从红三叶草（Trifolium pratense）的根分泌物中分离得到3种对寄生杂草三叶草肉苁蓉（Orobanche minor）种子萌发有促进作用的物质，并对其结构进行了测定。其中一个被鉴定为alectrol，另一个是一个新的独脚金醇相关化合物，命名为列当醇。根据质谱和核磁共振谱数据，初步认为列当醇是独脚金醇的异构体。这是列当属植物种子萌发促进剂的首次报道。真正的寄主植物。还描述了分析独脚金内酯的GC-MS技术。(C)1998由Elsevier Science Ltd.出版。保留所有权利。
Three seed germination stimulants for a parasitic weed, clover broomrape (Orobanche minor), were isolated from the root exudate of its host, red clover (Trifolium pratense) and structures of the two of the stimulants were determined. One was identified as alectrol and the other was a novel strigol-related compound which was named orobanchol. Orobanchol was tentatively proposed to be a strigol isomer based on its MS and NMR spectral data. This is the first report on germination stimulants of Orobanche spp. from genuine host plants. GC-MS techniques to analyze strigolactones are also described. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
