-(Synopsis of the holoepiphyte and hemiepiphyte Orchidaceae of Floresta Nacional de Caxiuanã, Pará State, Brazil). This study reports the floristic survey of holoepiphyte and hemiepiphyte Orchidaceae in Caxiuanã National Forest, located between municipalities of Melgaço and Portel, near the Marajó area, Pará State, Brazil. Four random excursions for collecting fertile material were taken between April 2009 and November 2010. The family is represented by 33 species and 24 genera in Floresta Nacional de Caxiuanã. The most representative genera were Epidendrum, Scaphyglottis, Catasetum, Encyclia, and Polystachya; other genera were represented by only one species each.

A partir de consultas a herbários nacionais e estrangeiros, cinco espécies e duas variedades de Phymatidium Lindl. foram encontradas no Paraná: Phymatidium aquinoi, P. delicatulum, P. delicatulum var. curvisepalum, P. falcifolium, P. hysteranthum, P. microphyllum e P. microphyllum var. herteri. O gênero é registrado em 35 dos 399 municípios paranaenses, principalmente na Floresta Ombrófila Densa e Floresta Ombrófila Mista, localizadas na Serra do Mar, Primeiro e Segundo Planaltos. Segundo os critérios da IUCN, a maioria dos táxons encontra-se classificada na categoria vulnerável para o estado. Phymatidium delicatulum é a espécie mais comum, com ampla distribuição, e P. hysteranthum a espécie mais restrita, registrada pela primeira vez no estado. Chave de identificação dos táxons, descrições, ilustrações, dados sobre distribuição geográfica e conservação, além de uma lista de materiais representativos, são apresentados. Palavras-chave: biodiversidade, flora do Paraná, Mata Atlântica, IUCN. AbstractBased on the study of material in Brazilian and foreign herbaria, five species and two varieties of Phymatidium are recognized for Paraná state: Phymatidium aquinoi, P. delicatulum, P. delicatulum var. curvisepalum, P. falcifolium, P. hysteranthum, P. microphyllum and P. microphyllum var. herteri. The genus is recorded in 35 of the 399 municipalities of the state, mostly inhabiting Floresta Ombrófila Densa and Floresta Ombrófila Mista vegetation, situated in the Serra do Mar, Primeiro and Segundo Planaltos. Following IUCN criteria, most taxa are classified here as vulnerable in the state. Phymatidium delicatulum is the commonest species, with the widest distribution, and P. hysteranthum, with the narrowest distribution, is recorded for the first time in Paraná. An identification key for species and varieties, descriptions, illustrations, data on distribution and conservation, and a list of representative material are provided herewith.

“…Some species, like A. cathartica, A. schottii and A. blanchettii have being grown as an ornamental plant. 9,10 Among the classes of secondary metabolites isolated from this genus are steroids, terpenoids, flavonoids, coumarins, lignans and iridoids. [11][12][13] Iridoids represent a class of secondary metabolites found in a wide variety of popular medicinal plants.…”

A simple and efficient microwave-assisted extraction process has been developed in order to extract plumieride from Allamanda cathartica flowers. The extracts have been obtained through microwave-assisted extraction (MAE) process with ethanol and ethyl acetate at different time, power and temperatures. Static maceration at room temperature with ethanol and ethyl acetate was obtained in order to compare the efficiency of extraction. HPLC method was validated to quantify plumieride in the extracts. The analyzed parameters: linearity (R 2 = 0.999), precision (CV 3.3%), recovery (98%), specificity (97%), limit of detection (1 µg mL -1), and limit of quantification (2 µg mL -1 ) were satisfactory. The yield of plumieride reached 43% in the extracts under the optimal MAE conditions (10 min, 300W). Plumieride recoveries by conventional extraction method were 12% with ethanol and 22% with ethyl acetate. Time and power parameters on plumieride extraction yield was determined by applying a factorial design and surface plots. Ethanol was the best extractor solvent and it was possible to obtain high contents (52 mg g -1 of dry flowers) at optimized conditions. It can be concluded that MAE process has actual advantages over the conventional extraction method in terms of shorter time and higher efficiency to recover plumieride from A. cathartica flowers.
