摘要

该研究测定了在立陶宛自然栖息地采集的蔓越莓小果实样本中黄酮醇、原花青素、花青素、三萜化合物和绿原酸的组成以及蔓越莓果实提取物抗氧化能力的变化。研究结果表明,在蔓越莓果实样本中,黄酮醇类化合物主要是金丝桃苷和杨梅素-3-O-半乳糖苷;花青素类化合物主要是青花素-3-O-半乳糖苷、青花素-3-O-阿拉伯糖苷、芍药苷-3-O-半乳糖苷和芍药苷-3-O-阿拉伯糖苷;三萜类化合物主要是熊果酸。在采普凯利亚伊国家级自然保护区采集的样本中,黄酮醇和花青素的总量最高(分别为 2079.44 ± 102.99 μg/g 和 6993.79 ± 350.22 μg/g)。蔓越莓果实小样本化学成分的聚类分析揭示了蔓越莓果实中生物活性化合物的积累趋势。在立陶宛中部采集的蔓越莓果实样本中,三萜化合物的含量较高。统计相关性分析表明,氰苷-3-O-阿拉伯糖苷和芍药苷-3-O-阿拉伯糖苷的定量组成与 FRAP 法体外评估的蔓越莓果实样品乙醇提取物还原能力之间的相关性最强(分别为 r = 0.882,p < 0.01 和 r = 0.805,p < 0.01)。综上所述,地理因素影响了蔓越莓果实样本中生物活性化合物定量组成的变化。

Determination of Biologically Active Compounds and Antioxidant Capacity In Vitro in Fruit of Small Cranberries (Vaccinium oxycoccos L.) Growing in Natural Habitats in Lithuania
The composition of flavonols, proanthocyanidins, anthocyanins, triterpene compounds, and chlorogenic acid in small cranberry fruit samples collected in natural habitats in Lithuania and variation in the antioxidant capacity of cranberry fruit extracts was determined. This study showed that in the flavonol group, hyperoside and myricetin-3-O-galactoside predominated in cranberry fruit samples; in the anthocyanin group, the predominant compounds were cyanidin-3-O-galactoside, cyanidin-3-O-arabinoside, peonidin-3-O-galactoside, and peonidin-3-O-arabinoside, and in the group of triterpene compounds, ursolic acid was predominant. The highest total amounts of flavonols and anthocyanins were found in the samples collected in Čepkeliai State Strict Nature Reserve (2079.44 ± 102.99 μg/g and 6993.79 ± 350.22 μg/g, respectively). Cluster analysis of the chemical composition of small cranberry fruit samples revealed trends in the accumulation of bioactive compounds in cranberry fruit. Cranberry fruit samples collected in central Lithuania had higher levels of triterpene compounds. Statistical correlation analysis showed the strongest correlation between the quantitative composition of cyanidin-3-O-arabinoside and peonidin-3-O-arabinoside and the reducing capacity of the ethanolic extracts of the cranberry fruit samples assessed in vitro by the FRAP assay (r = 0.882, p < 0.01 and r = 0.805, p < 0.01, respectively). Summarizing the results, the geographical factor affects the variation of the quantitative composition of biologically active compounds in cranberry fruit samples.

期刊介绍: Antioxidants (ISSN 2076-3921), provides an advanced forum for studies related to the science and technology of antioxidants. It publishes research papers, reviews and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
