- Abstract
Ethnopharmacological records indicate several therapeutic properties attributed to the decoction of macela inflorescences, such as, for example, effective in combating high blood pressure and high cholesterol, cramps of nervous origin, for wound cleaning, diarrhea, as well as anti-inflammatory and gastrointestinal disorders. The macela on Good Friday is collected near highways and may increase the risk of human contamination with heavy metals. The Cd, Cu, Pb and Zn metals are released during different road transport operations, such as combustion, tire wear, oil leakage, wear of brake pads and discs, radiators, etc. The objective of this study was to quantify the levels of Al and heavy metals such as Cu, Mn, Ni, Pb and Zn in the infusion of macela collected at sites influenced by road traffic. The macela flowers were collected along the margins of the BR-282 highways; SC-390 and SC-114 and their control areas (without traffic), separated from the branches and dried in a circulation oven at 65ºC. The infusion process was performed according to Anderson's protocol (1999), and quantification of Al, Cu, Mn, Ni and Zn in ICP-OES and Pb in HR-CS AAS. On average the infusions of the macela samples collected at the borders of BR 282 presented the highest levels of Al, Cu, Ni, Mn and Zn. There was no statistical difference between Pb contents in the macela collected on the different highways and the witnesses. The consumption of macela tea collected near highways can result in a risk to human health.
