“…Freitas et al (2002) isolaram e identificaram do caule subterrâneo de S. odoratissima, a 8-prenil-7-geraniloxicumarina, a cumarina aurapteno e o alcaloide esquimianina. Ribeiro et al (2005) isolaram das raízes de Spiranthera odoratissima, além da limonina, dois novos limonoides, três alcaloides furoquinolínicos (dictamina, γ-fagarina e esquimianina), três alcaloides β-indoloquinazolínicos (rutaecarpina, evodiamina e 1-hidroxirutaecarpina), a cumarina aurapteno e o β-sitosterol.…”

RESUMO:A Spiranthera odoratissima A. St.-Hil. (manacá) é um arbusto cujas raízes são utilizadas popularmente contra dores musculares, de estômago e de cabeça, disfunções hepáticas, reumatismo, e como estimulante do apetite. As folhas são empregadas como depurativo do sangue, nas afecções renais e hepáticas. O objetivo deste trabalho foi realizar o estudo morfo-anatômico de S. odoratissima, bem como a triagem fitoquímica, a determinação dos teores de água, cinzas totais e insolúveis em ácido. O material vegetal foi coletado em Leopoldo de Bulhões/ Goiás e os estudos morfo-anatômicos e a triagem fitoquímica foram realizados utilizando as técnicas convencionais. Verificou-se que a folha é hipoestomática, com estômatos anomocíticos e a epiderme apresenta papilas na face abaxial. O mesofilo é dorsiventral e a nervura principal possui drusas de oxalato de cálcio e cavidades secretoras. O pecíolo apresenta sistema vascular em forma circular. Na raiz, em crescimento primário, observou-se cilindro vascular com organização diarca. Na prospecção fitoquímica detectaram-se fenóis, taninos, cumarinas, flavonoides, triterpernos/esteróis, antraquinonas e antocianinas nas folhas e alcaloides, cumarinas, amido e saponinas nas raízes. Esses resultados são parâmetros importantes para o controle de qualidade dessa matéria-prima vegetal.Palavras chaves: Cerrado, controle de qualidade, plantas medicinais, Rutaceae.ABSTRACT: Pharmacognostic study of the leaves and roots of Spiranthera odoratissima A. St.-Hil. (Rutaceae). Spiranthera odoratissima A. St.-Hil. (manacá) is a shrub whose roots are popularly used against stomach pains, headache, muscle pain, liver disorders, rheumatism and as an appetite stimulant. The leaves are used as a blood depurative and for liver and kidney disease. The purpose of this work was to perform the morphological and anatomical study, the phytochemical screening and determine the water content and the levels of total and acid of S. odoratissima. The plant material was collected in Leopoldo de Bulhões/ Goiás and the morpho-anatomical studies and the phytochemical screening were performed using conventional techniques. It was verified that the leaf is hypostomatic, with anomocytic stomata and the epidermis has papillae on the abaxial surface. The mesophyll is dorsiventral and the midrib presents druses of calcium oxalate and secretory cavities. The petiole has a circular vascular system. The root in primary growth presents vascular cylinder with diarchic organization. Phenols, tannins, coumarins, flavonoids, triterpenes/sterols, anthraquinones and anthocyanins were detected in the phytochemical screening of the leaves, and alkaloids, coumarins, saponins and starch were detected in the roots. These results are important parameters for the quality control of the vegetal raw material.Key words: Savannah, quality control, medicinal plants, Rutaceae. INTRODUÇÃOA Spiranthera odoratissima A. St.-Hil. (Rutaceae) é uma planta do Cerrado, popularmente conhecida como Manacá e pertence à família Rutaceae. É um arbusto com...

Zanthoxylum tingoassuiba essential oil (EO) is a complex mixture of organic compounds among which methyl-N-methylanthranilate and sesquiterpene alcohol alpha-bisabolol represent the main compounds. The essential oil antimicrobial activity was studied against bacteria and fungi cells by diffusion disk method and significant activity was observed against S. aureus, S. aureus isolated multi-resistant and the dermathophyte fungi. Essential oil from Zanthoxylum tingoassuiba loaded into DPPC multilamellar liposomes (MLV) was successfully produced through a thin film hydration method with mean diameter of 9.37 +/- 4.69 microm. The EO-loaded liposomes showed adequate sphericity and narrower size distribution than empty liposomes. Results also showed that Zanthoxylum tingoassuiba essential oil can be incorporated in appreciable amounts (43.7 +/- 6.0%) in the prepared vesicular dispersions. A strong interaction between essential oil and lipid bilayer was indicated by a significant decrease in T(m) of the EO-loaded liposomes related to empty vesicles. Essential oil showed incomplete release profile from liposomes, suggesting that EO-loaded liposomes will be useful in pharmaceutical applications to enhance essential oil targeting to cells.

Abstract— Spiranthera (Rutaceae, Galipeeae) is a neotropical genus, recognizable mainly by the presence of trifoliate leaves, pentamerous flowers, exappendiculate filaments, spirally revolute anthers lacking a basal appendage, a campanulate disk, and anelongated gynophore. Species in this genus are mostly sciophilous treelets from South American rainforests, except for Spiranthera odoratissima, the most widespread species, which is a shrub inhabiting savannic formations and showing the widest morphological variation within the genus. In this taxonomic revision we present an extensive morphological analysis of the genus based on data from field work and from herbaria, an identification key, and descriptions and illustrations of the six species here recognized, including a new one from Iquitos, Peru. Also, we present updated information on the geographic distribution of the species, their habitats, and their morphological variability.
