Summary

Methyl salicylate is a naturally occurring compound in black tea. A method has been developed for the determination of the methyl salicylate in tea samples. The method consists of hot extraction of the teas withn-hexane, distilling off the solvent and steam distillation of the resinous mass to obtain the volatile oil. This oil was analysed gas chromatographically using suitable standards. The effect of methyl salicylate on the overall flavour quality is also reported.

Zusammenfassung

Methylsalicylat ist ein natürlicher Bestandteil in schwarzem Tee; für dessen Bestimmung wurde eine Methode ausgearbeitet. Sie beruht auf der Extraktion der Teeblätter mit heißemn-Hexan; das Lösungsmittel wird dann abdestilliert und der harzartige Rückstand einer Wasserdampfdestillation unterzogen, um das flüchtige Öl zu gewinnen. Dieses wird gaschromatographisch unter Verwendung geeigneter Standardproben analysiert. Der Einfluß von Methylsalicylat auf das Aroma wurde besprochen.
