Abstract:
OBJECTIVE:To analyze volatile oil from the roots and fruits of Kadsura longipedunculata. METHODS:GC-MS method was adopted. The determination was performed on HP-5MS quartz capillary column with nitrogen as carrier gas at the flow rate of 0.9 mL/min. The temperature of sample inlet was 250 ℃,the initial temperature of column was set at 50 ℃(temperature programming). The column pressure was 80 kPa;the ratio of split sampling was 40 : 1. The sample size was 1.0 μL. Mass chroma-tography was as follows:electron bombardment ion source as ion source;electron energy of 70 eV;inlet temperature was 230 ℃;scanning range of m/z 40-400,scanning interval time of 1.0 s. RESULTS:Totally 43 chromatographic peaks were detected in vola-tile oil from the roots of K. longipedunculata,and 24 peaks were identified,accounting for 91.5%;main components were sesqui-terpenes and monoterpenoids,among which the relative contents of (+)-delta-cadinene,γ-cadinene and isovalencene were in high level. Totally 52 chromatographic peaks were detected in volatile oil from the fruits of K. longipedunculata,and 36 peaks were iden-tified,accounting for 82.2%;main components were sesquiterpenes and monoterpenoids,among which relative contents of caroph-yllene,γ-cadinene and valencene were in high level. CONCLUSIONS:The study basically confirm main volatile components in volatile oil from the roots and fruits of K. longipedunculata,and the roots and fruits of K. longipedunculata have significant differ-ence.
