Blueberry extract

Hyperoxia (48-hr exposure to >99% 02) decreased TAC of rat lung homogenates (cytosol fraction) by 26%. TAC of the acid-soluble fraction was even more depressed (by 40%). Feeding rats before the experiment with vitamin E-rich diet (500 IU/kg of vitamin E acetate) or diet containing blueberry extract (2.5%) but not spinach extract (0.85%) attenuated this effect of hyperoxic exposure (C14). 

It could be clearly shown that pectinases increase the total content of anthocyanins in blueberry extracts up to 41% higher and in blackcurrant extracts up to 29%. On the other hand, a survey conducted for the enzyme preparation Econase CE showed a negative impact on the total content of anthocyanins extracted from blueberries, whereas no effect could be determined in black currant [117, 121].

The thiocyanate method involves measurement of the peroxide value using linoleic acid as substrate and has also been widely used to measure the antioxidant activity in plant-based foods such as ginger extracts (Kikuzaki and Nakatani 1993), fruit peels (Larrauri and others 1996 1997), extracts from vegetable by-products (Larrosa and others 2002 Llorach and others 2003 Abas and others 2006 Peschel and others 2006), blueberry juice, wines, and vinegars (Su and Chien 2007). 

Coupled GC-EAD of both gland extracts and effluvial collections from female blueberry leafminer, Caloptilia porphyrectica Braun (Lepidoptera Gracillariidae), showed that females produce a single EAD-active compound. (A)-l 1 -hexadecenal was determined to be the sex pheromone based on comparison of the retention time of an authentic standard on both polar and non-polar capillary columns. Microreaction-GC-EAD analyses and field trapping results confirmed the identification. ... 

But my discussion of rat acrobatics isn t intended to turn people into blueberry-guzzling fiends. Eating blueberries won t save you dietary sinners. What matters most is the overall diet composition. In the rat study strawberry and spinach extract also produced improvements in memory, although those foods didn t have the same effect on balance and coordination as blueberries did. Still, the message is that fruits and vegetables have antiaging properties. As we are now learning, they harbor all kinds of useful chemicals. Like the B vitamin commonly known as folic acid. 

For phenolic acids in bilberry juice, a reversed-phase HPLC method (16) using a linear-gradient elution of (a) 2% aqueous acetic acid and (b) acidified, aqueous acetonitrile on two Cl8 columns was able to separate the 12 phenolic acids and flavonoids (three flavonol glycosides and three flavonols) in ethyl acetate extract. Phenolics in blueberries were extracted, isolated, and...

A systematic approach for optimizing the extraction and identification of anthocyanins from blueberries was explored using HPLC-UV and HPLC-ESI-IT-TOF-MS (Barnes et al., 2009). A method was developed for anthocyanin identification without the use of standards. Consideration was given to elution order by chromatographic separation with selective detection at 520 nm, high mass accuracy m/z values, tandem MS fragmentation, and previously published literature. Overall, 25 anthocyanins from a wild type highbush blueberry were identified and reported (Barnes et al., 2009).
