Abstract
Circaea lutetiana is a medicinal plant in the Onagraceae family. The plant has been used for the treatment of wounds. As its chemical composition possesses valuable components, the infusion has been drunk or washed for treatment of injuries. The paper identified the chemical components of the leaves and stems of the plant Circaea lutetiana. The compositions of Circaea lutetiana leaves and stems were extracted with hexane and analyzed using gas chromatography-mass spectrometry (GC-MS). The method of peak area normalization was used to identify 22 compounds. Among them, The primary compounds (leaves and stems) are esters (30,799%), alkanes (12,69%), fatty acids (carboxylic acids), oxo-fatty acids (7,038%), phytosterols (3,43%), triterpenoids (3,01%). Analysis of each part of the plant (stems, leaves, and fruits) and more detailed information on the specific plants were investigated.
