  • 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.

  • The detailed $^1$H and $^{13}$ C NMR assignments of a novel sucrose isovaleryl ester isolated from the seed of Euphorbia Lathyris L., were achieved by one-and two-dimensional techniques. The new sucrose ester was characterized as an $\alpha$-D-glucopyranoside, 3,4,6-tris-O-(3-methyl-1-oxobutyl)-$\beta$-D-fructofuranosyl, 2,6-bis(3-methylbutanoate); sucrose 4,7,8,11,12-pentaisovalerate by MS and NMR experiments.
