[Study on chemical constituents of Citrullus vulgaris Schrad vine (II)].
OBJECTIVE
To study the chemical constituents of ethyl acetate fraction of Citrullus vulgaris Schrad vine.


METHODS
Compounds were isolated and purified by polyamide column chromatography, silica gel column chromatography, thin layer chromatography and sephadex gel column chromatography. Their structures were elucidated on the basis of physicochemical properties and spectral data.


RESULTS
Ten compounds were isolated from Citrullus vulgaris Schrad vine and elucidated as: pentadecanoic acid (1), monopentadecanoin (2), 2, 3-dihydroxypropyl nonadecoate (3), lignoceric acid-2, 3-dihydroxy-propanenyl ester (4), lancerebroside 5 (5), salicylic acid (6), 4-hydroxybenzoic acid (7), hydroquinone (8), succinic acid (9) and vanillic acid (10).


CONCLUSIONS
Compounds 1 - 10 are obtained from Citrullus vulgaris Schrad vine for the first time.
