title: A new phenylpropanoid glucoside and a chain compound from the roots of Allium tuberosum.
abstract: A new phenylpropanoid glucoside tuberosinine D (1) and a chain compound (Z)-11R,12S,13S-trihydroxy-9-octadecenoate (2) were isolated from the roots of Allium tuberosum. The absolute configuration of 1 was established by comparing of experimental and calculated electronic circular dichroism. The absolute configuration of 2 was determined using the modiﬁed Mosher's method for the first time.
