Title: Chemical Constituents from <i>Euphorbia helioscopia</i>
Abstract: AIM: To study the chemical constituents of Euphorbia helioscopia. METHODS: Compounds 1-10 were isolated and purified by silica gel, Sephadex LH-20 and Rp-18 chromatogarphy. Their structures were elucidated mainly by spectroscopic methods. RESULTS: Ten known compounds, helioscopinolide A(1), helioscopinolide B(2), scopoletin(3), scoparone(4), isoscopoletin(5), licochalone A(6), quercelin(7), 7, 4’-dihydroxy-5-methoxy flacanone(8), 2’, 4’-dihydroxy-6’-methoxydihydrochalcone(9) and pinocembrin(10), were isolated and structurally elucidated. CONCLUSION: Compound 3-5 and 8-10 were isolated from this plant for the first time. 2D NMR spectrum data of 2 were also reported in this paper.
