Chavicol β- d-glucoside, a phenylpropanoid heteroside, benzyl-β- d-glucoside and glycosidically bound volatiles from subspecies of Cedronella canariensis

Abstract

The volatile substances obtained after enzymatic hydrolysis of purified polar extracts from the aerial parts of the two subspecies of Cedronella canariensis were shown to be, among others, benzyl alcohol (29.4%), chavicol (11.6%), cis-3-hexenol (9.3%), 2-phenylethanol (8.6%), cis-pinocarveol (5.1%), myrtenol (2.2%), 1-phenylethanol (2.0%, tentatively), 1-octen-3-ol (1.8%), 1-hexanol (1.1%) for ssp. canariensis and chavicol (85.1%), benzyl alcohol (2.5%), cis-3-hexenol (2.5%), 1-octen-3-ol (2.3%); 1-hexanol (0.8%) for ssp. anisata. Sugars detected in the polar fraction after hydrolysis were glucose, rhamnose and fructose. The main glycosides obtained from the polar fraction before hydrolysis were chavicol glucoside (6 ppm, ssp. anisata) and benzyl alcohol glucoside (2 ppm, ssp. canariensis).
