“…The object of the research was samples of different cultivars of large cranberries ( Vaccinium macrocarpon Aiton) grown in the climatic conditions of Latvia, in the collection of the National Botanic Garden (Salaspils, Latvia) (56°51′55.4″ N 24°21′36.9″ E). The climate in Latvia is temperate and transitional from maritime to continental [ 61 ]. The average yearly temperature is 6.8 °C [ 62 ].…”

In this study, we conducted a qualitative and quantitative analysis of anthocyanins, proanthocyanidins, flavonols and triterpenoids in samples of introduced and bred large cranberry fruits from the collection of the National Botanic Garden of Latvia. The highest total anthocyanin levels (8638–9316 µg/g) were detected in the fruit samples of the cranberry cultivars ‘Black Veil’, ‘Franclin’ and ‘Early Black’. The highest total proanthocyanidin levels (2775–3389 µg/g) were found in cranberries of cultivars ‘Kalnciema Agrā’, ‘Kalnciema Tumšā’, ‘Searles’, ‘Howes’, and ‘Kalnciema Ražīgā’. The highest levels of flavonol compounds (1373–1402 µg/g) were detected in cranberries of cultivars ‘Howes’, ‘Black Veil’ and ‘Salaspils Melnās’. The highest levels of triterpenoids (5292–5792 µg/g) were determined in cranberries of cultivars ‘Kalnciema Agrā’, ‘Septembra’, ‘Džbrūklene’ and ‘Early Black’. The results of our study allow for the estimation of differences in the content of secondary metabolites in the fruit samples of the studied cranberry cultivars and for the selection of promising cultivars for further introduction and cultivation in the climatic conditions of the Baltic countries. These results are also important for the selection of the most promising cranberry cultivars for the preparation of cranberry raw material, and the high-quality composition of plant material ensures the effectiveness of cranberry supplements and other cranberry preparations.

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.
