Problems solved by technology

Although hexarrhizae is widely known as a Chinese herbal medicine, there is basically no report on the antibacterial activity of hexarrhizae essential oil
[0004] Traditional essential oil extraction methods generally go through steps such as crushing, distillation, condensation, and oil-water separation. Hexarrhizae has its unique structure and composition. In actual operation, the mixture of stems and leaves sticks to the bottom of the reaction vessel after crushing, which delays the process of extraction. The extraction speed of essential oil is increased, the cost is increased, and the yield of essential oil extraction will be reduced

Abstract

The invention provides Blumea laciniata essential oil with antibacterial activity and a preparation method and application thereof. The method includes separating stems and leaves of Blumea laciniatato obtain Blumea laciniata stems and Blumea laciniata leaves; cutting the stems; adding the cut stems and the leaves into NaCl solutions separately to soak the stems and the leaves, heating the mixtures separately and performing steam distillation to obtain a Blumea laciniata stem extract and a Blumea laciniata leaf extract; fully mixing the extracts to obtain the essential oil. The method can avoid an essential oil yield decrease caused by adhesion of Blumea laciniata raw materials onto the bottom of an extraction device in an essential oil preparation process. Through soaking the Blumea laciniata raw materials in the NaCl solutions, oil-water separation in an extraction process for the essential oil is effectively promoted, extraction time is shortened, the cost is reduced, and loss of heat sensitive components in the essential oil is reduced so that the essential oil has good antibacterial activity.

Description

technical field [0001] The invention belongs to the field of plant essential oils, and in particular relates to an antibacterial activity of the six-eared rib essential oil and its preparation method and application. Background technique [0002] Six-eared ribs, also known as Liuerling, Diaozhonghuang, Boyuan Ainaxiang, is a stout herb of the genus Ainaxiang in the Asteraceae family. It is mainly distributed in tropical and subtropical regions. In my country, it is mainly distributed in Guangdong, Yunnan, Guizhou, Guangxi, Fujian and Taiwan and other provinces and regions. Hexarrhizae is often used by local residents as a Chinese herbal medicine. It is mainly used for dredging meridians, activating collaterals, expelling wind and dampness; it is used for snake bites, rheumatic arthralgia, eczema, etc. The whole herb has a unique fragrance and is an important aromatic plant in my country. Its stems and leaves contain essential oils with special aromas. [0003] Plant essenti...
