Volatile Constituents from the Leaves of Zanthoxylum armatum DC., a New Source of 2-Undecanone

Authors : Prashant Singh, Manindra Mohan and Sanjay Gupta

Abstract: The purpose of this study was to evaluate the volatile constituents from the leaves essential oil of Zanthoxylum armatum. The essential oil from fresh leaves of Zanthoxylum armatum obtained by hydro-distillation was analysed by GC/FID and GC/MS. Twenty three components were identified, representing 99.5% of the oil. The major classes of compounds found in the leaves essential oil were non-terpenic acyclic ketones which represented the main fraction with 2-undecanone (65.6%) as the major constituent, making this plant a new and good source of this substance. The present study suggested that the leaves essential oil of Z. armatum collected from Joshimath of the Garhwal region of Uttarakhand Himalaya, India is an outstanding new source of 2-undecanone, a compound highly appreciated in perfumery and flavoring industry as well as due to its strong odor, it is primarily used as insects repellent. Therefore, researchers concluded that leaves essential oil of Z. armatum can be used as a commercial source for the isolation of 2-undecanone and can be commercially exploited as valuable perfumery and flavoring ingredient.
