Abstract

Bioactivity‐guided fractionation of the methanolic extract from the seeds of Euphorbia lathyris led to the isolation of eighteen lathyrane‐type diterpenoids including a new one,Euphorbia Factor L29 (1). Their chemical structures were elucidated by extensive NMR spectroscopic data including 2D‐NMR, and HR‐ESI‐MS as well as CD data. All isolates (1‐18) were found to inhibit the nitric oxide production in LPS‐induced RAW 264.7 macrophages, with their IC50 values in the range of 11.2 ‐ 52.2 μM.
