Abstract

The invention discloses a microwave extraction method for dryopteris fragrans(L.)schott essential oil. The optimum microwave extraction process is selected by controlling the sizes and water content of particles of dryopteris fragrans(L.)schott powder, the microwave intensity is set to be 100 to 500W, the extraction time is 10 to 50 minutes, and the high-quality dryopteris fragrans(L.)schott essential oil can be obtained. The method is easy to operate, and low in production cost; and the prepared product is high in activity and yield. The dryopteris fragrans(L.)schott essential oil prepared by the method has golden yellow color; and cosmetics which are prepared from extractive have the effect of resisting corynebaterium acnes and an obvious anti-aging effect.

Description

technical field [0001] The invention relates to a process for extracting the essential oil of Trichophyllum citrifolia, in particular to a microwave extraction method. Background technique [0002] Dryopteris fragrans (L.) Schott] belongs to the genus Dryopteris fragrans (L.) Schott. It is a rare wild medicinal plant resource with great development potential and application prospects. It can treat stubborn skin diseases such as psoriasis and adolescent acne. It has a good therapeutic effect and is regarded as "the nemesis of skin diseases". In recent years, pharmacological studies have found that D. citrifolia has good anti-oxidation and antibacterial effects. [0003] Essential oil is a kind of important bioactive substances in Trichofern, because of its good anti-oxidation and antibacterial activity, it can be developed into corresponding medicines, or used as additives in cosmetics and food and other industries. Yet still do not have the extracting method of the essent...
