Wuyi　rock　tea　(WRT),　which　is　rich　in　polyphenol　and　has　significant　health　benefits,　is　a　top　tea　variety　in　China.　Five　typical　WRT　samples,　both　extracts(TE)　and　infusions(TI)　were　used　for　the　studies　of　the　polyphenol　profiles　and　antioxidant　activities.　Total　phenolic　contents　in　both　TI　and　TE　were　determined　by　using　the　Folin-Ciocalteu　method,　and　then　caffeine,　catechins　and　teaflavins　were　determined　by　HPLC　method.　Subsequently,　ABTS,　DPPH　and　FRAP　assays　were　used　to　assess　their　antioxidant　activities.　Finally,　Pearson　correlation　analysis　was　used　to　evaluate　the　correlation　between　polyphenol　components　and　antioxidant　activities　of　WRT.　The　results　indicated　that　total　phenol　contents　of　TI　and　TE　were　0.67mg　GAE/mL　and　3.89　mg　GAE/mL;　caffeine　contents　were　126.07‱,　181.86‱;　total　catechins　were　142.49‱,　423.09‱;　total　theaflavins　were　1.14‱,　3.88‱;　ABTS　scavenging　activities　were　6.43　mg　GAE/g,　140.27　mg　GAE/g;　DPPH　scavenging　activities　were　9.14　mg　GAE/g,　182.66　mg　GAE/g;　ferric　reducing　abilities　were　6.18　mg　GAE/g,　101.44　mg　GAE/g.　Moreover,　significant　positive　correlation　between　total　phenolic　contents　of　WRT　and　their　antioxidant　activities　was　found　by　using　Pearson　correlation　analysis(P＜0.05).　This　study　may　be　helpful　for　the　further　understanding　of　the　nutritional　values　of　WRT.　©　2018,　Editorial　Office　of　Journal　of　CIFST.　All　right　reserved.
