Chemistry

The plant contains dehydro-alpha-lapachone (DAL) which inhibits vessel regeneration, interferes with vessel anastomosis, and limits plexus formation in zebrafish. DAL also controlled the development of the fungi rice blast, tomato late blight, wheat leaf rust, barley powdery mildew and red pepper anthracnose (Colletotrichum coccodes (Wallr) S Hughes). The chemical was particularly effective in suppressing anthracnose.
