We carried out a qualitative and quantitative analysis of the phytochemical composition of the fruits of large cranberry cultivars 'Ben Lear', 'Bergman', 'Kalnciema agra', 'Lemunyon', 'Pilgrim', 'Stevens', and 'Tina' grown in Latvian climatic conditions. The following predominant compounds were found in cranberry fruit samples: peonidin-3-O-galactoside, peonidin-3-O-arabinoside, cyanidin-3-O-galactoside, cyanidin-3-O-arabinoside, myricetin-3-galactoside, quercetin-3-galactoside, quercetin-3-α-L-arabinofuranoside, quercetin 3-rhamnoside, ursolic acid, and oleanolic acid. During the berry ripening period (from 16 August until 15 September), a trend of decreasing amounts of compounds was found in the fruit samples of the studied cranberry cultivars: the total amount of proanthocyanidins decreased by 1.3 times, the total amount of the identified flavonols decreased by 1.3 times, the total amount of triterpenoids decreased by 1.2 times, and the total amount of chlorogenic acid decreased by 1.7 times. During the period from 16 August until 15 September, the total amount of anthocyanins in the cranberry fruit samples increased by 2.6 to 17 times. The highest total amount of anthocyanins (5305.80 ± 27 µg/g) was detected in fruit samples of the cranberry cultivar 'Kalnciema agra' collected on 15 September. The amount of biologically active compounds in cranberry fruit samples varies during berry ripening. Thus, the choice of the picking time is one of the factors that determines the phytochemical composition of raw cranberry material.
我们对在拉脱维亚气候条件下种植的大果蔓越莓品种‘Ben Lear’、‘Bergman’、‘Kalnciema agra’、‘Lemunyon’、‘Pilgrim’、‘Stevens’和‘Tina’的果实进行了植物化学成分的定性和定量分析。在蔓越莓果实样本中发现了以下主要化合物：芍药素 - 3 - O - 半乳糖苷、芍药素 - 3 - O - 阿拉伯糖苷、矢车菊素 - 3 - O - 半乳糖苷、矢车菊素 - 3 - O - 阿拉伯糖苷、杨梅素 - 3 - 半乳糖苷、槲皮素 - 3 - 半乳糖苷、槲皮素 - 3 - α - L - 阿拉伯呋喃糖苷、槲皮素3 - 鼠李糖苷、熊果酸和齐墩果酸。在浆果成熟期（8月16日至9月15日），在所研究的蔓越莓品种的果实样本中发现化合物含量呈下降趋势：原花青素总量下降了1.3倍，已鉴定的黄酮醇总量下降了1.3倍，三萜类化合物总量下降了1.2倍，绿原酸总量下降了1.7倍。在8月16日至9月15日期间，蔓越莓果实样本中的花青素总量增加了2.6至17倍。9月15日采集的蔓越莓品种‘Kalnciema agra’的果实样本中检测到最高的花青素总量（5305.80±27μg/g）。蔓越莓果实样本中生物活性化合物的含量在浆果成熟过程中会发生变化。因此，采摘时间的选择是决定蔓越莓原料植物化学成分的因素之一。
