RESUMO

Various models addressing quantitative analyses of ethnobotanical and ethnopharmacological data have been proposed in the last decade, with most of them based on informant consensus. The present work tested the efficiency of different methodological strategies, comparing the Syndromic Importance Value (SIV) with priority criteria based on the free-listing technique as well as two random forms of choosing plants using ethnodirected approaches. Efficiency was evaluated by assaying the tannin and flavonoid contents of plants associated with woundhealing and anti-inflammatory activities. The study interviewed members of a rural community in the Caatinga region of northeastern Brazil and verified that the SIV was an efficient tool for identifying plants with high tannin content. However, no relationships were observed between plants used by the community to treat inflammation or healing with their flavonoid contents. Thus, identifying Caatinga medicinal plants known and/or used for their anti-inflammatory and healing capacities is a good criterion for identifying species with high levels of tannins, although these same criteria are not useful for identifying plants with high flavonoid contents
