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 chromatography 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 volatile oil from the roots of K. longipedunculata, and 24 peaks were identified, accounting for 91.5%; main components were sesquiterpenes 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 identified, accounting for 82.2%; main components were sesquiterpenes and monoterpenoids, among which relative contents of carophyllene, 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 difference.
