The Phytochemistry and Pharmacology of Butia sp.: A Systematic Review and an Overview of the Technological Monitoring Process.

The Butia sp. are native South America trees, whose fruits are consumed in natura and have significant biological properties; however, trees of this genus plant are in danger of extinction. A systematic review of the literature and a technological overview were carried out to summarize the available evidence on the therapeutic uses and the phytochemical compounds of Butia sp. The following electronic databases were researched: MedLine (PubMed), Web of Science, Scopus, Scielo, and the gray literature. Furthermore, the online system such as the US Patent and Trademark Office, Espacenet, National Institute of Industrial Property, and Google Patents were accessed to obtain patent data. The inclusion criteria were articles that describe either the therapeutic uses of Butia sp. (antimicrobial activity, antioxidant activity, anti-inflammatory activity, antineoplastic activity) or studies describing phytochemical compounds of Butia sp. A limited amount of manual search was also undertaken. Reference lists were scanned to identify other relevant studies, and requests for unpublished data were conducted to people working in the field. Among 12 papers and 14 patents, 9 complete texts of scientific articles and 1 patent were scrutinised by two reviewers. We concluded that Butia has shown some antioxidant, anti-inflammatory, and antimicrobial activity, and its use could have important implications for future therapeutic uses. Although there is evidence of pharmacological potential from in vitro studies, clinical studies must be conducted to confirm the effectiveness of Butia sp. The evidence of its therapeutic uses has not been extensively studied yet, and the available evidence still needs further confirmation. Copyright © 2017 John Wiley & Sons, Ltd.
