Volatile components of the ginger flower (Hedychium coronarium Koenig) were concentrated by solvent extraction and further simultaneous distillation and extraction (SDE).

The volatile compounds in the headspace of the living orchids Calanthe izu-insularis Ohwi et Satomi (Orchidaceae) and Calanthe sieboldii Decne (Orchidaceae) were examined, after absorption on to Tenax TA, by GC and GCΒ±MS. Sensory analysis showed that in C. izu-insularis linalol and indole provided t
