Abstract
ETHNOPHARMACOLOGICAL RELEVANCE
The stem barks of Lafoensia pacari have been traditionally used not only by South Amerindians but also by Brazilian and Paraguayan populations for treating a variety of unhealthy conditions to which their biological potential has been scientifically documented in several reports over the last decade. Although its anticancer usage is also popular, no scientific support for such activity has been found.
AIM
To provide scientific evidence for the anticancer popularity of Lafoensia pacari.
MATERIALS AND METHODS
Extracts prepared according to the popular use along with a methanol extract and its four fractions were produced from Lafoensia pacari stem barks. The chromatogram profile of each one was obtained by HPLC. Several tumor cell lines were exposed to these solutions in in vitro assays and the effects evaluated by morphological, growth, and cell cycle status changes.
RESULTS
High toxicity determined by the lactate dehydrogenase levels with a significant drop in the cell proliferation index were found for all cell lines included in this study after exposition to Lafoensia pacari extract and fractions. The morphological features along with the expression of annexin V have strongly suggested apoptosis induction, which has been confirmed by G0/G1 cell cycle arrest.
CONCLUSIONS
The data have clearly shown that exposition of human tumor cell lines to Lafoensia pacari stem barks extract leads to apoptosis induction due to cell cycle arrest in G0/G1 phases, supporting its anticancer use.
