It is evident from various epidemiological studies that consumption of fruits and vegetables is essential to maintain health and in the disease prevention. Present study was designed to examine phenolic contents and antioxidant properties of three varieties of Crataegus pinnatifida (Chinese hawthorn). Shanlihong variety exhibited elevated levels of total phenolics and flavonoid contents, including free and bond phenolics. Procyanidin B2 was most abundant phenolic compound in all samples, followed by epicatechin, chlorogenic acid, hyperoside, and isoquercitrin. The free ORAC values, and free hydro-PSC values were 398.3-555.8 μmol TE/g DW, and 299.1-370.9 μmol VCE/g DW, respectively. Moreover, the free cellular antioxidant activity (CAA) values were 678-1200 μmol of QE/100 g DW in the no PBS wash protocol, and 345.9-532.9 μmol of QE/100 g DW in the PBS wash protocol. C. pinnatifida fruit could be valuable to promote consumer health.
从各种流行病学研究中可以明显看出，食用水果和蔬菜对于维持健康和预防疾病至关重要。本研究旨在检测三种山楂（山里红）品种的酚类成分和抗氧化特性。山里红品种的总酚和黄酮含量较高，包括游离酚和结合酚。原花青素B2是所有样品中含量最丰富的酚类化合物，其次是表儿茶素、绿原酸、金丝桃苷和异槲皮苷。游离氧自由基吸收能力（ORAC）值和游离羟基自由基清除能力（hydro-PSC）值分别为398.3 - 555.8 μmol TE/g DW和299.1 - 370.9 μmol VCE/g DW。此外，在无磷酸盐缓冲盐水（PBS）洗涤方案中，游离细胞抗氧化活性（CAA）值为678 - 1200 μmol QE/100 g DW，在PBS洗涤方案中为345.9 - 532.9 μmol QE/100 g DW。山楂果实对于促进消费者健康可能具有重要价值。
