AI Article Synopsis
- - The study aims to explore the chemical components of Euphorbia helioscopia and evaluate their potential antitumor effects.
- - Researchers utilized various chromatographic techniques and spectroscopic methods to isolate and identify nine distinct chemical compounds from the plant, including euphohelioscopin A and helioscopinolide A.
- - Among the isolated compounds, helioscopinolide A demonstrated significant cell proliferation inhibition in the MCF-7 breast cancer cell line, highlighting its potential as an antitumor agent.
Article Abstract
Objective: To investigate the chemical constituents of Euphorbia helioscopia and their antitumor activities.
Methods: Normal phase silica gel, RP-18 silica gel and Sephadex LH-20 column chromatographies combined with recrystallization were used to isolate and purify the constituents. Their structures were identifided by spectroscopic methods, including 1H-NMR, 13C-NMR, ESI-MS and EI-MS. And the antitumor activities of some of chemical constituents in vitro were detected by sulphorhodamine B protein staining.
Results: Nine compounds were isolated and their structures were identified as euphohelioscopin A (1), euphoscopin (2), 9, 19-cyclolanost-23E-ene-3, 25-diol (3), euphoscopin C (4), euphornin A (5), euphoheliosnoid A (6), ent-kaurane-3-oxo-16beta, 17-diol (7), 9, 19-cyclolanost-25-ene-3beta, 22-diol (8) and helioscopinolide A(9) Compound 9 showed effect on inhibiting the cell proliferations of MCF-7 cell line.
Conclusion: Compounds 3, 7, 8 and 9 are obtained from this plant for the first time, and compound 9 shows the potential antitumor activity.

Oxidants used in the ISCO technology usually require activation by activators to degrade contaminants. However, this study investigated degradation of 15 typical halogenated hydrocarbons by five common ISCO oxidants (PS, PMS, HO, KMnO, SPC) without activation in both pure water and real groundwater. Unactivated PS could degrade 14 halogenated hydrocarbons, excluding tetrachloromethane.
