Objective:
To study the chemical constituents of the Ficus microcarpa.
Methods:
Isolation and identification were carried out by using various chromatography techniques and spectral methods.
Results:
Eight compounds were isolated. Their structures were identified as beta-amyrone (I), lupeol (II), lupeol acetate (III), maslinic acid (IV), epifriedelinol (V), stearic acid (VI), beta-sitosterol (VI), daucosterol (VI).
Conclusion:
Compounds I, II, VI are isolated from this plant for the first time.
