GC-MS analysis of chemical constituents of the essential oil from Adenosma indianum (Lour.) Merr. by different extraction methods

Xiaoyong Zhu

Abstract

Objective:To analyze the chemical constituents of essential oil from Adenosma indianum (Lour.) Merr..Methods:The essential oils were extracted from Adenosma indianum (Lour.) Merr.by supercritical fluid extraction (SFE) and steam distillation (SD).The amount of the constituents from the essential oil was determined by normalization method,and the constituents separated were identified by GC-MS.Results:There were 57 constituents from Adenosma indianum (Lour.) Merr.by SD that composed of about 92.19% of the total essential oil were separated and identified;There were 39 constituents by SFE that composed of about 70.75% of the total essential oil were separated and identified.Conclusion:The constituents of essential oils extracted by SFE-CO2 were different from that of extraction by SD.The result provided evidence for understanding the constituents of essential oils and explitation of Adenosma indianum (Lour.) Merr..
