PROBLEM TO BE SOLVED: To provide a new and useful method, by which a polymethoxyflavonoid can be recovered from a citrus in a relative high purity and in a relative short time in stead of a conventional ethanol extraction treatment method. SOLUTION: The method for recovering the polymethoxyflavonoid such as Nobiletin or Sudachitin from the pericarp of a citrus includes contacting the pericarp of the citrus with 140 to 180°C semi-critical water for a time of ≤5 minutes to extract the polymethoxyflavonoid in the semi-critical water. It has been ascertained that all the total amount of the extract, the total amount of an ether extract extracted with diethyl ether, and the extract amounts of the Nobiletin and the Sudachitin by the semi-critical water extraction treatment are larger than those by the conventional ethanol extraction treatment.

PROBLEM TO BE SOLVED: To provide a way for effective utilization of a compound produced in a disposal process of waste plastics and to provide a new and useful plant growth promoter. SOLUTION: The plant growth promoter comprises 3-(3-tertiary butyl-4-hydroxyphenyl)-propionic acid, 3-(4-hydroxyphenyl)-propionic acid or 3-(3-benzoyl-4-hydroxyphenyl)-propionic acid as an effective ingredient. 3-(3-Tertiary butyl-4-hydroxyphenyl)-propionic acid can be produced by a treatment, with subcritical water, of a benzotriazole compound contained in a plastic product as an ultraviolet absorber.

PROBLEM TO BE SOLVED: To provide a method for easily intensifying carotenoid pigments such as β-cryptoxanthin without accompanying physical change of citrus.SOLUTION: Contents of carotenoids such as β-cryptoxanthin contained in citrus are increased by irradiating the citrus with red light or far infrared light under a metabolizable environment. Preferably, the citrus is irradiated with the light emitted from LEDs. By simultaneously utilizing ethylene treatment, the total contents of carotenoids are securely increased and the red color is intensified. As a result, the color tone of the citrus can be made to look more delicious, and further, the content of β-cryptoxanthin can be synergistically increased.
