Peak Areas

A gas chromatography-mass spectrometry (GC-MS) method was developed for analyses of volatile and semivolatile components in Marsdeniae tenocissimae. The volatile and semivolatile components in stem of Marsdenia tenocissima are extracted by soxhlet extraction method with chloroform. The results show that 46 compositions were identified and accounted for 90.144% of the total peak areas. The major volatile and semivolatile components of stem were: alkanes (12.168%), alcohol (6.732%), aldehydes and ketones (7.272%), fatty acids (46.152%), Esters (13.068%), other (4.752%), respectively. The study provides useful data for further analysis of components of Marsdenia tenocissima.
