Bioactive dihydroxyfuranonaphthoquinones from the bark of Tabebuia incana A.H. Gentry (Bignoniaceae) and HPLC analysis of commercial pau d'arco and certified T.incana bark infusions

Tabebuia incana A.H. Gentry (Bignoniaceae) is a tree from the Brazilian Amazon having medicinal uses and is one several Tabebuia spp. known as pau d'arco or palo de arco in this region. Fractionation of the bark ethanolic extract afforded a mixture of 5 and 8-hydroxy-2-(1-hydroxyethyl)naphtho[2,3-b]furan-4,9-diones (1 and 2, respectively) identified on the basis of nuclear magnetic resonance (NMR), infrared (IR) and mass (MS) spectra, whose in vitro antimalarial and antitumor activity have been shown previously. This is the first study on T. incana bark, and 2 are described in this species for the first time. Also, high performance liquid chromatography (HPLC) analysis of T. incana bark tea revealed the presence of the 1 + 2 mixture peak corresponding to a concentration in the range 10-6-10-5 M. The chromatograms of teas prepared from commercial pau d' arco and T. incana bark were also studied and the presence of the 1 + 2 peak has potential for quality control of commercial plant materials.

Estruturas secretoras em cipó-d'alho (Mansoa standleyi (Steyerm.) A. H. Gentry, Bignoniaceae): ocorrência e morfologia

Espécies de Mansoa são denominadas de "cipó-d'alho", por exalarem odor de alho das partes vegetativas e reprodutivas. Contudo, dados sobre morfologia e distribuição das estruturas secretoras presentes em Mansoa são escassos e ausentes para M. standleyi. O presente trabalho objetivou caracterizar a ocorrência e morfologia das estruturas secretoras do eixo vegetativo aéreo de M. standleyi. Para tanto, amostras da lâmina foliolar e de regiões nodais foram fixadas e submetidas às técnicas histológicas e de microscopia eletrônica de varredura. Testes histoquímicos, com os respectivos controles foram aplicados nas estruturas secretoras em fase secretora. Indivíduos de formigas e moscas, que visitavam a espécie foram amostrados, preservados e identificados por entomólogo. As estruturas secretoras do eixo vegetativo aéreo de M. standleyi estão representadas por tricomas glandulares dos tipos pateliformes e peltados. Todos com desenvolvimento assincrônico e presentes nas regiões nodais e lâmina foliolar, principalmente nas partes mais jovens. Nas regiões nodais, os tricomas formam um complexo secretor e, na lâmina foliolar, estão dispersos. As análises histoquímicas revelaram que os tricomas pateliformes são de fato nectários extraflorais e que os tricomas peltados, apresentam uma fração de alcaloides. Os visitantes das glândulas nodais correspondem a formigas Crematogaster (Formicidae) e Ectatomma brunea (Vespoidea, Formicidae) e moscas Oxysarcodexia (Sarcophagidae, subfamília Utitidae (Ulidiidae). Mansoa standleyi possui as estruturas secretoras do eixo vegetativo aéreo semelhantes às citadas pela literatura para Bignoniaceae, sendo esta a primeira vez, que um nectário extrafloral é descrito para a espécie.

Silk and ink. What were silk wallets, and what can they, together with Jacobina Charlotta Munterhjelm’s diary, tell us about the gentry women’s lives in the 18th and 19th century?

The subject of this thesis is the elaborate silk wallets and what can they tell about the gentry women’s lives in the 18th and 19th century Finland together Jacobina Charlotta Munsterhjelm’s diary. Silk wallets were made of silk and decorated by embroidering, they were used to preserve memorabilia and letters. Making these lavish items took time, skills and materials, and the decorations usually contained symbols and messages. As main source there are silk wallets from the collections of the National Museum of Finland and Satakunta Museum, as well as the diary of Jacobina Munsterhjelm from 1799 to 1801. By interpreting these items we can build a picture of gentry women’s lives. The culture of silk wallets is European, the silk wallet phenomenon studied is Swedish-Finnish, and the research is limited mainly in Finland by its sources. This research has been carried out by constructing a cultural context to the silk wallets with the help of Ginzburg’s methods from his work Juusto ja madot - 1500-luvun myllärin maailmankuva. Silk wallets represent the gentry as well as the communication culture in the 18th and 19th centuries, but have remained unstudied. The thesis consists of two parts, the first focuses on the silk wallets, from where were they developed, how they were made, and to their decorations. The silk wallet culture developed among the gentry handicrafts during the 18th century and faded during the early 20th century. The making of the silk wallets demanded time, skills and materials. The decorations contain messages and symbols – they contain the possible affections the makers might have toward the receiver, and reflect the status and qualities of the receiver. The second part examines the makers, the gentry women, and the handicraft culture which played a big role in their lives, through silk wallets and the diary of Jacobina Munstehjelm. From there it continues to the affections and meanings which can be found from the silk wallets.
