More active compounds in prune juice

More active compounds in prune juice
Another reason why people who have used prune juice for constipation may have had very good reasons to do so, is the discovery of another compound in prunes and prune juice that acts as a chemical laxative.

This compound, called dihydroxyphenyl isatin, reportedly stimulates contraction of the intestinal wall and increases secretion of fluid, making the stools softer.

So the use of prune juice for constipation has a lot of scientific backing.

Prunes and prune juice are also very rich in magnesium.

During a study, USDA researchers yanked magnesium out of prunes and the fruit's laxative properties dropped to almost zero.

But when they fed the purified prune magnesium alone to mice, not much happened either.

It seems that the famous prune chemical works only when it's in the prunes.

Dr. Sydney Marsi, who worked on the study, believes the magnesium is "chelated", or locked together, with other chemicals in prunes that potentiate the laxative effect.
