Identification of chemical compositions in some medicinal plants by GC MS analysis

الملخص EN

Medicinal plants used in treatment of diseases earlier times, are potential sources of new drugs.

In this study, chemical compositions of Echium khuzestanicum, Marrubium anisodan and Echinops cephalotes were identified by Gas Chromatography-Mass Spectrometry (GC/MS).

M.anisodan and E.cephalotes aerial organs andE.khuzistanicum flowers were extracted by maceration method.

According to the results, 46 kinds of chemical compounds found in methanol extract of E.khuzestanicum.

There are mucilage, fatty acids, flavonoid and diterpenes in the flower of E.khuzestanicum.

Seventy six kinds of chemical compounds were found in methanol extract of E.cephalotes including aldehydes (7.9%), phenols (7.5%), fatty acids (5.8%) andfurfural (5.4%) and86 kinds of chemical compounds found in M.anisodan extract.

Furfural, steroids, vitamin B and flavonoids are the main compounds of M.anisodan.
