title: [T.L.C. separation and capsaicin evaluation in red peppers (author's transl)].
abstract: Capsaicin is extracted from dried powdered pepper by 2-propanol in Soxhlet, separated by TLC on Silica gel, developing with petroleum ether (40-60 degrees C PB), chloroform and acetonitrile (40:45:15) mixture and spectrophotometrically estimated at 280nm. The method appears to be accurate and suitable for routine analysis.
