Contents of total phenolics, total flavonoids, total proanthocyanidins, and antioxidant activities of pulp extracts of 32 litchi cultivars.

Data were presented as the mean ± S.D. (n = 3) on a dry weight (DW). Total phenolics were calculated as mg gallic acid equivalent (mg GAE/g DW). Total flavonoids were calculated as mg catechin equivalent (mg CE/g DW). Total procyanidins were calculated as mg procyanidin B2 equivalent (mg PB2E/g DW). The scavenging of DPPH and ABTS radicals were calculated as μg vitamin C equivalent (μg VcE/g DW), respectively.Contents of total phenolics, total flavonoids, total proanthocyanidins, and antioxidant activities of pulp extracts of 32 litchi cultivars.实验数据以平均值±标准差（mean ± S.D.）表示，每组平行重复数为n=3，所有指标均以干重（dry weight, DW）为计量基准。总酚含量以没食子酸当量（gallic acid equivalent, GAE）计，单位为mg GAE/g DW；总黄酮含量以儿茶素当量（catechin equivalent, CE）计，单位为mg CE/g DW；总原花青素含量以原花青素B2当量（procyanidin B2 equivalent, PB2E）计，单位为mg PB2E/g DW。DPPH自由基与ABTS自由基的清除能力分别以抗坏血酸当量（vitamin C equivalent, VcE）计，单位为μg VcE/g DW。本数据集涵盖32个荔枝品种果肉提取物的总酚、总黄酮、总原花青素含量及抗氧化活性数据。
