摘要

haskap已经在加拿大的许多地理区域成功种植。我们研究了纬度是否对haskap浆果中花青素的积累和总抗氧化能力有任何影响。将测得的品质特性与蓝莓的品质特性进行比较。Haskap‘Aurora’浆果采自加拿大育空地区、不列颠哥伦比亚省、萨斯喀彻温省和新斯科舍省，蓝莓采自新斯科舍。测定了haskap浆果中含量最高的花青素——花青素-3-O-葡萄糖苷（C3G）、总花青素、总多酚、可溶性固形物（°Brix）、pH值、总抗氧化能力和水分含量。结果显示，haskap的总花青素、总酚含量和抗氧化能力分别在88至273 mg C3GE/100 g鲜重（FW）、256至442 mg GAE/100 g FW和27至52µmol TE/g FW之间。液相色谱-质谱（UPLC/MS）分析表明，haskap浆果中所含的C3G高度依赖于收获阶段。在这些样本中，2019年7月19日从育空地区收获的haskap浆果的C3G含量最高。有趣的是，haskap浆果的总花青素含量与低丛蓝莓相当，但高于高丛蓝莓。建议采用多个品种和生长地点进行系统的多年试验，以更好地了解纬度效应。

Effect of growing location on anthocyanin content and total antioxidant capacity of haskap (Lonicera caerulea L.) berry: A preliminary investigation

The haskap has been successfully cultivated in many geographical zones in Canada. We investigated whether the latitude has any impact on the anthocyanin accumulation and total antioxidant capacity in the haskap berry. The measured quality attributes were compared with that of the blueberry. Haskap ‘Aurora’ berries were collected from Yukon, British Columbia, Saskatchewan, and Nova Scotia in Canada, and blueberries were collected from Nova Scotia. Cyanidin-3-O-glucoside (C3G), the most abundant anthocyanin of haskap berry, the total anthocyanins, the total polyphenols, the soluble solids (°Brix), the pH value, the total antioxidant capacity, and the moisture content were determined. The results revealed that the total anthocyanin, total phenolic content, and antioxidant capacity of the haskap range between 88 to 273 mg C3GE/100 g fresh weight (FW), 256 to 442 mg GAE/100 g of FW, and 27 to 52 µmol TE/g FW, respectively. The liquid chromatography-mass spectrometry (UPLC/MS) analysis revealed that the C3G contained in the haskap berry is highly dependent on the harvest stage. Among the samples, the haskap berry harvested on July 19, 2019, from the Yukon had the highest C3G content. Interestingly, the total anthocyanin content of the haskap berry is comparable to that of the lowbush blueberry, but higher than the highbush blueberry. A systematic multi-year experiment employing many cultivars and growing locations is recommended to better understand the latitude effect.
