In vitro 在该领域,Stellera chamaejasme L. (Thymelaeaceae) 是中国北部和西部草原上最有毒且对生态构成威胁的杂草之一。通过对该植物根提取物的生物活性引导分离,成功分离出八种黄酮类化合物1-8,其结构通过光谱分析确定。除了7-甲氧基neochaejasmin A (4) 和 (+)-epiafzelechin (5) 外,所有化合物对拟南芥(Arabidopsis thaliana) 幼苗展现出强烈的植物毒性活性。其中,neochamaejasmin B (Neochamaejasmine B,1)、mesoneochamaejasmin A (2)、chamaejasmenin C (3)、genkwanol A (6)、daphnodorin B (7) 和 dihydrodaphnodorin B (8) 对幼苗生长的抑制作用,其半抑制浓度(IC50) 分别为6.9、12.1、43.2、74.8、7.1 和 27.3μg/mL,并且这些化合物均破坏了根部发育[1]。
