Illiciumlignans G–O from the leaves of Illicium dunnianum and their anti-inflammatory activities

Abstract

Phytochemical investigations on the dry leaves of Illicium dunnianum have led to the isolation of 24 lignans.

Eight new phenolic acids from the leaves of Illicium dunnianum and their osteoprotective activities

“…In our previous research, 24 lignans (including nine previously uncharacterized compounds), one new phenolic glycoside, and one new benzofuran derivative with anti-inammatory activities were isolated from the leaves of I. dunnianum. 18,19 As a part of further investigation of constituents with activities on osteoblastogenesis or osteoclastogenesis from the leaves of I. dunnianum has led to the isolation and structural elucidation of eight previously unreported phenolic acids (1-8), including three new phenylpropenoid glycosides (1-3), and ve undescribed shikimic acid derivatives (4-8), together with six known analogues (9-14) (Fig. 1).…”
