Specificities of purified extracts in comparison with crude extracts

.
Myth 1 : Regarding pine, all species are the same: False!
There are many different types of pine trees, for model :

• The pinus pinaster or maritime pine, found in the forests of Les Landes. Note that this is the only species found in Les Landes: an extract of native Landes pine is 100% pinus pinaster, and is therefore, fully traceable.
• The pinus radiata, very present in New Zealand
• The pinus massoniana, mainly found in China

The bark extracts all control polyphenols, but their typography is identical different depending on the species :
. Pinus pinaster/Pinus Massoniana HPLC analysis comparative
Maritime pine bark has a specific composition, different from other species of pine..
. Myth 2 : Crude extract of pine bark contains the same amount of polyphenols as purified extract, so it’s the same thing! False!
In the event of crude extract, compared with that of purify extract, the polyphenol content is efficaciously identical ( generally > 96 % ) .
Pinus pinaster bark extracts basically contain :

• proanthocyanidins (or procyanidins)
• polymers of cathechine or epicathechine

Oligopin® and Cosmythic®, ache bark extracts from Les Landes, when highly purified, contain a minimal of 67 % OPC .
Crude extracts consist chiefly of high gear molecular weight polymers ( tannins ), while the purify extracts are concentrated in low weight polymers or oligomers ( OPC ) .
It is the latter ( the OPCs ), which are responsible for the beneficial effects .
The results of the chemical dose, found on the analysis certificates of assorted pine bark extract providers, does not distinguish OPC tannins ( the Folin test is used to determine polyphenol content, the Bate-Smith screen is used to determine procyanidin content and the ORAC test is used to determine antioxidant capacity ) .
only more speciate methods enable the analysis of the procyanidins based on their molecular system of weights : namely, the thiolysis method acting, which is rarely used, because it is difficult to implement, or GPC ( Gel Permeation Chromatography ) .

Please feel absolve to compare the different products with good analytic methods ! *
. Myth 3 : A crude extract is ‘closer to nature’ than a purified extract. False!

This affirmation wholly obscures the fact that, since the beginning of time, man has constantly made selective extractions, starting with apples picked from trees, berries picked from bushes or potatoes, without their tops !
Purifying a product does not destroy its nature : in the case of pine bark extract ( Oligopin® and Cosmythic® ), the diverse purification steps used, help to preserve the elements that are best for the human body .
. Myth 4 : A purified extract is much more expensive than a crude extract. False!
It is absolutely normal that the comparison of the price per kilogram favours crude extracts. One must be very careful with this type of affirmation .
In the case of nautical pine extract, the origin succumb is 50 times lower for a purify extract, than for a petroleum extract, rich people in OPC. The origin process is more complex and more expensive to implement
The price comparison relating to the rate of the active ingredient (OPC), favours the purified extract.
Do the maths yourself !
