Summary

<i>Alpinia oxyphylla</i> is a homology of medicine and food. This study aims to investigate the dominant chemical composition and explore the antioxidant properties of the ethanol extract of the leaves and stems of <i>A. oxyphylla</i> (AOE) on juvenile shrimp, <i>Litopenaeus vannamei</i>. An in vitro test showed that AOE and its dominant chemical composition procyanidin B-2 (<b>1</b>) and epicatechin (<b>2</b>) presented DPPH and ABTS radical scavenging activities. A shrimp feeding supplement experiment revealed that shrimp growth parameters and muscle composition were improved significantly when fed with a 200 mg/Kg AOE additive. Meanwhile, the activities of antioxidant enzymes (CAT, GSH-Px, SOD, and T-AOC) in serum and the liver and the expression of related genes (<i>LvMn-SOD</i>, <i>LvCAT</i>, <i>LvproPo</i>, and <i>LvGSH-Px</i>) were enhanced with various degrees in different AOE additive groups while the content of MDA was significantly decreased. Moreover, the antioxidative effect of AOE additive groups on shrimp was also observed in an acute ammonia nitrogen stress test.
