Introduction: Elsholtzia species are very popular in Chinese, Tibetan and Vietnamese folk medicine to treat several diseases. Despite the wide range of biological activity and the study of the chemical composition of individual species, the microscopic characteristics of plants of this genus are insufficiently studied. In the article the anatomical structure of two species Elsholtzia Willd. of flora of Ukraine is represented. The sources of literature provide only a morphological description of Elsholtzia stauntonii and Elsholtzia ciliate. We analyzed crosssections and ultrastructure of leaf blade, petiole, petal and stem, determined their anatomical features, and investigated the ultrastructure of seeds. We have compared the obtained data between this two species of this genus that grow on the territory of Ukraine under similar conditions. Methods: Microscopic analysis was carried out by the well-known methods using the microscope XSP-146TR and ImageJ program. Anatomical structure of Elsholtzia stauntonii Benth. and Elsholtzia ciliate Thun. are studied and main diagnostic features are highlighted. The ultrastructure of the surface of the epidermal tissue of leaves, stems and seeds were studied additionally, using scanning microscopy methods. Results: The diagnostic microscopic distinguishing features of E. ciliate raw material from E. stauntonii are: the presence of small glandular triсhomes, singly placed on the veins and the presence of long non glandular triсhomes on the central vein of abaxial side. Non glandular triсhomes of E. ciliate are three times longer compared to another investigated species. The presence of numerous triсhomes and massive clusters of stem sclerenchyma E. stauntonii can be considered additional taxonomic criteria for comparing the studied species. Conclusion: The practical significance of our research will use to develop of quality control methods for medicinal herbal raw material {\textendash} {\guillemotleft}Herba Elsholtziae Stauntonii{\guillemotright}, {\guillemotleft}Herba Elsholtziae ciliate{\guillemotright}.

Objective: To analyze the accumulation of potential photo-protective compound groups, include phenol, flavonoid, and tannin in the leaf tissues of Sonneratia caseolaris (L.) Engler. Methods: The research used Sonneratia caseolaris (L.) Engler leaves as materials. The total of compound groups and photo-protective ability level of each tissue was measured using spectrophotometry, while detection of compound group accumulations in the leaf tissue were observed using histochemical assay. Results: Epidermis extract contained the highest content of total phenolic compounds (phenol, flavonoid, and tannin), followed by those of mesophyll and whole leaf. Moreover, Sun Protection Factor (SPF) value of epidermis was also higher than those of mesophyll and whole leaf, considering that there were no significant difference of SPF value between mesophyll and whole leaf. Result of histochemical assay of S. caseolaris fresh leaf sections showed that phenol, flavonoid, and tannin were highly accumulated in the epidermis and some parts of mesophyll. Conclusion: Potential photo-protective compound groups of S. caseolaris leaves were accumulated in epidermis and mesophyll. However, epidermis showed the highest level of potential photo-protective compound groups than those of other tissues. Photo-protective ability of epidermis also showed higher value than those of mesophyll.

Background: Spondias mombin L. is fruit specie found in Tropical America and the coast of Africa, popularly known as cajazeira. Several researches with extract of leaflets show a diversity of promising pharmacological activities such as antibacterial activity, antiviral against dengue virus type 2, anti diabetic, among others. Objective: This paper aims to study the anatomical characteristics, phytochemical and histochemical from leaves of this species. Materials and Methods: Cross and paradermic sections from leaves were submitted to double staining with astra blue and safranin process for the anatomical study. Anatomical analysis of the structures was performed using an optical microscope. For ultra structure analysis, the leaf fragments, after processing and gold coating, were observed under scanning electron microscopy (SEM). The phytochemical analyses were performed using thin layer chromatography and the histochemical analyses using specific reagents for each metabolite group. Results: The leaf has anomocytic and tetracytic stomata distributed on abaxial surface. The midrib has convex symmetry with collateral vascular bundles in a closed arc disposition. The phytochemical showed the presence of mono and sesquiterpenes, triterpenes and steroids, hydrolysable tannins, phenylpropanoid glycosides, cinnamic derivatives and flavonoids. The histochemical tests allow us to state that phenolic compounds are found in the palisade parenchyma cells. Lignins can be found in woody vascular bundles and in perivascular sclerenchyma fibres. The volatile oils were evidenced in the schizogenous cavity, present in the parenchyma of the midrib. Conclusion: The results allowed characterizing anatomically the leaves of this species, outlining a profile of its phytochemical constituents and, in addition, determining which anatomical structures of storage of these metabolites by the plant.
