Avaliação da qualidade de amostras comerciais de leite de janaguba (Himatanthus drasticus (Mart.) Plumel) em Fortaleza - Ceará

Abstract

Quality assessment of commercial samples of janaguba’s milk (Himatanthus drasticus (Mart.) Plumel) in Fortaleza - Ceará. The herbal medicines made from janaguba milk (Himatanthus drasticus (Mart.) Plumel), used to treat gastric ulcer, cancer and other diseases, and arewidely sold in the public markets of Fortaleza (CE). However, records mention that it is common to make fake copies of the milk by using mango tree latex (Hanconia speciosa Gomes). This study aimed to evaluate the chemical, physical-chemical and microbiological quality of commercial samples of janaguba milk. Ten commercial samples were purchased from a Fortaleza market; four authentic samples of janaguba latex were obtained from the Araripe plateau, and one mango tree latex sample was obtained in Paracuru (CE). We determined the general appearance, density, pH, dry residue, sedimentation volume, chromatographic profile and microbiological qualities. Results showed high microbiological contamination in the commercial preparations and evidence of tampering in six of these samples, which indicates the need for an urgent implementation of an effective pharmacovigilance strategy for herbal medicines in order to make its consumption more secure and rational.
