Constituents of the essential oil from the fruits ofZanthoxylum rhetsoides Drake from Vietnam and from the aerial parts ofZanthoxylum alatum Roxb. from India

Abstract

The essential oil from the fruits of Zanthoxylum rhetsoides Drake (syn. Z. myriacanthum Wall. ex Hook. f.) of north-west Vietnamese origin consists of 78% of monoterpene hydrocarbons, 19% of oxygenated monoterpenes, 1% of n-alcohols and only 1% of sesquiterpenes. The essential oil from aerial parts of Zanthoxylum alatum Roxb. (syn. Z. armatum DC., Z. planispinium Sieb. et Zucc.) collected in north-west India contains 33% of monoterpene hydrocarbons. The main constituents are 1,8-cineole (15.7%, 18), linalol (18.8%, 28) and undecan-2-one (17.0%, 60). Copyright © 1999 John Wiley & Sons, Ltd.
