Chemical components from the hexane extracts of Glochidion daltonii stems (Euphorbiaceae)

Keetaphat Konthong

Abstract


The isolation of pure compound from crude hexane  extracts of G. daltonii stems was carried out by chromatographic techniques. One pure compound was obtained from hexane crude extracts of G. daltonii stems whichwas white needle crystal with melting point 211-212°C . The structure was identified by spectroscopic techniques 1H NMR 13C NMR  DEPT-90  DEPT-135 respectively.  The comparison of these spectra  to the reference spectra of lupane indicated that pure compound from the hexane extracts of the G. daltonii stems is   lup-20(29)ene-3α,23-diol
