ILUSTRAÇÃO DE CARACTERES MICROSCÓPICOS DE DROGAS VEGETAIS PARA O CONTROLE DE QUALIDADE FARMACOGNÓSTICO. IV. JABORANDI (Pilocarpus pennatifolius LEM., RUTACEAE)

This work integrates a series of this journal, which displays microscopic characters of vegetal drugs, as an applicable resource that complements anatomical description. The species herein is Pilocarpus pennatifolius Lem., one among various Rutaceae popularly known as jaborandi. The vegetal drug consists of compound leaves or subunits, called leaflets, which are rich in imidazole alkaloids, mainly pilocarpine. Samples of mature leaves were collected from taxonomically identified specimens at the Jardim Botânico Municipal de Curitiba. The material was fixed in FAA, free-hand sectioned or embedded in glycol-methacrylate, sectioned by microtome and stained. The illustrations show hypostomatic leaf, anomocytic stomata, striate cuticle, unicellular non-glandular trichomes, multicellular capitate trichomes, dorsiventral mesophyll, midrid and petiolule biconvex in transection, calcium oxalate druses and secretory cavities
