- Abstract:
- Objective To explore the preparation technology of extracting different parts from the wild jujube and make a research on the antioxidant activities. Method To optimize the extraction preparation tehcnology with the total flavonoids as the index and prepare the extracts and evaluate the ingredients with the epicatechin, hesperidin, quercitrin, isoquercitrin, kaempferol -3 - o - rutin, quercetin -3 - o - acacia, glucoside, quercetin -3 - o - toy - l - arabinoside - ( 1 → 2)- leben - l - rhamnoside as the index component of flavonoid. Jujube rensaponin A, jujube rensaponin B, betulinic acid,spinosin serve as the index component of saponins to evalute the ingrediants. A research on total reduction capacity, hydroxyl free radical scavenging capacity, DPPH free radical scavenging capacity is done with the Vc used a positive control. Result Jujube kernel, jujube pulp, jujube surface and jujube leaf all had antioxidant activities in vitro, and the totalreducing capacity of extracts from different parts was jujube leaf > jujube kernel > jujube surface > jujube flesh compared with Vc. DPPH free radical scavenging capacity was jujube kernel > jujube flesh > jujube leaf > jujube surface. The scavenging ability of hydroxyl radical ( ? OH) was jujube surfacer > jujube leaves > jujube flesh > jujube kernel.Conclusion The extracts from different parts of the wild jujube have antioxidant activity in vitro.
