Emerging buds of were found to accumulate the alkaloid haemanthamine () at high concentrations, exceeding that of narciclasine (), the most abundant constituent in bulbs of the plant. A phytoactivity screening assay demonstrated the novel phytotoxicity of haemanthamine against (radish), (lettuce), (red wheat), (tomato), (cucumber), (Morning glory), and (lentil). Haemanthamine () phytotoxicity was found to exceed that of the commercial herbicide glyphosate and less toxic than narciclasine ().
研究发现，正在萌发的 植株中积累了高浓度的生物碱血根碱（），超过了该植物鳞茎中含量最丰富的白屈菜碱（）。植物活性筛选试验表明，血根碱对萝卜（）、生菜（）、红小麦（）、番茄（）、黄瓜（）、牵牛花（）和扁豆（）具有新型的植物毒性。血根碱（）的植物毒性大于商业除草剂草甘膦，小于白屈菜碱（）。
