Study of component composition of volatile compound of Bidens tripartita herb
Abstract
The chemical composition of the Bidens tripartita herb has been not studied well. We know that the content of essential oil is 0.11% in the herb but we did not find information about its componential content. Therefore, studying of componential content of volatile substances in the Bidens tripartita herb is actual.
The aim of the work is a study of component composition of volatile compound of Bidens tripartita herb.
The object of the work is the Bidens tripartita herb. The method of the work is chromatography-mass-spectrometry.
We identified and determined the quantitative content of 33 volatile substances in the Bidens tripartita herb. The content of 8-methylnaphtotiophen was the highest and made up 1 057.60 mg/kg or 19% of the sum of volatile substances. In addition to that, a large quantity of the caryophyllenoxide (583.90mg/kg) and humulenoxide (548.20mg/kg) (10% of the sum of volatile substances each) was contained. The content of cis-linalool oxide was the least (3.90mg/kg).
It was established, that the content of 8-methylnaphtotiophen, caryophyllenoxide and humulenoxide dominates in the herb.
