Background: The leaves of many species of Maytenus are used to prepare herbal drugs to treat stomach ulcers. Questions: In order to define key anatomical characters for the unambiguous species identification, the present study aimed to describe the leaf morphoanatomy of M. imbricata. Species study: Maytenus imbricata Mart. ex Reissek (Celastraceae) Study site and dates: Collected in an area of 'campo rupestre' -one of the Brazilian Savannah vegetation (20º 22' 11.02" S, 43º 30' 22.81" W) in August 2015. Methods: The plant material was processed according to commonly used techniques in plant anatomy studies. Results: The major anatomical characters for several species of Maytenus identification also present in M. imbricata are marginal teeth, conspicuous epicuticular wax, ciclocytic stomata, thick external periclinal wall with large pits on epidermal cells and vascular system with a closed loop shape in cross-section. Strips on the anticlinal walls on epidermal cells and conspicuous gelatinous fibers sheath are diagnostic for M. imbricata. Conclusions: Strips on the anticlinal wall of the epidermal cell are reported for the first time for the genus. The xeromorphic traits help the species to survive in arid environments and may contribute to quality control of the raw material used in the production of herbal medicines. Keywords: cell wall strips, colleter, gelatinous fiber, xeromorphic. ResumenAntecedentes: Las hojas de muchas especies de Maytenus se utilizan para la preparación de medicamentos para el tratamiento de las úlceras de estómago. Preguntas: Con la finalidad de contribuir a la identificación de la especie, este estudio tuvo como objetivo describir la morfología y anatomia de la hoja de M. imbricata. Especie de estudio: Maytenus imbricata Mart. ex Reissek (Celastraceae) Sitio y años de estudio: Recolecta de material en una zona de 'campo rupestre' -vegetación del cerrado brasileño (20º 22' 11.02" S, 43º 30' 22.81" W) en agosto del 2015. Métodos: El material vegetal se procesó mediante las técnicas que se utilizan en los estudios de anatomía vegetal. Resultados: Los principales caracteres anatómicos para la identificación de varias especies de Maytenus, que están presentes en M. imbricata, son los dientes marginales, la cera epicuticular gruesa, los estomas ciclocíticos, las células epidérmicas con la pared periclinal externa gruesa, con grandes punteaduras y la sección transversal del sistema vascular en un círculo cerrado. Las estrías en las paredes anticlinales y las fibras gelatinosas son caracteres diagnósticos para M. imbricata. Conclusiones: Las estrías que se forman en la pared de las células epidérmicas se reportan por primera vez en el género. Estos caracteres xeromórficos ayudan a la especie a sobrevivir en ambientes áridos y pueden contribuir al control de la calidad de la materia prima utilizada en la producción de medicamentos. Palabras clave: caracteres xeromórficos, coléteres, estrías en la pared celular, fibras gelatinosas.

Processing of plant material The present study focused on the stem and bark of G. tiliifolia owing to its use as a source of herbal shampoo. The stem and bark of G. tiliifolia was washed well in running tap water followed by rinsing in ABSTRACT Introduction: Grewia tiliifolia Vahl. is an important ethnomedicinal tree widely distributed in the tropical and subtropical areas and has been used as a source of herbal shampoo by the local communities in many places of Kerala, India. It has been routinely used in the traditional Ayurvedic medicines against cough, ulcers, cancer, skin diseases, pruritus, wounds and urinary infections. Objective: The aim of this study was the pharmacognostical standardisation of G. tiliifolia. Methods: Pharmacognostic evaluation of G.tiliifolia bark was carried out by usual macroscopic and microscopic examinations and phytochemical screening. In addition, the quantification of major phytoconstituents such as alkaloids, flavonoids, phenols, tannins, saponins and carotenoids were carried out by standard procedures which can further throw light on the medicinal use of this ethnobotanically important plant. Results: Anatomical studies revealed the presence of prismatic crystals of calcium oxalate and druses in the stem and bark. Mucilage cavities were observed only in the stem. Histochemical studies revealed that the tissues of phloem parenchyma are the main localising region of various phytoconstituents. The physicochemical examinations along with the estimation of alkaloids, flavonoids, phenols, tannins, saponins and carotenoids will help in setting the pharmacopoeial standards of G.tiliifolia. Conclusion: The present study provides useful information that will help in the exact identification as well as assessment of purity of crude drugs of G.tiliifoia.

Mauritia flexuosa and Mauritiella armata belong to the family Arecaceae and are widely found in Brazil. Aim: In this work were evaluated: the phytochemical profile of the secretion popularly known as M. flexuosa wine, antioxidant activity of leaf, root and petiole hydroethanolic extracts of the two species, as well as the quantification of flavonoids and the chromatographic profile by means of High Performance Liquid Chromatography. Materials and Methods: The chromatographic profile was determined by high performance liquid chromatography, quantification of flavonoids and antioxidant activity, were performed by spectrophotometric method. Results: Antioxidant activity and presence of flavonoids were observed in the extracts of all the analyzed structures of the two species. The phytochemical profile of the wine evidenced the presence of secondary metabolites reported in other structures of M. flexuosa. In the chromatographic analysis, it was observed that the extracts evaluated have between three and nine compounds. Conclusion: Further studies should be performed to identify the active compounds in the two species. Key Messages: In this work were evaluated: the phytochemical profile of the secretion popularly known as M. flexuosa wine, antioxidant activity of leaf, root and petiole hydroethanolic extracts of the two species Mauritia flexuosa and Mauritiella armata (Arecaceae), as well as the quantification of flavonoids and the chromatographic profile. GRAPHICAL ABSTRACT SUMMARY• The current work were evaluated: the phytochemical profile of the M. flexuosa wine, antioxidant activity of leaf, root and petiole hydroethanolic extracts of the two species, as well as the quantification of flavonoids and the chromatographic profile by means of high performance liquid chromatography. • Researchers have been stated the presence of flavonoids and antioxidant activity of were observed in the extracts of all the analyzed structures of the two species. • Researchers have been stated the presence of phytoconstituents in wine. • In the chromatographic analysis, it was observed that the extracts evaluated have between three and nine compounds.
