Objectives : In this study, we investigate that Euphorbiae lathyridis Semen extract contributes to growth inhibitory effect and anti-cancer activity on the HT-29 human colon cancer cells. Methods : Euphorbiae lathyridis Semen was extracted from the Semen of the plant using 80% Methanol. The Euphorbiae lathyridis Semen extract was treated to different concentrations for 24 hr, 4Shr or 72hr. Growth inhibitory effect was analyzed by measuring FACS study and MTT assay. Cell apoptosis was confirmed by surveying caspases cascades activation using Westem blot. Results : Exposure to Euphorbiae lathyridis Semen extract (0.4mg/ml) results in an inhibitory effect on cell growth in HT-29 cells. Growth inhibition by Euphorbiae lathyridis Semen extract in HT-29 cells was related with the inhibition of proliferation and induction of apoptosis. The Euphorbiae lathyridis Semen extract induces DNA fragmentation in HT-29 cells. Furthermore, Euphorbiae lathyridis Semen extract induces cell apoptosis through the activation of caspases-3, caspase-9 and PARP cleavage. Conclusion : Euphorbiae lathyridis Semen extract induces apoptosis in human colon cancer cells, therefore, we suggest that Euphorbiae lathyridis Semen extract can be used as a novel class of anti-cancer drugs.

Objectives. In this study, we investigate that methanol extract of Euphorbiae lathyridis Semen contributes to growth inhibitory effect on the HT-29 human colon cancer cells. Methods. Euphorbiae lathyridis Semen (ELS) was extracted with 80% methanol. HT-29 cells were treated with different concentrations of ELS extract for 24-72 hrs. Growth inhibitory effect was determined by MTT assay. Cell apoptosis was determined by surveying caspases cascades activation using Western blot. Cell cycle arrest was analyzed by flow cytometry with PI staining. Results. Exposure to ELS extract showed in inhibitory effects on HT-29 cell growth as a dose-dependent manner. Cell growth inhibition by ELS extract was related with induction of cell apoptosis with DNA fragmentation through the activation of caspases-3, caspase-9 and PARP cleavage. Conclusion. ELS extract significantly inhibited cell growth and induced cell apoptosis in HT-29 human colon cancer cells, therefore, These results suggest that ELS extract can be used as chemoprevention agent of colon cancers.

Two diterpenes and one new sucrose isovaleryl ester having inhibitory effects on melanogenesis in B16 mouse melanoma were isolated from Euphorbiae Lathyridis Semen which has been used in traditional medicine for cancer, tumors and warts. New sucrose isovaleryl ester was identified as ${\alpha}-D-glucopyranoside$, $3,4,6-tris-O-(3-methyl-l-oxobutyl)-{\beta}-D-fructofuranosyl$, 2,6-bis(3-methylbutanoate) and two diterpenes were identified as ingenol-20-palmitate and 5,10-diacetyl-3-benzoyllathyrol$(Euphorbia\;factor\;L_3)$ from their spectral data.

In order to search for antioxidants from the plants, eighty-two kinds of herbal medicines were investigated. The MeOH extracts of Euryales Semen, Alpiniae Officinari Rhizoma. Drynariae Rhizoma, Sophorae Flos, Trachelospermi Caulis, Crassirhizomae Rhizoma, Euphorbiae lathyridis Semen, Lini Semen, Myristicae Semen, Epimedii Herba, Santali Lignum rubrum, Perillae Herba, Amomi Tsao-Ko Fructus and Garanii Herba showed potent antioxidative activities using the 1,1-diphenyl-2-picrylhydrazyl free radical generating system.
