| Zanthoxylum rhoifolium Lam is a plant popularly used as antimicrobial, for malaria and inflammatory treatment. The essential oil of Z. rhoifolium was extracted and its cytotoxic effects against HeLa (human cervical carcinoma), A-549 (human lung carcinoma), HT-29 (human colon adenocarcinoma), Vero (monkey kidney) cell lines and mice macrophages were evaluated. Some of the terpenes of its essential oil (ß-caryophyllene, alpha-humulene, alpha -pinene, myrcene and linalool) were also tested to verify their possible influence in the oil cytotoxic activity. The results obtained permitted to confirm that the essential oil is cytotoxic against tumoral cells (CD50 = 82.3, 90.7 and 113.6 µg/ml for A-549, HeLa e HT-29 cell lines, respectively), while it did not show... |

| Este trabalho consiste no levantamento das espécies dos gêneros Zanthoxylum e Esenbeckia ocorrentes em Pernambuco. Foi baseado nos caracteres morfológicos das espécies obtidas em campo e nos materiais de 16 herbários brasileiros. Foram registradas nove espécies de Zanthoxylum: Z. caribaeum Lam., Z. fagara (L.) Sarg., Z. gardneri Engl., Z. hamadryadicum Pirani, Z. monogynum A. St.-Hil., Z. petiolare A. St.-Hil & Tul., Z. rhoifolium Lam., Z. stelligerum Turcz. e Z. syncarpum Tul. Para Esenbeckia foram verificadas cinco espécies: E. almawillia Kaastra, E. febrifuga (A. St.-Hil.) Juss. ex Mart., E. garandiflora Mart., E. leiocarpa Engl. e E. pilocarpoides Kunth. Para reconhecimento das espécies são apresentadas chaves de identificação, descrições,... |

| ABSTRACT Zanthoxylum rhoifolium Lam. (Rutaceae) has been traditionally used in the treatment of microbial infections and parasitic diseases. In the present study, the antileishmanial effect induced by the ethanol extract of stem barks from Z. rhoifolium (ZR-EEtOH) and its n-hexane fraction (ZR-FHEX) on infection and infectivity of murine macrophages by promastigote forms of Leishmania amazonensis were investigated. In different set of experiments, macrophages or promastigotes were pretreated with ZR-EEtOH or ZR-FHEX at non-lethal concentrations for 24 hours, and then macrophages were submitted to infection by promastigotes. Moreover, their effects on activation of macrophages, as well as on the DNA content, size and number of promastigotes by flow... |
