Abstract

Inflammation is related to many diseases. Lindera akoensis Hayata was often used in folktherapy in Taiwan for inflammation. In this study, three new flavonol acyl glycosides, namelykaempferol-3-O--D-4",6"-di-(E)-p-coumaroylglucoside (1), 3"-(E)-p-coumaroylafzelin (2) and 40-Omethyl-2",4"-di-(E)-p-coumaroylquercitrin (3), and three components, 3-dodecyl-4-hydroxy-5-methyldihydrofuran-2-one (4), 2-acetoxyclovan-9-ol (5), (1,4,6)-trihydroxyeudesmane(6) that were isolated from the natural product for the first time were obtained along with 25 knowncompounds from L. akoensis. Their structures were determined by comprehensive spectroscopicanalyses (1D and 2D NMR, EI-, ESI- and HRESI-MS). The ability of 1 to decrease the LPS-stimulatedproduction of nitrite in RAW264.7 cell was evaluated, showing an IC50 value of 36.3 ± 3.2 μM.This result supports the value of L. akoensis as a traditional medicine resource.
