Terpenoids from Tripterygium hypoglaucum and Their Anti-Inflammatory Activity.

A new diterpenoid, 19-O-β-D-glucopyranosyl-labda-8(17),14-dien-13-ol (1), and nine known triterpenes (2-10) were isolated from the aerial parts of Tripterygium hypoglaucum. All structures were elucidated by NMR spectroscopic methods. Moreover, the inhibition of superoxide anion generation and elastase release were also examined. [ABSTRACT FROM AUTHOR]
