ヘッドスペース法を用いた新しいフレグランス開発

抄録

Headspace analysis (HSA) is a useful technique to investigate new materials and create new fragrances.
We have selected several fragrant flowers that smell good but hardly or never used for fragrance materials. And using HSA, we have investigated volatile components of that flowers, Hamanasu (Rosa rugosa Thunb.), Freesia (Freesia Hybrida Hort.), Gekkabijin (Epiphyllum oxypetalum Haw.), and Phalaenopsis (Phal. schillerana Rchb. f.).
Particularly about Phalaenopsis, we invesigated changes of main volatile components in day cycle and blooming cycle. About day cycle, it emitted mainly in daytime (from 5 am. to 1 pm.). About blooming cycle, it emitted from the beginning of flowering time, gradually gained as blooming and after full blossom it diminished gradually.
Using that results, we reproduced the smell of that fragrant flower, and produced fragrant products that reminded the smell of them.
About each flower, this paper describes the reasons of our selection, volatile components on HSA and applications for fragrant products.
