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 GC–MS. Sensory analysis showed that in C. izu‐insularis linalol and indole provided the fresh daphne and lily‐of‐the‐valley‐like odours, whereas in C. sieboldii methyl benzoate, methyl salicylate, carvone and cinnamic aldehyde contribute to the sweet orange‐like spicy odour. The flowers of C. sieboldii were also extracted with hexane and the extract analysed: 150 compounds were identified. The major component was methyl hexadecanoate (13.5%) but from a sensory point of view aliphatic aldehydes, phenyl methyl ethers and 2‐hydroxypinan‐3‐one were probably more important. © 1997 John Wiley & Sons, Ltd.
