In the mid 1800s Chinese porcelain was transported by train in the United States. The materials used to pack these delicate objects were Paulownia seed pods. Each pod contains up to 2000 small-winged seeds and resembles a giant pistachio nut. Some seeds escaped during transit while others were released at their destination and carried by the wind. It is likely that Chinese porcelain making its way down the New York Central Railroad is responsible for the Paulownia trees along the Metro North Hudson Line.

Givaudan's Roman Kaiser analyzed the scent of Paulownia tomentosa flowers in 1995. When Glass Petal Smoke asked him if there was a little heliotropin in the mix Kaiser responded with scientific precision, “This heliotropin related note is mainly generated by the interaction of the main constituent hydroquinone dimethyl ether with beta-ionone including derivatives and methyl cinnamate. Methyl benzoate, methyl salicylate and methyl 2-methoxybenzoate round this accord off.” Heliotropin is a molecule found in vanilla and smells floral, vanillic, and slightly almond-like (there is a lot of heliotropin in Tahitian vanilla beans). Kaiser’s complete analysis of Paulownia tomentosa is as follows:
Methyl 2-Methybutyrate 0.10
Methyl Caproate 0.10
(E)-Ocimene 0.60
6-Methyl-5-Hepten-2-One 0.30
Nonanal 0.05
Benzaldehyde 0.05
Linalool 0.05
Cyclic-Beta-Ionone 0.10
Methyl Benzoate 5.50
(E)-Beta-Farnesene 0.20
Hydroquinone Dimethyl Ether 79.00
Methyl Salicylate 1.90
Dihyro-Beta-Ionone 1.20
Benzyl Alcohol 0.80
Beta-Ionone 6.00
Methyl- (E)-Cinnamate 0.90
Methyl2-Methoxybenzoate 2.70
Benzyl Benzoate 0.10
Total: 99.65

Some of the fragrance ingredients in Roman Kaiser's analysis of Paulownia tomentosa can be found on Givaudan's website by clicking here. You can cut and paste the name of the molecule to research it. The Good Scents Company has an extensive database of raw materials. Perhaps we will see this kind of organoleptic information democratized in Wolfram/Alpha as the new search engine develops its très cool chemistry section.
Analysis of fragrance molecules is conducted by gas chromatography-mass spectrometry (also known as "GC mass spec" in the fragrance business). The machine analyzes scent, but requires the technical and olfactive skills of a trained professional for optimal results.
