[One new chroman glycoside derivative from unmatured fruits of Citrus aurantium].

ABSTRACT

OBJECTIVE: To study the chemical constituents of the unmatured fruits of Citrus aurantium. METHOD: 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. RESULT: Three compounds were isolated from the unmatured fruits of C. aurantium, which were identified as citrauranoside (1), limonexin (2) and limonin (3). CONCLUSION: Compound 1 is a new chroman glycoside derivative, named as citrauranoside.
