用毛鳞假单胞菌接种海茅根茎片，可诱导产生4种线状呋喃香豆素、植物抗毒素、补骨脂素、黄毒素、草加藤素和去甲基亚红素，其中前3种已被报道为海茅药材的主要成分。对接种、紫外线照射和未照射的西芹根切片进行的时间过程研究表明，胁迫处理后呋喃香豆素浓度显著增加。生药中的补骨脂素、黄毒素和黄瓜甲素被认为是加工过程中产生的应激代谢物，至少部分是这样。1997爱思唯尔科学有限公司
Inoculation of Glehnia littoralis root slices with Pseudomonas cichorii induced the production of four linear furanocoumarin phytoalexins, psoralen, xanthotoxin, bergapten and demethylsuberosin, of which the former three have been reported as constituents of the crude drug Glehnia root. A time-course study on the respective P. cichorri-inoculated, UV-irradiated and non-irradiated root slices showed greatly increasing concentrations of the furanocoumarins after stress treatment. Psoralen, xanthotoxin and bergapten in the crude drug were considered, at-least in part, to be stress metabolites produced during processing. (C) 1997 Elsevier Science Ltd.
