A simple solid injection device for the analyses of Bulbophyllum (Orchidaceae) volatiles

摘要: Abstract The volatile components of three orchid species ( Bulbophyllum weddellii , B. ipanemense and involutum ) were detected using GC/MS. Due to the minute dimension amount flowers, special traps extraction methods applied analyses finally successful a solid sample injector which was constructed in our own laboratory. chemical composition comparison revealed high similarity between volatiles present is coherent with pollinator sharing. On other hand, pollinated by species, are different from two previous species.
