“…This arrangement of the chlorenchyma was also confirmed in several Mikania (Rodrigues et al, 1996;Budel et al, 2009;Amorin et al, 2014;Araújo et al, 2015). However, Milan et al (2006) found that the arrangement of the mesophyll of M. glomerata varied in accordance with the different regions of the leaf blade.…”

“…Glandular and non-glandular trichomes are often found in Mikania (Milan et al, 2006;Gasparetto et al, 2010;Appezzato-da-Glória et al, 2012;Amorin et al, 2014;Araújo et al, 2015). In the present study was observed that the set of trichomes can help to differentiate de species.…”

“…However, amphistomatic leaves have also been found (Oliveira et al, 1994;Amorin et al, 2014;Araújo et al, 2015). Anomocytic stomata are common in Mikania (Rodrigues et al, 1996;Oliveira et al, 1999;Budel et al, 2009;Gasparetto et al, 2010;Amorin et al, 2014;Araújo et al, 2015). However, anisocytic (Budel et al, 2009) and (Neves and Sá, 1991) have been described for Mikania species.…”

“…However, anatomical profiles have been used to classify and differentiate species, especially when they are in fragmented or powdery form. The identification of Mikania genus is complex because of its morphological similarities and this has resulted in the indiscriminate use of different plants for the same therapeutic purposes (Amorin et al, 2014;Araújo et al, 2015).…”

Revista Brasileira de Farmacognosia (2016), http://dx. a b s t r a c tMikania belongs to the Asteraceae family and includes a wide range of promising pharmacological activities. Several species of Mikania, which is popularly known in Brazil as "guaco", occur in Southern Brazil and their external morphology is similar. The aim of this study was to investigate the morpho-anatomical characteristics of the leaf and stem of Mikania campanulata, Mikania cordifolia, Mikania glomerata, Mikania hastato-cordata, Mikania microptera and Mikania sessilifolia as a means of providing additional support for differentiating these taxa. The leaves and stems were investigated by employing scanning electron microscopy and light microscopy techniques. The morphological features of Mikania spp. leaves make it possible to differentiate between the species; nevertheless, when the plants were fragmented or pulverized the anatomical features of the leaves and stems supplied additional helpful data in this regard. The main anatomical characteristics were presence of hypodermis and lens shaped epidermal cells, set of trichomes; midrib, petiole and stem shape and vascular pattern; sclerenchymatous ring in the cortex, sclerenchymatous cells and secretory ducts in the pith.

“…Cuticular striae have been found on the leaf surface in various species from the family Asteraceae representing the genera Vernonia, Bidens, and Baccharis [35,36]. A smooth cuticle was reported in Mikania lanuginosa leaves [37], whereas varied cuticular ornamentation (smooth, undulating, wrinkled, or striated) was observed in several species of the genus Cyanus [38]. As a chemically stable epidermal layer, the cuticle serves a very important function in plant water metabolism and constitutes a mechanical protective barrier against abiotic environmental factors, pathogenic microbial penetration, and pest infestation inside the organ [39][40][41][42][43].…”

In Poland Scorzonera hispanica L. is rare in the wild. This species is used as a vegetable and medicinal plant. Currently, attempts are being made to introduce this plant into cultivation in Poland. In this study, comparative analyses were conducted of the epidermis surface micromorphology and anatomical structure of the leaves of S. hispanica 'Maxima' and 'Meres' . The investigations were performed using fluorescence, light and scanning electron microscopy. The cuticle on the surface of epidermal cells is smooth or striated. In the epidermis, there are anomocytic stomata. The stomatal index in the epidermis of the studied cultivars is 9.3-11%. In the midrib of the leaf, there is an aerial cavity which occupies a substantial area. In this place, cracking and breaking of the leaf blade were observed. Over the aerial cavity under the adaxial epidermis, there is a single layer of collenchyma cells and 1-2 rows of parenchyma cells. Tangential collenchyma is also present between the abaxial epidermis and large vascular bundles located in the midrib and on both sides of the large vascular bundles in the lamina. This tissue strengthens the leaf margin. The mesophyll cells located in the abaxial epidermis of the midrib form protrusions surrounding the large vascular bundles. The leaves of S. hispanica represent the equifacial type.

Biomass production, essential oil’s yield and composition of three genotypes of Mikania laevigata Sch. Bip. ex Baker

Mikania laevigata leaves are used worldwide as herbal medicines. Our study investigates the production differences among three different genotypes of this herb: the genotypes' influence on the essential oil yield, chemical composition, and the plant tissues involved in the secretion of the chemical compounds produced by the leaves. The study performed the analysis during the summer and winter seasons. Plants were grown under an organic cultivation system in Oratórios, Minas Gerais, Brazil. Essential oils were extracted by hydrodistillation and analyzed by gas chromatography/mass spectrometer. The analysis highlighted substantial genetic variability among the genotypes. The genotype CENARGEN showed higher biomass production, oil yield, and a high concentration of major constituents detected by chromatographic analysis in essential oils, such as germacrene D and caryophyllene oxide. The season affected the chemical composition of the essential oils. Germacrene D and bicyclogermacrene were the major constituents in the winter-essential-oils; spatulenol and caryophyllene oxide were the major constituents in the summer-essential-oils.
