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.
