The present study focused on evaluating the biochemical profiles of four apricot cultivars (cv.) (Prunus armeniaca L.) grown in Latvia and demonstrating their processing to obtain the food product, dried candied fruit (DCF). The fingerprinting of apricot fruit approached by LC-MS and ultraviolet–visible spectroscopy revealed the abundance of bioactives responsible for the antioxidant activity. The outstanding composition of group compounds, i.e., phenolics, flavonoids, and vitamin C, was observed in the cv. ‘Dimaija’, followed by cv. ‘Gundega’ and cv. ‘Velta’. The lowest values were found in the cv. ‘Boriss’ and fruit from a market of Greek origin. However, the latter two contained the highest carotenoid levels due to a more pronounced maturity. Amongst the 13 individual phenolics detected, rutin, chlorogenic and neochlorogenic acids, catechin, and epicatechin prevailed. The concentrations observed were the highest in cv. ‘Dimaija’, followed by cv. ‘Velta’ and cv. ‘Gundega’. Osmotic dehydration and convective drying of apricot fruit variedly influenced the content of bioactives in DCF products. The most substantial decrease due to thermal lability was observed in the vitamin C content in DCF, accounting for a 95.3% loss for all cultivars. The content of total phenolics, flavonoids, and carotenoids in DCF, on average, was 62.7%, 49.6%, and 87.6% lower than that observed in the raw fruit, respectively. On average, the content of individual phenolics in DCF, such as rutin and chlorogenic acid, decreased by 63.8% and 20.8%, respectively. The decline in the content of bioactives was conditioned by the physical migration of the cell components to the hypertonic solution. However, the increase in the content of cell wall-bound phytochemicals, such as catechin and epicatechin, after osmotic dehydration and convective drying, was observed in DCF, corresponding to a 59.5% and 255.64% increase compared with the raw fruit, respectively. Panelists generally responded positively to the developed DCF; however, greater preference was given to products with a lower phenolic content, such as cv. ‘Boriss’ and those produced from the market fruit. It is believed that the high flavan-3-ols content, along with chlorogenic acid, contributed to the bitter taste of DCF. Overall, apricot fruits represent the abundance of bioactives retained in DCF after osmotic dehydration and convective drying. The findings observed in the current study allow to consider DCF as a functional food; however, given the high sugar content, their consumption should be in moderation.

“…The determination of the total flavonoid content in the ethanolic extract of the aerial parts involved using the aluminum trichloride (AlCl3) method [20].The quantification of total flavonoids followed a method described by Hayat et al [21], with minor modifications. Specifically, 2 mL of both the extract and standard were combined with 0.1 mL of AlCl3 solution (10%) (m/v), 0.1 mL of sodium acetate (1 M), and 2.8 mL of distilled water.…”

This study aims to thoroughly examine the chemicals and effects of the ethanol extract from T. polium’s upper parts. We used the Soxhlet method for extraction, resulting in an extract with a significant yield of 20.6%. Qualitative analysis identified a variety of compounds, such as tannins, saponins, reducing compounds, terpenoids, quinones, and alkaloids. In quantitative analysis using the colorimetric method, we found the extract was rich in total flavonoids (20.78 mg equivalent QE/g DW extract) and total polyphenols (227.43 mg equivalent GAE/g DW extract). To assess antioxidant potential, we used the ferric reducing antioxidant power (FRAP) method, with ascorbic acid and butylated hydroxytoluene (BHT) as standards. The extract showed moderate activity in both the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and FRAP methods at concentrations of 65 µg/mL and 21 mg/mL, respectively. Additionally, we tested the ethanolic extract against various bacteria using the disk diffusion technique on agar medium. The results indicated that the T. polium extract had moderate effectiveness against Gram-negative bacteria like Pseudomonas aeruginosa ATCC 9027 and Escherichia coli ATCC 8739, as well as Gram-positive bacteria like Staphylococcus aureus ATCC 6538 and Bacillus subtilis ATCC 6633. We further investigated the composition of the ethanolic extract through LC-MS/MS analysis, establishing a detailed profile of phenolic compounds, with six flavonoids identified as the main polyphenolic constituents. This thorough evaluation provides insights into the potential therapeutic uses of T. polium.

“…Apricot peels also have higher procyanidin, hydroxycinnamic acid, and flavonols content than apricot pulp [56]. Fresh apricot fruits contain high amounts of polyphenols (165.49 mg of GAE/100 g DM) and flavonoids (12.11 mg QE/100 g DM) [57]. Catechin, quercetin-rutinoside, and quercetin-rhamnoside have been identified in plums via RP-UHPLC [58].…”

Research-Gap-Spotting in Plum–Apricot Hybrids—Bioactive Compounds, Antioxidant Activities, and Health Beneficial Properties

Plum–apricot hybrids are successful backcrosses of plums and apricots resulting in plumcots, pluots, and apriums. A topic search on plums, apricots, and plumcots shows that extensive information exists on the agro-morphology, genotyping, bioactive substances, and nutritive value of the genus Prunus, and plums and apricots, in particular. However, when search results for plum–apricot hybrids were evaluated for the period 2010–2023, only a few papers focused partially on the topic of their metabolomics. A database search (Scopus, PubMed, and Google Scholar) exposed that less than 10 articles/year appeared in Scopus on the topic of plum–apricot hybrids, 618 papers were found on Google Scholar (2010–2023), and only 2 results were found in PubMed for the same period using the same keywords. This shows the grand research opportunity and the need for providing a thorough chemical characterization of the existing plum–apricot hybrids. This review aims at schematizing the available information about plum–apricot hybrids (with reference to their parents), identifying the gaps about their bioactive compounds, antioxidant activities, and health beneficial properties, as well as pointing to future perspectives in terms of fruit hybrid characterization.
