Abstract

The biosynthetic pathway to natural pyrethrins in Chrysanthemum cinerariaefolium seedlings was studied using [1-13C]d-glucose as a precursor, with pyrethrin I isolated using HPLC from a leaf extract. The 13C NMR spectrum of pyrethrin I from the precursor-administered seedlings indicated that the acid moiety was biosynthesized from d-glucose via 2-C-methyl-d-erythritol 4-phosphate, whereas the alcohol moiety was possibly biosynthesized from linolenic acid.

摘要

以[1-¹³C]d-葡萄糖为前体，研究了除虫菊幼苗中天然除虫菊酯的生物合成途径，通过高效液相色谱法从叶片提取物中分离出除虫菊酯I。给幼苗施用前体后得到的除虫菊酯I的¹³C核磁共振谱表明，酸部分是由d-葡萄糖通过2-C-甲基-d-赤藓糖醇4-磷酸生物合成的，而醇部分可能是由亚麻酸生物合成的。
