[Studies on chemical constituents from fruits of Trichosanthes kirilowii Maxim].
OBJECTIVE
To study the chemical constituents of methanol extract from the dried ripe fruits of Trichosanthes kirilowii.


METHODS
Silica gel column chromatographic technology and Sephadex G-10 gel filtration were employed to separate and purify the methanol extract, and the compounds obtained were elucidated by means of IR, MS, 1HNMR and authentic specimens.


RESULTS
Palmitic acid, stigmast-7-en-3 beta-ol, stigmast-7-en-3-O-beta-D-glucopyranoside, galactonic acid gamma-lactone and galactose were isolated and elucidated.


CONCLUSIONS
All the compounds were obtained from the fruit s of T. kirilowii for the first time.
