[Structure determination of the constituents from Citrus grandis Osbeck].
OBJECTIVE
To isolate the chemical constituents of the peelings of Citrus grandis and determine their structure.


METHODS
Column chromatography and PTLC were applied to isolating and purifying the chemical constituents, and 1H NMR and 13C NMR were used to elucidate their structure.


RESULTS
4 compounds were isolated as meranzin hydrate(1), roseoside(2), 8-(3-beta-D-syl-2-hydrox-3-methylbutyl)-7-methoxycoumarin(3) and glucose(4).


CONCLUSIONS
Compound 2 was isolated as a carotenoid from this genus for the first time.
