Morfoanatomia de folhas e caules de Passiflora edulis Sims, Passifloraceae

Abstract

RESUMO:Passiflora edulis Sims, espécie vegetal empregada na medicina popular e amplamente cultivada no território nacional, tem suas folhas e seus caules, muitas vezes utilizados como adulterante de amostras comerciais da droga vegetal oficializada no país também conhecida como maracujá, Passiflora alata Curtis. Caracteres morfoanatômicos de folhas e de caules de P. edulis, foram descritos e documentados. Dentre os caracteres auxiliares na distinção entre a droga oficial e os órgãos aéreos de P. edulis podem-se destacar o contorno da lâmina foliar, a forma da nervura mediana em secção transversal, o número e a localização de nectários extraflorais e, o indumento.Unitermos: Passiflora edulis, morfologia, anatomia, folhas, caule.ABSTRACT: "Leaf and stem morphoanatomy of Passiflora edulis Sims, Passifloraceae". Passiflora edulis Sims, vegetal species employed in the Brazilian traditional medicine and broadly cultivated across its territory, has its leaves and stems often used as an adulterant for commercial samples of the crude drug Passiflora alata Curtis, officially known in Brazil as "maracujá". Morphoanatomic data from leaves and stems in P. edulis were described and documented. Amongst these characteristics, the shape of the foliar blade, the shape of the midrib in transverse section, the number and the location of the extrafloral nectaries and the indumentum are all emphasized.

Comparative study of Passiflora taxa leaves: I. A morpho-anatomic profile

“…edulis has been widely cultivated in Brazil and Moraes et al (1997) reported that leaves and stems have been used as an adulterant for P. alata, which was included in the first three editions of the Brazilian Pharmacopoeia and was official in the country at that time. Moreover, in Brazil, several Passiflora species are popularly known as 'maracujá', which reinforces the importance of identification and differentiating between them (Beraldo and Kato, 2010). Morphological characteristics are very important for correct species identification.…”

“…However, the literature discusses this topic only at the species level and not at the form level. Besides, the reports are inconsistents (Pereira et al, 2009;Beraldo and Kato, 2010;Farmacopeia, 2010;Barbosa et al, 2013;Leite et al, 2013;Farias, 2014;Cervi, 1997).…”

“…A flor do maracujá azedo é hermafrodita e as folhas são simples, alternadas, trilobadas, inteiras ou bilobadas, de base cordada, ápice acuminado e margem serrilhada, nervura mediana biconvexa com saliência arredondada na face abaxial (BERALDO; KATO, 2010;SEAGRI, 2013 …”
