JPH119092A - Production of plant in which active ingredient for eliminating active oxygen species is increased - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a method for producing a plant havign a function increased in an active ingredient for eliminating active oxygen species by irradiating the plant such as a vegetable, fruit, alga, herb or three with light containing UV light having a specific wavelength or strength during the growth of the plant or after the harvest of the plant. SOLUTION: During the growth of a plant or after the harvest of the plant, the plant is irradiated with light containing artificial UV light. When parsley is cultured in a green house, the parsley is irradiated with UV light-containing light for one hr or longer in each day during a week before the harvest of the parsley. After the irradiation, the parsley is analyzed. The analysis result shows than an active ingredient for eliminating active oxygen species is increased in comparison with that of non-irradiated parsley.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is to produce or produce plants having a function of increasing active components for eliminating active oxygen species.

[0002]

2. Description of the Related Art Sunlight is indispensable for the production or growth of plants from the beginning. However, not only plants in the natural world but also active components for erasing active oxygen species are exposed to the ultraviolet rays contained in the sunlight.・ Although differences in distribution areas are included, vinyl cultivation and the like produce vinyl by absorbing ultraviolet rays and reducing the active components that eliminate the active oxygen species inherent in plants.

[0003]

SUMMARY OF THE INVENTION The object of the present invention is to harvest and produce plants having a function of increasing active components for eliminating active oxygen species.

[0004]

Means for Solving the Problems Now, the manufacturing method is described as follows. (A) In the growth stage of plants, the plants are irradiated with ultraviolet rays containing a specific wavelength and intensity. (B) After harvesting the plants, the plants are irradiated with an ultraviolet ray containing a specific wavelength and intensity.

[0005]

Embodiment (1) The embodiment of the present invention is as follows. In the greenhouse cultivated parsley, for one week before harvesting, irradiate with ultraviolet ray containing light for 1 hour or more during the day during the day. Obtain parsley with increased ingredients.

[0006]

[Example (2)] 1 before harvest in parsley of normal cultivation
During the week, ultraviolet rays containing light are irradiated for one hour or more during the day during the day, and the post-irradiation analysis results in parsley containing more active components than those not irradiated with the active oxygen scavenging active component.

[0007]

Example (3) After harvesting the parsley produced normally, the parsley is irradiated with a light ray containing ultraviolet rays for 5 minutes or more.
Get more parsley.

[0008]

As described above, a plant obtained by irradiating a plant with a light beam containing ultraviolet rays has an increased active component for elimination of reactive oxygen species, so that a plant more than the component originally possessed by the plant can be obtained.
As an even greater effect, eating plants that have been exposed to UV light will be useful for health.

Claims (1)

[Claims] (1) Irradiation with ultraviolet rays is carried out during the growth and cultivation of vegetables, fruits, algae, medicinal plants and trees, or after harvesting. A method for producing plants, fruits, algae, medicinal plants, and trees having an increased active oxygen species-eliminating active ingredient, comprising the steps described above.
