Bioactive compound of blueberry

Blueberries belong to the genus Vaccinium, which includes more than 450 plants grown in all parts of the world. Members of the Vaccinium genus possessing the darkest-colored fruits appear to provide the greatest health benefits, a fact that scientists attribute to the compounds that give the plants their dark pigmentation.

Generally, blueberries in a fresh form consist of water (84%), carbohydrates (9.7%), proteins (0.6%) and fat (0.4%). The average energetic value of a 100-g serving of fresh blueberries is estimated at 192 kJ. Blueberries are also a good source of dietary fiber that constitutes 3%–3.5% of fruit weight.

Epidemiological studies have shown evidence that the consumption of these fruits is linked to the prevention of chronic non-transmissible diseases, mainly due to the presence of bioactive phytochemical compounds such as phenolic acids, flavonoids and carotenoids.

The total content of polyphenols in blueberries ranges from 48 up to 304 mg/100 g of fresh fruit weight (up to 0.3%) and strictly depends on the cultivar, growing conditions and maturity, and its estimation may vary depending on the analytical procedure used.

Polyphenols present in blueberries include, i.e., flavonoids, procyanidins (monomeric and oligomeric form), flavonols (i.e., kaempferol, quercetin, myricetin) phenolic acids (mainly hydroxycinnamic acids) and derivatives of stilbenes.

Phenolic compounds in the blueberry can be classified into two major groups: non-flavonoids and flavonoids. Flavonoids with a 15-carbon skeleton arranged in a common basic chemical structure, with two aromatic rings linked by a chain of three carbons, form a C6-C3-C6 system.

Non flavonoids, phenolic or simple acids ,are characterized by having a benzene ring, a carboxylic acid grouping ,and one or more hydroxyl groups and / or methoxyl in the molecule.

Antioxidants in apple juice

Apple juice and apple flavoring do appear to be rising in popularity with a noticeable increase in apple drinks appearing on the EU markets. The consumption of apples contributes to reduced risk of disease such as cardiovascular disease and some forms of cancer.

Apple juices are important source of polyphenolic compounds, correlated with antioxidant activities.

Apples and apple juices showed antioxidant activities when tested both in vitro and in vivo; the effects have been attributed to the polyphenolic constituents, such as flavan-3-ols, including monomeric (catechins) and polymeric (procyanidins), hydroxycinamics acids, dihydrochalcones, flavonols and anthocyanins.

The total phenolic content in apple juice was in a range of 0.02 – 0.1% of juice. Catechin and procyanidins are a major class of apple phenolics, representing more than 80% of the total content.

In apple juice, vitamin C activity represented a minor fraction of the total antioxidant activity, with chlorogenic acid and phloretin glycosides as the major identifiable antioxidants.

In epidemiological research some specific flavonoids are associated with protection against ageing diseases.

This might due to their action as antioxidant. Free radicals may attack biomolecules (lipids, proteins, DNA) which can be prevented by antioxidants.

In one study, pure fruit juice, including apple juice inhibited reactive oxygen species generation for up to 90 min after their consumption by 10 healthy young men (J. Med Food.2005;8[1]:41-46).

In addition, 600g of whole apples also acutely reduced oxidative stress levels in six healthy male volunteers.
