Chemical constituents of Euphorbia antiquorum Linn. core having cytotoxicity against cancer cell lines
Abstract:
The chemical constituents of finely crushed air-dried core of Euphorbia antiquorum Linn. in hexane crude extract and ethyl acetate crude extract were separated by column chromatography on silica gel. Structure elucidation of the isolated compounds were investigated using physical properties and spectroscopic techniques. Six compounds were isolated and identified. There were five diterpene compounds namely, ent-Atis-16-ene-3,14-diene or Deoxyantiquorin (1), ent-(13S)-Hydroxyatis-16-ene-3,14-dione or Antiquorin (2), ent-8 alpha,14 alpha-Epoxyabieta-11,13(15)-diene-16,12-olide or Jolkinolide A (3), ent-16 alpha,17-Dihydroxyatisan-3-one (4) and ent-13,3 beta-dihydroxy-14-oxo-atis-16-ene (6) . The structure of compound (5) which was needle crystals (mp. 197-199ํC) was still under investigation. Moreover, this is the first report of compound 1, 3, 4, 5 and 6 from this plant. All compounds were tested for cytotoxicity against cancer cell lines : HS27 (fibroblast), Hep-G2 (hepatoma), SW620 (colon), Chago (lung), Kato-3 (gastric) and BT474 (breast). Jolkinolide A (3) and compound 5 showed significant cytotoxicity against all cancer cell lines. Ent-Atis-16-ene-3,14-diene (1) showed high cytotoxicity against Kato-3 (gastric) and ent-13,3 beta-dihydroxy-14-oxo-atis-16-ene (6) exhibited moderate cytotoxicity against SW620 (colon) and Kato-3 (gastric). Moreover, this is the first report of cytotoxicity test of 6 compounds from Euphorbia antiquorum Linn.
