Abstract: Process for purifying 3,4-dihydroxyphenylglycol (DHPG) from any part of the plant, from the products or by-products derived from olive trees or any other vegetable product of the families Oleaceae, Orobanchaceae, Plantaginaceae, Compositae, Lamiaceae, Acanthaceae and/or Scrophulariaceae, and which comprises 1 or more steps wherein the initial product is introduced into at least one ion-exchange resin column, and in potentially subsequent steps the product eluted in the preceding column is introduced into an ion-exchange resin and/or a non-ionic adsorption resin column. Moreover, it relates to the DHPG extract obtainable by means of the process disclosed and to the applications thereof.

Abstract: The present invention relates to a method for obtaining purified hydroxytyrosol from products and by-products derived from the olive tree by means of two-step chromatographic treatment. The invention uses a non-activated ion exchange resin chromatographic method, followed by a second treatment on an XAD-type absorbent non-ionic resin which concentrates and completely purifies the hydroxytyrosol by means of elution with a methanol or ethanol:water dissolution (from 30 to 33%). The method of the invention can also be applied to two-phase pomaces, three-phase pomaces and stones if they are subjected to a steam explosion process.

Abstract: A porpoise evacuation vessel comprises a skiff-like boat having a central bay area for the temporary retention of porpoises evacuated from tuna fishing nets, there being ramps on opposite sides of the boat leading into the water and open faced wells on opposite sides of each ramp for retaining operators to haul porpoises out of the water and into the bay, subsequent to which the boat, which is jet-propelled, is driven outside the net and the porpoises are released into the open ocean by releasing a rear gate.

Abstract: An adjustable aerosol can holder which securely engages a can by its upper rim and bottom and has a trigger-operated actuator for depressing the firing head of the can to fire same.
