This study evaluated the anatomical and chemical components of the bark of Protium tenuifolium, a tree species from the Brazilian Amazon, to provide information supporting its value in various industries as a source of polyphenols and natural antioxidants. The bark anatomy was analysed, as was the overall chemical composition (extractives, lignin, suberin, ash and polysaccharides), and a quantitative elemental analysis was performed of the bark and two tannin extracts (extracted with water only and with a mixture of water and Na2SO3). The phenolic composition and antioxidant activity of the bark extracts were quantified. The results indicated that the bark is composed of conductive phloem, nonconductive phloem and rhytidome. The average chemical composition was 15.9% extractives, 35.3% total lignin, 1.9% suberin, 15.4% ash and 31.5% polysaccharides. The condensed tannin yield in the extract obtained with water alone was 5.1%, and that in the treatment with water and Na2SO3 was 8.1%. The ethanol-water extract had a high phenolic content (112.6 mg GAE g-1 extract). The bark extract showed strong antioxidant activity, reaching 83.5% inhibition of DPPH free radicals, which was higher than the value of 75.0% for the commercial antioxidant BHT at the same concentration. These results demonstrate that Protium tenuifolium is a potential natural Amazonian source of phenolic compounds and antioxidants and can be used for medicinal purposes and the production of various sustainable products, such as cosmetics. The extraction of these compounds adds substantial value to the bark of this Amazonian species.

“…31 In relation to the concentration of condensed tannins, S. adstringens also presented higher values (558.1 mg CE g −1 of bark extract) than those reported for M. urundeuva (8.5 mg CE g −1 of extract). 31 The phenolic compound yield of the dry bark extract was 81.0%. The amount of dry extract that was added to the solutions was corrected to obtain 100% polyphenols.…”

“…The extract from S. adstringens presented a high content of polyphenols, flavonoids, and condensed tannins. Compared with Myracrodruon urundeuva species, S. adstringens had a high concentration of flavonoids (232.1 mg CE g –1 of extract), while that of Myracrodruon urundeuva presented a lower value (91.36 mg CE g –1 of extract) . In relation to the concentration of condensed tannins, S. adstringens also presented higher values (558.1 mg CE g –1 of bark extract) than those reported for M. urundeuva (8.5 mg CE g –1 of extract) .…”

Urease (EC 3.5.1.5) activity is one of the processes that most contributes to urea loss by ammonia volatilization in agriculture. The present study describes the capacity of polyphenols extracted from barbatimão tree bark (Stryphnodendron adstringens (Mart.) Coville) on inhibiting the urease enzyme extracted from Canavalia ensiformis (L.) DC. Fourier transform infrared spectroscopy (FTIR) coupled to an attenuated total reflection (ATR) accessory was chosen to determine the enzymatic kinetics. This spectroscopic technique is used to perform more sustainable enzyme kinetic studies due to the decreased use of chemicals, including highly toxic reagents. The inhibition capacity of the polyphenols was compared with N-(n-butyl)thiophosphoric triamide (NBPT). The reactions occurred in 20 mM potassium phosphate buffer, pH 7.2, and the crude urease extract was used. The maximum intensity of asymmetric stretching of the bicarbonate functional group at 1361 cm–1 was measured to study the kinetics of urease. The kinetic constants V max and K m were determined by nonlinear fitting with the Michaelis–Menten model. The data obtained showed the strong potential of polyphenols from bark to be used as urease inhibitors on fertilizers in soil, decreasing the use of chemical reagents exogenous to the environment, such as NBPT.

“…The tissues of the floral parts of both floral morphs showed similar anatomical features: striated cuticle, epidermis with tector trichomes at the margins, and idioblasts in the mesophyll (Figure 2 E, F, and G). In male and female flowers, numerous secretory ducts and idioblasts were present mainly in the region of the nectariferous disk (Figure 2 H, J, and K) since idioblasts and secretory ducts are characteristic of the family Anacardiaceae, to which aroeira belongs (Sousa et al, 2022). Furthermore, in species of the genus Astronium, schizolysigenous ducts are associated with the phloem, extending to the dead phloem in the outer bark and to leaves, as observed by Sousa et al (2022) and Nascimento- Silva et al (2011), respectively, as well as to flowers, as reported, for the first time in the present study, in inflorescences of the aroeira tree.…”

“…To date, the histochemical studies of the vegetative parts of the aroeira tree have focused on: leaves, showing the presence of starch granules, calcium oxalate crystals, fatty compounds, resins, phenols, and alkaloids in the tissue (Nascimento-Silva et al, 2011); and bark, characterized by the presence of secretory ducts and dead phloem between periderms, with large amounts of phenols in all tissues (Sousa et al, 2022). However, there are no known works about the presence and location of these substances in the floral tissues of aroeira, particularly in the nectary, where honeybees collect nectar to produce honey.…”

The objective of this work was to quantify the content of total phenolic compounds in monofloral honey from aroeira (Astronium urundeuva) trees and to verify, through histochemical tests, if these compounds are present in the floral tissues. The apiary, with Apis mellifera bees, was installed among aroeira trees in the semiarid region of the state of Minas Gerais, Brazil. From the anatomy of the flowers and of the inflorescence rachis, an ornamented epidermis, tector and glandular trichomes, idioblasts, and a developed secretory system were observed. Aroeira honey has an average phenolic content of 142.5±22.6 mg 100 g-1, a value considered very high when compared with those of other monofloral honeys from Brazil and around the world. Histochemical tests detected the presence of phenolic substances in the idioblasts and secretory ducts associated with the phloem in the floral tissues, especially in the nectar parenchyma, epidermis, and glandular trichomes. Phenolic compounds are present in the floral tissue of both floral morphs, mainly in the nectary where honeybees collect nectar. The obtained results are the first, in the literature, indicative that the phenolic compounds produced by aroeira trees are transferred through the nectar to the honey. This study contributes to the establishment of quality standards for monofloral aroeira honey and to the identification of its botanical origin.
