Phytochemical And Biological Activity Studies On Garcinia Atroviridis Griff. Ex T. Anders.
The volatile oil of the fruit of Garcinia atroviridis Griff. ex T. Anders. was isolated by hydrodistillation and analysed by capillary GC and GC-MS, using three columns of different polarity. The oil was dominated by sesquiterpenoids, with the most abundant components being (-)-β-caryophyllene (23.8...

| Summary: | The volatile oil of the fruit of Garcinia atroviridis Griff. ex T. Anders. was isolated by hydrodistillation and analysed by capillary GC and GC-MS, using three columns of different polarity. The oil was dominated by sesquiterpenoids, with the most abundant components being (-)-β-caryophyllene (23.8 %), β-caryophyllene alcohol (15.6 %) and α-humulene (10.7 %). Three of the volatile constituents, β-caryophyllene alcohol (68), ginsenol (70) and (1S,2S,5S,8S)-4,4,8-trimethyltricyclo[6.3.1.01,5]dodecan-2-ol (71) were synthesized and isolated by preparative GC for authentication purposes. |
