Problems solved by technology

According to literature reports, ascaridin, p-cymene and α-terpinene are the main components of the volatile oil of Nepeta nepeta, and they are representative to a certain extent, but the method for simultaneous determination of these three components has not been reported
Volatile oil components are generally selected for analysis by gas chromatography, but gas chromatography adopts capillary columns to affect the stability of its measurement due to factors such as shunting. The invention provides a method for simultaneously measuring ascaridin and paracystin in the volatile oil of Nepeta nepeta with HPLC. HPLC Determination Method of Anthracene and α-Terpinene

Abstract

The invention relates to a method for determining effective component contents in chenopodium ambrosioides volatile oil, and the method comprises the following steps: step 1, preparing a chenopodium ambrosioides volatile oil solution; step 2, injecting into a high performance liquid chromatograph for peak area determination; step 3, calculating the effective component contents in the chenopodium ambrosioides volatile oil.

Description

technical field [0001] The invention relates to a method for the content of active ingredients in traditional Chinese medicine, in particular to a method for measuring the content of active ingredients in the essential oil of Nepeta nepeta. Background technique [0002] Nepeta is the whole herb of Chenopodium ambrosioides L., a plant of Chenopodiaceae. It has the effects of expelling wind, killing insects, and relieving menstrual pain. It is used for skin rheumatic arthralgia, dysmenorrhea, amenorrhea, skin eczema and snake insects bite. According to literature reports, ascaridin, p-cymene and α-terpinene are the main components of the volatile oil of Nepeta nepeta, and they are representative to a certain extent, but the method for simultaneous determination of these three components has not been reported . Volatile oil components are generally selected for analysis by gas chromatography, but gas chromatography adopts capillary columns to affect the stability of its measu...
