[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).

CONCLUSION

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