Two New Sequiterpenoids from Helicteres angustifolia
摘要:
A new sesquiterpenoid lactone, 3,6,9-trimethyl-pyrano[2,3,4-de] chromen-2-one (1) and a novel sesquiterpenoid quinone, 6-[2-(5-acetyl-2,7-dimethyl-8-oxo-bicyclo [4.2.0] octa-l,3,5-trien-7-yl)-2-oxo-ethyl]-3,9-dimethylnaphtho[1,8-bc]pyran-7,8-dione (2) together with a known perezone (3) were isolated from the roots of Helicteres angustifolia. The structures were elucidated as mainly on the basis of 1D and 2D NMR spectroscopic data.
