Abstract
Castanopsis genus (Fagaceae) were rich in plant polyphenols and often used as medicinal plants. In this study, two new lignan dimer compounds with anti-inflammatory activity and four known compounds were isolated and identified from 80% methanolic extract of Castanopsis chinensis leaves. The structure determination supported by computational chemistry and extensive spectroscopic analysis. Two new lignan dimer compounds significantly inhibited LPS-induced NO production in RAW 264.7 cells at 10 µM without cytotoxicity.
期刊介绍：
The Journal of Natural Medicines is an international journal publishing original research in naturally occurring medicines and their related foods and cosmetics. It covers:
-chemistry of natural products
-biochemistry of medicinal plants
-pharmacology of natural products and herbs, including Kampo formulas and traditional herbs
-botanical anatomy
-cultivation of medicinal plants.
The journal accepts Original Papers, Notes, Rapid Communications and Natural Resource Letters. Reviews and Mini-Reviews are generally invited.
