residual transpiration as a mechanism of tolerance under saline stress 3 , 34 , 35 . Pentacyclic triterpenoids, such as β-amyrin and lupeol, which are representative of the oleanane and lupane groups, are widely distributed in mangrove plants and is associated with features tolerant to salt.…”

“…Brazil has one of the largest areas of mangroves, stretching about 14,000 Km 2 along its coast. Sepetiba Bay, located in Rio de Janeiro, is an aquatic saline environment surrounded by a large restinga (coastal tropical and subtropical moist broadleaf forest in eastern Brazil) and mangrove 3 . These ecosystems have been severely impacted by anthropogenic activities since the 1970s.…”

“…Leaf assessment in different ecosystems allows researchers to detect pollutants that may cause changes in plant morphoanatomy, physiology and metabolism. Different studies of mangroves have shown the presence of metals, metalloids and plasticizers in leaves 1 , 3 , 7 , 8 . These substances are taken up by plants through their stomata, lenticels or epicuticular waxes in leaves, but roots are the first and most common organs in contact with pollutants.…”

Brazilian mangroves have been severely impacted by metallurgical, petrochemical, pyrometallurgical smelters and other industrial activities. In Rio de Janeiro, mangroves are part of the Atlantic Rainforest now under the stress of high levels of industrial waste. Therefore, this work aimed to detect potentially toxic elements (PTEs) by evaluating the leaves of Laguncularia racemosa (L.) Gaertn. f. collected from three mangroves with different levels of pollution. To gain further insight toward an accurate diagnosis of the effects of anthropogenic pollution on mangrove stands, we evaluated leaf epicuticular wax composition, as well as morphological and anatomical traits. Samples were analyzed using inductively coupled plasma-optical emission spectroscopy (ICP-OES), gas chromatography (GC) and microscopy. Results revealed variation in the contents of PTEs among the three mangroves from lowest to highest concentration, as follows: Al (0.30–0.73), Pb (0.095–0.325) and Zn (0.25–0.30) mg/kg. Zn was detected in sclerenchyma tissues. Leaf epicuticular wax contained more than 50% of triterpenes, in particular, the pentacyclic triterpenes lupeol (41.61–55.63%) and β-amyrin (8.81–16.35%). Such high concentrations promote the increase in leaf permeability to salts and PTEs. Micromorphology of leaf epicuticular wax in L. racemosa also varied among the three evaluated sites, especially around stomatal openings, but no harmful changes were noted. L. racemosa plays a key role in the rich diversity of mangrove ecosystems. As such, this species could, by the presence of PTEs in its leaves, be a suitable biomonitor of toxic substances in coastal environments of the world and used accordingly in strategies designed for eco-sustainable technologies.

“…Pentacyclic triterpenoids, such asamyrin and lupeol, which are representative of the oleanane and lupane groups, are widely distributed in mangrove plants associated with features tolerant to salt(Basyuni et al 2012). Pentacyclic triterpenes were identi ed as the main components of A. shaueriana epicuticular wax(Victório et al 2020), as well as the main components of L. racemosa leaves in this study. However, our results are different from those of Ra i et al(1996) who veri ed only trace amounts of triterpenes in leaf wax of L. racemosa from Guyana (western Atlantic coast) and 8.5% in wax extract in a population from Gabon (eastern Atlantic coast) that did not present lupeol.The presence of hydrocarbons in leaf epicuticular wax has proven valuable in chemotaxonomic studies of different botanic families.…”

Leaves of Laguncularia racemosa (L.) Gaertn. f. were collected from the following mangroves along Brazil’s southeastern Atlantic coast: Coroa Grande (CG), Pedra de Guaratiba (PG) and Marambaia (M). This work aimed to evaluate the presence of minerals by Energy Dispersive X-Ray Spectroscopy (EDS) and Inductively coupled plasma - optical emission spectrometry (ICP-OES); the chemical composition of epicuticular waxes by gas chromatography–mass spectrometry (GC-MS) and the leaf morphoanatomical features. Results revealed variation in metal contents among mangroves in the following ranges: Al (0.307–0.73), Cd (0.004–0.016) and Pb (0.095–0.325) mg/mL by ICP-OES. Leaf epicuticular wax contained more than 50% of triterpenes, in particular the pentacyclic triterpenes lupeol (41.61–55.63%) and β-amyrin (8.81–16.35%), as well as n-alkanes, such as hentriacontane and tetratetracontane. In particular, we observed differences in the micromorphology of the epicuticular wax in the leaves of plants from each of the three evaluated sites, especially around stomatal entrances. Histochemical reaction indicated the presence of zinc in fiber cell walls and druse crystals of leaves.
