Embodiment 1
[0039] Get the grape skin raw material, add ethyl acetate and 70% ethanol with a volume ratio of 1:2 after pulverizing it, heat and reflux for extraction twice, the first time is 1.5 hours, the second time is 1 hour, and the filtrates are combined to obtain extract I. Add 70% ethanol to the residue, heat and reflux to extract twice, the first time for 1 hour, and the second time for 0.5 hours, the filtrates are combined to obtain the extract II; the combined extracts I and II are concentrated into an extract, and the extract is dissolved with 50% methanol , using macroporous resin AB-8 for separation, first eluted with 65% ethanol to obtain eluent I; then eluted with 85% ethanol at a flow rate of 2.5BV / h to obtain eluent II, recovered , concentrated under reduced pressure, dried, that is.
[0040] After testing, the resveratrol content is 12.01%, and the anthocyanin content is 4.46%.
Embodiment 2
[0042] Get the grape seed raw material, add ethyl acetate and 70% ethanol with a volume ratio of 1:2 after pulverizing it, heat and reflux to extract 2 times, the first time is 1.5 hours, the second time is 1 hour, and the filtrates are combined to obtain extract I. Add 70% ethanol to the residue, heat and reflux to extract twice, the first time for 1 hour, and the second time for 0.5 hours, the filtrates are combined to obtain the extract II; the combined extracts I and II are concentrated into an extract, and the extract is dissolved with 50% methanol , using macroporous resin X-5 for separation, first eluted with 70% ethanol to obtain eluent I; then eluted with 90% ethanol at a flow rate of 2BV / h to obtain eluent II, recovered, Concentrate under reduced pressure, dry, that is.
[0043] After testing, the resveratrol content was 11.18%, and the anthocyanin content was 5.53%.
