The present invention relates to a method for treating a disorder chosen from ocular Demodex, Demodex-induced blepharitis, rosacea, acne, and meibomian gland dysfunction in a patient in need thereof, comprising administering to the patient a composition comprising a therapeutically effective amount of a substance chosen from at least one of an isoprenoidal essential oil such as Tea Tree Oil; Terpinen-4-ol; Carvone; alpha-Terpineol; Cardinene; d-Carvone; l-Carvone; gamma-Terpinene; alpha-Terpinene; 1,8-Cineole; alpha-Terpineol; para-Cimene; alpha-Pinene; Limonene; (R)-(+)-Limonene; alpha-Thugene; Eucalyptol; (+)-Ledene; Cuminic Aldehyde; and Myrcene; the administration comprising contacting or scrubbing an affected area of skin or hair, or eyelid margin and lashes of the patient with the composition; also disclosed are a method for treating mange and mite infestations on a mammalian animal; and kits for in-office and at home treatments of the disorders.

The invention provides a making method for a Stethynium empoascae Subba Rao attractant. The attractant is formed by combination of tea shoot volatile nerol, n-pentanol, alpha-terpinene and careen six components in certain proportion, and is loaded on a wool felt to make a lure core. The dose of each component is 10<-2>g / mL-10<-6>g / mL, and each lure core contains the six information-substances with a total volume of 100-200 microliters. Usually, during September to November every year, the Empoasca vitis Gothe population in tea garden enter the autumn peak season, and have substantial damage to tea, the dominant natural enemy Stethynium empoascae Subba Rao increases significantly in number, in the full incidence beginning period, a large number of Stethynium empoascae Subba Rao are attracted by the attractant to parasitize Empoasca vitis Gothe eggs so as to greatly enhance the natural parasitic rate, lower the Empoasca vitis Gothe Empoasca vitis Gothe, and reduce chemical control. The attractant does not pollute the environment, has no residue, and is beneficial to protection and utilization of tea garden biodiversity.

A fuel composition is provided that contains (a) a major amount of a mixture of hydrocarbons in the gasoline boiling range and a minor amount of and (b) a minor amount of alpha-terpinene.

A process for purifying monoterpenes, including the steps of: providing a monoterpene comprising alpha terpinene of about 90% or greater purity and comprising an oxygen-containing impurity compound selected from the group consisting of 1,8-cineole, 1,4,-cineole, and mixtures thereof; providing an activated silica gel preparative chromatographic column; contacting the monoterpene with the column, wherein the oxygen-containing impurity compounds are retained on the column; recovering monterpenes depleted of oxygen-containing impurity compounds from the column by applying a pressure above atmospheric from a gas source without the use of a solvent; and removing the oxygen-containing impurity compounds by contacting the column with an alcohol.

The invention discloses a purification method for 1, 8-cineole and particularly discloses a separation and purification method for 1, 8-cineole in low-content raw oil. The method is characterized by comprising the steps of (1) adding raw oil, acetic acid or a water solution of acetic acid and a catalyst into a reaction flask, wherein the raw oil contains 1, 8-cineole and limonene; (2) heating and stirring to react; (3) after the reaction is ended, filtering a reaction solution to recycle the catalyst, and carrying out reduced pressure distillation on an oil phase to obtain 1, 8-cineole with high purity. By using the purification method, the content of 1, 8-cineole in the raw oil can be kept constant after being treated, and the content of limonene as an impurity can be reduced to 0.2-1.1%, so that 1, 8-cineole with high purity can be obtained. Meanwhile, after reacting, limonene in the raw oil generates alpha-terpinene, gamma-terpinene, alpha-terpilenol and the like which all have higher additional values and can not affect the distillation of 1, 8-cineole, therefore, the purification method is a low-cost and green-chemical purification method.

The invention provides a synthesis method of an N-aminoethyl terpinene maleimido imidazole derivative. The synthesis method comprises the following steps: converting alpha-pinene serving as a raw material into alpha-terpinene maleic anhydride adduct (called TMA for short), then reacting the alpha-terpinene maleic anhydride adduct with ethanediamine so as to prepare a midbody, namely N-aminoethyl terpinene maleimide (called ATM for short), and then synthesizing the N-aminoethyl terpinene maleimido imidazole derivative with potential biological activity through modified reaction of amino in the N-aminoethyl terpinene maleimide. The synthesis method has the advantages that the synthesis of the important imidazole ring-containing organic compound by introducing N atoms into the alpha-terpinene maleic anhydride structure is realized for the first time; the N-aminoethyl terpinene maleimido imidazole compound has multiple biological activity, particularly bactericidal activity, the applicant range of the alpha-pinene is widened, and a new approach is supplied for the deep development and utilization of natural organic green resources-turpentine.
