One new phenolic glycoside (1) and one new benzofuran derivative (2) were isolated from the leaves of Illicium dunnianum. The structures of these compounds were established by using comprehensive spectroscopic data analysis, including the 1D and 2D NMR, IR, HR-ESI-MS, electronic circular dichroism and comparison with literature data. All isolates were evaluated for the inhibition against the production of NO by LPS-stimulated RAW 264.7 macrophages.

Three new phenylpropenoid glycosides (1–3), and five undescribed shikimic acid derivatives (4–8), together with six known analogues (9–14), were obtained from the dried leaves of Illicium dunnianum.

Eight previously unreported phenolic acids (1-8), including three new phenylpropenoid glycosides (1-3), and five undescribed shikimic acid derivatives (4-8), together with six known analogues (9-14), were obtained from the dried leaves of

Phytochemical investigations on the dry leaves of Illicium dunnianum have led to the isolation of 24 lignans. Illiciumlignans G–K (1–5) were five undescribed benzofuran lignans, illiciumlignan L (6) was one undescribed ditetrahydrofuran lignan, illiciumlignans M–O (7–9) were three new sesquilignans, and compounds 10, 12, 13, 15, and 18–21 were firstly isolated from the genus Illicium. Their structures were elucidated by detailed spectroscopic analyses (UV, IR, HR-ESI-MS, and NMR) and CD experiments. All isolates were evaluated by measuring their inhibitory effects on PGE2, and NO production in LPS-stimulated RAW 264.7 macrophages.

A new phenylpropanoid allopyranoside (

A new phenylpropanoid allopyranoside (1) and a new indolinone alkaloid (2) were isolated from the rhizomes of Actaea dahurica (syn. Cimicifuga dahurica). The structures of those two compounds were deduced as cimicifugaside F (1) and 3E,11E-(3-methyl-2-butenylidene acid)-2-indolinone-1-O-β-d-glucopyranoside (2) by detailed analysis of their MS, 1D and 2D NMR data and comparison with literatures. Additionally, the isolates were evaluated for their inhibitory effects on the production of NO by LPS-stimulated RAW 264.7 macrophages.
