Abstract

The invention discloses a mogrol derivative monomer as well as a preparation method and application thereof, and belongs to the technical field of structural modification of plant active ingredients. The mogrol derivative monomer is a compound shown as a formula 2, and the invention also discloses a preparation method and application of the mogrol derivative monomer. According to the mogrol derivative monomer disclosed by the invention, the C-24 site of mogrol is selectively derived into a single carboxyl group on the premise of keeping chirality of each site on a tetracyclic parent nucleus of mogrol and not changing a functional group, and the high reaction activity of the carboxyl group is convenient for further derivatization.

Description

technical field [0001] The invention relates to a mogroside alcohol derivative monomer, a preparation method and application thereof, and belongs to the technical field of structural transformation of plant active ingredients. Background technique [0002] Luo Han Guo, scientific name Siraitia grosvenorii (Swingle.) C. Jeffrey, is the dried fruit of the perennial liana of Cucurbitaceae, which has the effects of moistening the lungs and laxative, relieving cough and reducing phlegm. Mogrol, the English name mogrol, is the parent nucleoside element of mogrosides ⅠA1, ⅠE1, ⅡE, Ⅲ, Ⅳ, ⅣVE, Ⅴ and simonoside I, etc., and belongs to the cucurbitane-type tetracyclic triterpenes. Hydroxyl, high oxidation, steric effects and other factors make it difficult to carry out chemical modification. [0003] Mogrosvenol is a product that enters the blood after metabolism in the body of Luo Han Guo. In the existing research, the C-24 and 25-position o-hydroxyl structure of mogrosanol can be o...
