Abstract

Anisaldehyde and crotonaldehyde have been tested as spray reagents for the visualization of major components of sesame oil unsaponifiable matter. Colours produced using anisaldehyde were shades of the spectrum, which are characteristic of the lignans and sterols inherented in the Sesamum indicum in relatively higher coverage, sensitivity and selectivity. However, crotonaldehyde could detect four of the eleven unsaponifiable matters in relatively more stable and bright colour spots.
