Agronomical and phytochemical aspects of fafia

Aspectos fitotécnicos e fitoquímicos de acessos de fáfia

The medicinal species fafia (Hebanthe eriantha), is a product of extractivism in the region of the Paraiba Valley, São Paulo state, Brazil, with endangered genetic variability. This study did an agronomical characterization and an analysis of active compounds of five accessions. This research is a partnership of UNESP-Botucatu Medicinal Plants Laboratory, Paraiba Valley Center (APTA) and CPQBA-UNICAMP Agrotechnological Division. A field experiment using completely random blocks with five accessions and seven replications was used. The stem and leaf wet/dry weights, root wet/dry weight, length of the longest stem, foliar area, foam index and pfaffic acid content samples were evaluated. Accession I1800 had root dry weight, stem and leaf dry weight, and foliar area greater than other accessions (176.16 g/plant, 7.301 kg/plant, 155.04 cm² ). Pfaffic acid content was similar to other accessions (0.640-0.366 %mm-1) Among all five accessions, there is a positive correlation among the foliar area and stem and leaf dry weight and between the foliar area and root dry weight.
