One new chroman glycoside derivative from unmatured fruits of Citrus aurantium / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of the unmatured fruits of Citrus aurantium.</p><p><b>METHOD</b>The AcOEt fraction of the methanol extracts of the unmatured fruits of C. aurantium were subjected on column chromatographies including silica gel, RP-18 and HPLC. Compound structures isolated were determined on the basis of spectroscopic data.</p><p><b>RESULT</b>Three compounds were isolated from the unmatured fruits of C. aurantium, which were identified as citrauranoside (1), limonexin (2) and limonin (3).</p><p><b>CONCLUSION</b>Compound 1 is a new chroman glycoside derivative, named as citrauranoside.</p>
