Abstract: The present disclosure is directed to a method for producing an olive branch extract having a high oleuropein content. The method includes crushing at least a portion of dried olive branch and extracting olive branch extract from the crushed olive branch with an extraction solvent. The olive variety is at least one selected from Lucca, Mission, and Nevadillo Blanco. The added branch amount of olive branch to the extraction solvent is 10% by weight or more, the extraction solvent is 30% to 50% 1,3-butylene glycol, and the extraction is performed at a temperature in a range of 70° C. to 80° C.

Abstract: The present invention provides a method of producing an olive leaf extract that contains a high concentration of oleuropein. A method of producing an olive leaf extract comprises a first step of grinding dried olive leaves and a second step of mixing grapes with the ground olive leaves and then extracting an olive leaf extract using an extraction solvent. In the second step, the extraction solvent is water, alcohol, or a combination thereof, and extraction is performed at 70° C. or higher.

Abstract: A new ultraviolet blocking agent and a cosmetic product having a high ultraviolet blocking action. The inventors have found that the extract obtained from branches of olive has a high effect of absorbing ultraviolet, in particular UV-A and UV-B and has a high ultraviolet absorbing action, and completed. The ultraviolet blocking agent contains an extract of branches of olive. The branches of olive may be bark of olive. The ultraviolet blocking agent may be in the form of a cosmetic product.

Abstract: A road excavator is a drivable vehicle equipped with an excavating apparatus which has a rotary cutter for excavating a paved highway surface, first and second conveyors for exporting an excavated material outside of the excavator, a collector which is placed between the cutter and the first conveyor for gathering the material as much as possible. The collector has a casing having a discharge port at the center thereof for receiving the excavated material and a helical screw, incorporated within the casing, having two sets of spiral blades for gathering the excavated material toward a discharge port and expellers for expelling the material forcibly to the first conveyor through the opening according to the rotation of the screw.
