Lapachol is a natural naphthoquinone with several significant biological activities. This study aims to analyze the longitudinal distribution of lapachol in four species of Handroanthus spp. The Handroanthus serratifolius (Vahl.) S. O. Grose and Handroanthus impetiginosus (Mart. Ex DC.) Mattos species showed higher yields of lapachol than Handroanthus ochraceus (Cham.) Mattos and the Handroanthus capitatus (Bureau & K. Schum.) Mattos. The Handroanthus spp. species may be considered promising to provide natural-originated lapachol production valued by the chemical and pharmaceutical industry.

拉帕胆在ipê种（Handroanthus spp。）茎上的纵向分布

拉帕胆是具有几种重要生物学活性的天然萘醌。本研究旨在分析拉帕酚在4种Handroanthus spp中的纵向分布。所述Handroanthus serratifolius（干旱胁迫下连翘）SO格罗斯和Handroanthus impetiginosus（玛特。实施例DC。）物种Mattos的显示拉帕醇比的更高的产率Handroanthus赭（湛）Mattos的和Handroanthus capitatus（局＆K.舒姆）Mattos的。该Handroanthus属。可以认为这些物种有望提供化学和制药业珍视的天然来源的拉帕酚。
