荔枝果皮中含有大量的酚类物质，这些酚类物质具有多种生物活性。本工作的目的是确定的品种差异，酚配置文件和抗氧化活性的LFP从9个市售品种。总酚和黄酮含量范围从9.39至30.16毫克没食子酸当量/克鲜重（FW）和从7.12至23.46毫克儿茶素当量/克FW，分别。总花青素含量范围为1.77至20.94毫克花青素-3-葡萄糖苷当量/100克FW。结果表明，花青素-3-芸香糖苷、花青素-3-葡萄糖苷、锦葵色素-3-葡萄糖苷是花青素的主要成分，占总花青素的68.8%~ 100%，总原花青素含量为4.35 ~ 11.82 mg/g FW。原花青素B2、表儿茶素、A型原花青素三聚体和原花青素A2在9个荔枝品种中均有检测。结果表明，其抗氧能力和清除DPPH自由基能力分别为430.49 ~ 1752.30 μmol TE/100 g FW和4.70 ~ 11.82 mg/g（IC 50）。这些结果表明，供试品种之间的植物化学成分和抗氧化活性存在显着差异。了解不同品种LFP的酚类特征和抗氧化活性，可以了解其在促进健康方面的潜在应用。
Litchi fruit pericarp (LFP) contains significant amounts of phenolics which have been found to exhibit diverse biological activities. The purpose of this work was to determine the varietal differences in phenolic profiles and antioxidant activity of LFP from nine commercially available cultivars. The total phenolic and flavonoid contents ranged from 9.39 to 30.16 mg gallic acid equivalents/g fresh weight (FW) and from 7.12 to 23.46 mg catechin equivalents/g FW, respectively. The total anthocyanin contents ranged from 1.77 to 20.94 mg cyanidin-3-glucoside equivalents/100 g FW. Three anthocyanins, including cyanidin-3-rutinoside, cyanidin-3-glucoside, malvidin-3-glucoside, were detected, and cyanidin-3-rutinoside was the predominant constituent which contributes from 68.8% to 100% to total anthocyanins, The total procyanidin contents ranged from 4.35 to 11.82 mg epicatechin equivalents/g FW. Procyanidin B2, epicatechin, A-type procyanidin trimer, and procyanidin A2 were detected in all nine litchi varieties. The oxygen radical absorbance capacity activities and DPPH radical-scavenging activities ranged from 430.49 to 1752.30 μmol TE/100 g FW and from 4.70 to 11.82 mg/g (IC50), respectively. These results indicate that there are significant differences in phytochemical profiles and antioxidant activity among the tested varieties. Knowing the phenolic profiles and antioxidant activity of LFP of different varieties gives the insights into its potential application to promote health.
