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.
