Chemical Constituents from Euphorbia Altotibetica

Objective: To study the chemical constituents from Euphorbia altotibetica.Methods: Chemical constituents were isolated by chromatographic methods and identified by physiochemical and spectral analysis.Results: Seven compounds were isolated and identified as S-(+)-1,5-dipheny-3-hydroxy-1-penta-none(1),scopoletin(2),umbelliferon(3),pinoresinol(4),(+)-syringaresinol(5),daphnoretin(6),isoneochamaejasmin A(7).Conclusion: All these compounds were obtained from Euphorbia altotibetica for the first time.
