摘要

A new sesquiterpene glycoside, (鈭?-epi-伪-bisabolol 6-deoxy-尾-d-gulopyranodide (1), has been isolated from the glandular trichome exudate of Brillantaisia owariensis (Acanthaceae). The structure of compound 1 was determined by spectroscopic analysis as well as acidic hydrolysis of 1 leading to (鈭?-epi-伪-bisabolol (2) and 6-deoxy-d-gulose (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-伪-bisabolol glycoside of plant origin.
