摘要 从皂角苷混合物的碱性水解产物中获得了三种化合物,一种酸和两种糖苷酸,它们来源于木犀草皂苷的酰基部分。根据化学和光谱证据,它们被鉴定为 3,5-dihydroxy-6-methyl-octanoic acid、3,5-dihydroxy-6-methyl-octanoic acid 5-O-α-L-arabinofuranoside 和 5- O -α- L -rhamnopyranosyl-(1 → 2)-α- L -arabinofuranoside。事实上,第一种化合物被分离出来并表征为其内酯形式。FDMS 可用于提供有关独特酸和糖苷酸的 M 的信息。

This present invention provides for a genetically modified host cell, or a cell-free reaction system, and related methods and materials for the biocatalytic production of an alkyl lactones from a hydroxy fatty acid, or natural alkyl lactones and esters from sugars using non-natural combinations of enzymes.
