Abstract

The invention discloses a method for continuous preparation of tea tree oil and melaleuca flavone. The method comprises the following steps: with fresh branches and leaves of 4-terpilenol melaleuca asa raw material, conducting distilling by virtue of a redistillation method, and separating the tea tree oil from distillate by virtue of an oil-water separator; and then, conducting secondary extraction on a water extract, implementing filtering, conducting rotary evaporation on a filtrate so as to obtain a concentrated solution which is 30-50% in solid content, and drying the concentrated solution by virtue of a spray-drying tower, so that a coarse melaleuca flavone product that a flavone content is greater than 18% is obtained. The method provided by the invention is low in cost, energy-saving and environment-friendly and simple in process, the method is applicable to large-scale production and the method has good economic and social benefits; and with the application of the method, thetea tree oil, which conforms to international standard ISO4730 and the coarse melaleuca flavone product that the flavone content is greater than 18%, which is capable of boosting body immunity, can be obtained.

Description

technical field [0001] The invention relates to the technical field of plant resource extraction, in particular to a method for continuously preparing tea tree oil and melaleuca flavonoids. Background technique [0002] Tea tree oil is an essential oil obtained by steam distillation of leaves and twigs of Myrlaceaca Melaleuca (Melaleuca) evergreen shrub to small tree Melaleuca native to eastern Australia. The main components are 4- Terpineol. It has obvious broad-spectrum bactericidal and antibacterial effects, and is widely used in pharmaceutical, daily chemical, food, spice and other industries. After tea tree oil is extracted, a large amount of foliage waste is formed, which is not fully utilized. Leaf waste contains flavonoids, which can help the body improve blood circulation, lower cholesterol, improve immunity, enhance wound healing and relieve pain. Therefore, the development of a method for extracting the active components of Melaleuca mellifera branches and leav...
