Abstract: In this study, ultrasonic extraction, molecular sieve separation and single column were used to isolate aromatic compounds from Gynostemma pentaphyllum and mass spectrometry was used for qualitative analysis of the compounds. Three aromatic compounds are determined as docosanoic acid, 1,2,3-propanetriyl ester with molecular formula C66H129O6 and molecular weight 1146, dasycarpidan - 1 - methanol, acetic acid (esters) with molecular formula C20H31N2O2 and molecular weight 331, and 9,12,15-octadecatrienoic acid,2-phenyl-1,3-dioxan-5-yl ester with molecular formula C28H40O4 and molecular weight 440.
