Aspectos agronômicos, teor de ipolamida e verbascosídeo de clones de gervão-roxo [Stachytarpheta cayennensis (rich.) vahl]

Abstract

O gervão-roxo [Stachytarpheta cayennensis (Rich.) Vahl] é uma espécie nativa de ampla ocorrência no Brasil e de uso medicinal, comumente encontrada em bordas de matas e beiras de estradas. Existem poucos estudos sobre esta espécie, principalmente informações agronômicas, onde as plantas medicinais se diferenciam de outras culturas agrícolas pela necessidade de inter-relacionar a produção de massa-seca com a produção de princípio ativo. Sendo assim, o objetivo deste trabalho foi avaliar aspectos agronômicos e o teor de ipolamida e verbascosídeo em 15 clones de Stachytarpheta cayennensis (Rich.) Vahl oriundos de 4 municípios brasileiros, e cultivados em Botucatu/SP. O delineamento experimental utilizado foi em blocos casualizados contendo 6 blocos e 15 tratamentos que foi constituído por clones. Foram avaliados massa fresca e seca de parte aérea e raiz, teor de ipolamida e verbascosídeo no extrato seco de parte aérea. Para os teores dos princípios ativos e produção de massa seca, os resultados no clone BR e BT foram superiores em relação aos demais clones (A2, A3, A7, A9, A15, P4, P6, P7, P8, P11, P14, P16 e P19) sendo respectivamente, teor de 5,16% de ipolamida e 4,91% de verbascosídeo, e de 6,19% de ipolamida e 3,85% de verbascosídeo. Gervão-roxo [Stachytarpheta cayennensis (Rich.) Vahl] is a native species, widely found in Brazil and with medicinal use. It is commonly found on the edges of forests and roadsides. There are few studies about this species, especially focused on agronomic information, where medicinal plants differ from other crops due to the need to interrelate dry mass production with active ingredient content. Thus, the aim of this study was to evaluate the agronomic aspects and the ipolamide and verbascoside content in 15 Stachytarpheta cayennensis (Rich.) Vahl clones from four Brazilian municipalities, cultivated in Botucatu/SP. The experimental design was in randomized blocks containing 6 blocks and 15 treatments that consisted of clones. Evaluations were carried out on fresh and dry mass from the aerial part and from the root, ipolamide and verbascoside contents in the dry extracts from the aerial part. For the active ingredient contents and dry mass production, the results from clones BR and PT were superior compared to the other clones (A1, A2, A3, A4, A5, P1, P2, P3, P4, P5, P6, P7 and P8), resulting in 5.16% ipolamide and 4.91% verbascoside content, and 6.19% ipolamide and 3.85% verbascoside, respectively.
