文摘

A new sesquiterpene glycoside, (?-epi-¦Á-bisabolol 6-deoxy-¦Â-d-gulopyranodide (dFont"">1), has been isolated from the glandular trichome exudate of Brillantaisia owariensis (Acanthaceae). The structure of compound dFont"">1 was determined by spectroscopic analysis as well as acidic hydrolysis of 1 leading to (?-epi-¦Á-bisabolol (dFont"">2) and 6-deoxy-d-gulose (dFont"">3). This is the first study to analyze secondary metabolites from glandular trichome exudates of plants belonging to the Acanthaceae family. 6-Deoxygulopyranoside is the first example of an epi-¦Á-bisabolol glycoside of plant origin.
