“…Toxicity -Toxicity of Neotropical Anacardiaceae has been widely investigated (see review in Aguilar-Ortigoza and Sosa 2004b), and 10 genera cause dermatitis, with five additional genera having anecdotal evidence of causing dermatitis (Actinocheita, Campnosperma, Loxopterygium, Mosquitoxylum, and Spondias). Genera that are confirmed to cause dermatitis and for which associated phytochemicals have been isolated include Anacardium (Sampietro et al 2013), Astronium (Vilar et al 2004, Comocladia (Potthoff and Brockmeyer 2009), Lithrea (Alé et al 1997), Mauria (Hurtado et al 1982), Metopium (Rivero-Cruz et al 1997, Pseudosmodingium (Aguilar-Ortigoza and Sosa 2004a), Schinopsis (Sampietro et al 2017), Schinus (Morton 1978), and Toxicodendron (Moreno 2008) and have been included in many survey papers (Gross et al 1975;Lampe 1986;Hurtado 1986;Mitchell 1990;Aguilar-Ortigoza et al 2003). For most of these genera, the offending compounds are urushiols, which are oily mixtures of alkyl catechols (primarily pentadecyl-and heptadecyl-catechols).…”

Anacardiaceae is an ecologically and economically important plant family of about 200 species in 32 genera in the Neotropics. The family is particularly diverse in leaf architecture and fruit morphology, making it a model family to study the evolution of structural diversity as it correlates with lineage diversification. This fruit diversity is the primary reason 11 of the Neotropical genera are monotypic and that so many genera are recognized in the Anacardiaceae. The economic value of the family is driven by the global markets for cashews, mangoes, and pistachios, but there is great potential value in its medicinal properties. At least 10 Neotropical genera cause contact dermatitis, which is a rich area for research in the family. Here presented is a review of the systematics and structural diversity of the family. Particular attention is given to the morphology, economic botany, paleobotany, ecology, and taxonomy of native and naturalized genera. Keys to Neotropical Anacardiaceae subfamilies and genera are provided along with descriptions of native genera.

“…Histochemical studies performed in the Rhoeae tribe suggest interspecific variations in the distribution of secondary metabolites within the tissues. For instance, Schinopsis balansae and S. lorentzii accumulated flavonoids only in the mesophyll cells [10] whereas Spondias tuberosa, S. mombin and Schinus terebinthifolius also exhibited accumulation in the epidermal and parenchyma cells near the midvein [11]. Hence, the aim of this work was to compare the leaf architecture and in situ localization of flavonoids, terpenes and other secondary metabolites in both Schinus species.…”

Schinus fasciculatus (Griseb.) I.M. Johnst and S. gracilipes I.M. Johnst are plants rich in secondary metabolites traditionally used for dye, fodder, and medicinal purposes. This work is a comprehensive comparative analysis of leaf architecture and histochemistry between the two species to determine the in situ localization of their secondary metabolites. Leaf anatomy was characterized by classical histological methods. Fresh leaf cross-sections were treated with ferric chloride, Fast Blue B, aluminium chloride, vanillin-HCl, 1% KOH, Sudan IV, Neu´s, NADI, Liebermann-Burchard, PAS, and lugol. The leaves of both species shared morphological traits suitable for survival in water-limited environments, such as amphistomacy and anomocytic stomata. Glandular and non-glandular trichomes were abundant in S. gracilipes suggesting that they have a protective role against biotic and abiotic stresses. Some features like mesophyll structure and thickness indicate S. fasciculatus leaves respond better to the selective pressure of extreme environments. HIGHLIGHTS• Secondary metabolites were localized in leaves of Schinus shrubs.• Terpenoids and phenolic compounds were widely distributed in the leaves.• Phloem ducts contained lipids and alkaloids.• Glandular trichomes produce phenolics, terpenes and polysaccharides• Ecophysiological roles are inferred from distribution of the secondary metabolites

The article deals with the method of diaphonization, which consists in clarification and staining of tissues, organs and whole organisms for long-term storage in the form of preparations as one of the modern methods of morphological research and, in general, a powerful tool for studying the internal structure and topography of organisms. The authors have analyzed the history of the diaphonization method, its advantages and disadvantages. Its advantages include the ability to study the internal anatomy without destroying the object, detailing structures, preserving samples for further research, and the possibility of combining with other modern research methods. Despite its advantages, the diaphonization method also has certain limitations and disadvantages (possible deformation of structures, loss of color, time and space complexity, and limitations in application to certain types of organisms). With its three main application vectors (clinical, experimental, and botanical), the diaphonization method is an essential tool for researchers in many fields, which continues to evolve and find new applications, improving the overall scientific picture of understanding the structure of organisms and contributing to scientific progress. The article also highlights the importance and prospects of combining the diaphonization method with other techniques to determine a more accurate picture of the relative location and structural features of certain tissues, organs, and systems.
