R TYPE OF RESVERATROL DIMER, PREPARATION PROCESS THEREFOR AND PURPOSE THEREOF IN LOWERING BLOOD SUGAR LEVEL

摘要

The present invention relates to the field of natural pharmaceutical chemistry, and in particular, to a resveratrol dimer (7R,8R)-trans-δ-viniferin (I), a preparation process therefor and a purpose thereof in lowering a blood sugar level. According to the present invention, an R type of resveratrol dimer is separated from the resveratrol dimer by using high-speed countercurrent chromatography. Pharmacodynamic tests proved that the R type of resveratrol dimer has a better effect in lowering a blood sugar level than a racemate.
