“…The alkaloid ancistroheynine A was found in the tip of the shoot and leaf midrib of Liana Ancistrocladus heyneanus and ancistrocladine was found in the branch root of the plant by FT-Raman investigations (Urlaub et al 1997). Many more articles are published describing the localization of different alkaloids with different techniques (Verzár -Petri 1975;Yoder and Mahlberg 1976;Furr and Mahlberg 1981;Neumann et al 1983;Platt and Thomson 1992;Bringmann et al 1996;Mösli Waldhauser and Baumann 1996;Meininger et al 1997;Cai et al 1999;Corsi and Bottega 1999;Bottega et al 2004;Pasqua et al 2004;Alcantara et al 2005;Frosch et al 2006Frosch et al , 2007aNikolakaki and Christodoulakis 2006;Mesjasz -Przybyiowicz et al 2007;Liang et al 2009;Moraes et al 2009;Argyropoulou et al 2010;Christodoulakis et al 2010). …”

“…The presence of peltate and capitate glandular trichomes is a common feature to Lamiaceae species Ascensão et al 1999), and has been reported to species from different genera (Ascensão et al 1995;Corsi & Bottega 1999;Rodrigues et al 2006;Duarte & Lopes 2007;Gonçalves et al 2010). As a rule, peltate trichomes present short stalk and a large secretory head, while in the capitate trichomes the stalk is more than half of the height of the head (Abu-Asab & Cantino 1987;Ascensão & Pais 1998;Werker 2000).…”

“…The morphology of the glandular trichomes is highly variable within the family. In almost all studied species, capitate and peltate trichomes are present (Ascensão & Pais 1998), being common the occurrence of different versions of them (Ascensão et al 1995;Ascensão & Pais 1998;Ascensão et al 1999;Corsi & Bottega 1999;Martins 2002;Maggi et al 2010;Baran et al 2010;Mota et al 2013). Peculiarities on the distribution, arrangement and function of the different glandular morphotypes have been observed in Lamiaceae (Corsi & Bottega 1999) and a correlation between the gland morphology and the composition of secretion has been proposed (Werker 1993;Ascensão & Pais 1998;Corsi & Bottega 1999).…”

Lamiaceae contains many species known for their aromatic properties that are produced by the production of essential oils in glandular trichomes. Hyptis is one of the most common genera of Lamiaceae in the Brazilian fl ora, and includes several species with medicinal value. However, studies on the morphology and functioning of their glandular trichomes are lacking. We analyzed the morphology, histochemistry and ultrastructure of the glandular trichomes in leaves of H. villosa, emphasizing the diff erential distribution of actin fi laments and microtubules in cells secreting hydrophilic and lipophilic compounds. Four morphotypes of glandular trichomes were identifi ed. Total lipid, terpenes, alkaloids, phenolic compounds, proteins and polysaccharides were histochemically detected in all morphotyes. Th is evidences the mixed nature of the secretions of this species, although there are diff erences in the prevalence of lipophilic and hydrophilic components among the glandular morphotypes and among the cells of the same trichome. Th e actin microfi laments are more abundant in cells that secrete mainly hydrophilic compounds, and microtubules predominate in cells that secrete lipophilic compounds. Our results corroborate the correlation between the glandular morphotype and the composition of the secretion produced, with a diff erential distribution of the cytoskeletal elements according to the prevalence of either hydrophilic or lipophilic substances.

“…Klein et al (2004) detectaram, além de carboidratos, a presença de proteínas na secreção dos coléteres de Simira glaziovii (Rubiaceae), as quais possivelmente estão associadas com mecanismo de defesa contra microorganismos. A presença de substâncias lipofílicas na mucilagem é geralmente associada com a proteção contra herbívoros e patógenos além de impermeabilização da superfície de órgãos jovens (Werker & Fahn 1981;Ascensão et al 1995;Corsi & Bottega 1999). Todas as funções acima mencionadas podem ser igualmente atribuídas à secreção produzida pelos coléteres de H. pernambucensis e, embora faltem dados experimentais, a presença dessas estruturas secretoras nos órgãos em desenvolvimento possivelmente conferem proteção contra agentes bióticos e abióticos.…”

ABSTRACT(Mucilage-secreting structures of Hibiscus pernambucensis Arruda (Malvaceae): distribution, morphoanatomical and histochemical characterization). This work studied the mucilage-secreting structures of Hibiscus pernambucensis using light and scanning electron microscopy. Known as guaxima-do-mangue, algodão-do-brejo and embira-do-mangue, this species is a native shrub that occurs in mangrove and restinga along the Brazilian coast, and is important in the production of textile fibers and cellulose, provides abundant mucilage that is used medicinally like other Malvaceae species, and has tannins. The results of this work found colleters, pearl glands, long-stalked secretory trichomes, ducts, cavities and idioblasts. The colleters occur on the shoot apices, stipules, leaf primordia, leaves, young sepals and petals. The pearl glands are present in the adaxial and abaxial surface of the leaf primordia. The ducts and the cavities occur in the vegetative and reproductive shoot apices. The idioblasts occur in the roots, both in primary and secondary stages of development, and in the leaf mesophyll. The secretion of the different secretory structures is made predominantly of acids and neutral polysaccharides, proteins, lipids and phenolic substances. The presence of external and internal mucilage-secreting structures in all plant organs, at different stages of development, represents an important adaptive mechanism to restinga and mangrove environments.
