GC-MS Analysis of the Volatile Oils from Anisochilus carnosus (L.) Wall
The volatile oils were extracted from Anisochilus carnosus(L.) Wall by means of steam distillation.By using GC-MS techniques,referring to the search of standard spectrum and calculating the relative contents of the chemical compositions with the method of ionic peak area,twenty-six compounds were identified from the oils of leaves and stems,accounting for 98.7% of the total volatile oils,twenty-one compounds were identified from the oils of roots,accounting for 91.24% of the total volatile oils for the first time.The major compounds were alkene,alcohol,ester,ketone,and hydroxybenzene.The major constituents were both α-cyperolone(44.48% and 36.85%),carvacrol(18.47% and 27.82%),zierone(6.69% and 6.31%).
