A new abietane diterpene, the 19-O-beta-D-glucopyranoside of 16-hydroxylambertic acid was isolated from the leaves of Quillaja brasiliensis together with a known prosapogenin (3-O-beta-D-glucuronopyranosyl- quillaic acid), quercetin, and rutin. The new compound was identified by chemical and spectroscopic methods.

Abstract
A new abietane diterpene, the 19-O-beta-D-glucopyranoside of 16-hydroxylambertic acid was isolated from the leaves of Quillaja brasiliensis together with a known prosapogenin (3-O-beta-D-glucuronopyranosyl- quillaic acid), quercetin, and rutin. The new compound was identified by chemical and spectroscopic methods.
