Objective:
To study the chemical constituents from Melicope ptelefolia.
Methods:
Several chromatographic methods were applied to isolate and purify compounds. Their structures were identified on the basis of physicochemical properties and spectroscopic data.
Results:
Seven compounds were isolated and elucidated as n-octadecanyl palmitate (I), beta-sitosterol (II), palmitic acid (III), 3, 5,3'-trihydroxy-8,4'-dimethoxy-7-(3-methylbut-2-enyloxy) flavone (IV), daucosterol (V), salylic acid (VI), kaempferol-3-O-alpha-D-arabinpyranoside (VII).
Conclusion:
Compound VII is isolated from the genus for the first time, Compounds V and VI are isolated from Melicope ptelefolia for the first time.
