Preparação e controle de qualidade físico-química de matéria-prima vegetal de flor sabugueiro (Sambucus nigra L.)

Abstract

Elderberry flowers (Sambucus nigra L.) can be used to treat symptoms of colds and flu. To guarantee the quality of the raw material it is necessary to have quality control trials to establish standards in order to promote safety and final product effectiveness. The present study aimed to determine the adequacy of drying conditions to optimize the quality of plant material for tea preparation elderberry The methodology applied in the work was based on the control tests of physicochemical quality of the Brazilian Pharmacopoeia. The sample of plant drug (flowers) dried at 40oC for 72h was analyzed and obtained values ​​compatible with the recommendations pharmacopoeias for moisture content (8.7%) and total ash (6.97%); the infusion showed a average of 0.46% of dry residue and the average pH value was 5.12, the average value of polyphenols totals was 0.15%. Through the parameters used in this study, it is possible to create measures that ensure the use of the plant drug with quality, as long as it has all its supervised processing, from planting to the final product.
