OBJECTIVE
To study the chemical constituents in the seeds of Ziziphus mauritiana.
METHODS
The constituents were isolated by silica column chromatography and their structures were elucidated by physico-chemical properties and spectroscopic analysis.
RESULTS
Twelve compounds were isolated from the seeds of Ziziphus mauritiana and identified as betulinic aldehyde (1), betulinic acid (2), ceanothic acid (3), frangufoline (4), spinosin (5), beta-sitosterol (6), daucosterol (7), daucosterol-6'-octadecanoate (8), sucrose (9), docosanoic acid (10), stearic acid (11), palmitoleic acid (12).
CONCLUSIONS
All the compounds are obtained from Ziziphus mauritiana seeds for the first time and compounds 4,5 and 8 are isolated from this plant for the first time.
